Big picture

Time period	Development summary	More details
Pre-19th century	Early observations without etiological understanding	Fungal diseases such as oral thrush and tinea are observed and named in antiquity, but their causes remain unknown. Ancient Greek physicians describe clinical manifestations compatible with candidiasis, and Roman physicians coin clinical terminology still in use today. No distinction is yet made between fungal, bacterial, or parasitic disease.
1835–1870	Founding of medical mycology as a discipline	The germ theory era begins with Agostino Bassi's 1835 demonstration that a fungus causes muscardine disease in silkworms — the first proof that a microorganism causes an infectious disease in animals. Within a decade, Schönlein, Remak, Gruby, Berg, and Malmsten establish fungal etiologies for favus, tinea, and thrush in humans. Medical mycology emerges as a recognisable discipline, though it is soon overshadowed by bacteriology.
1870–1910	Expansion of known fungal pathogens	A surge of discovery defines the major pathogenic fungal genera and diseases: Malassezia, Sporothrix, Cryptococcus, Madurella, Coccidioides, Histoplasma, and Paracoccidioides are all described in this period. Most are initially misclassified as protozoa before being reclassified as fungi. Clinical descriptions rely entirely on morphology and culture.
1910–1950	Consolidation of taxonomy and early diagnostics	Emmons standardises dermatophyte taxonomy; Sabouraud establishes the foundational culture media still bearing his name; Carter, Pinoy, and Carrión create clinical classification frameworks for mycetoma and chromoblastomycosis. Skin testing and complement fixation begin to be applied as diagnostic tools. Pablo Negroni plays a central role in establishing South American mycology.
1950–1970	First antifungal era and institutional development	The discovery of nystatin (1950) and amphotericin B (1955) provides the first effective therapies for systemic fungal infections. ISHAM is founded (1954), formalising medical mycology as an international discipline. Griseofulvin becomes available for dermatophyte infections. The first cases of mucormycosis and hyalohyphomycosis in immunocompromised patients are documented, anticipating the coming era of opportunistic infections.
1970–1990	The immunocompromised host and the azole revolution	The rise of transplant medicine, cancer chemotherapy, and the HIV/AIDS epidemic transforms medical mycology. Opportunistic infections caused by Candida, Aspergillus, Cryptococcus, Pneumocystis, and Histoplasma become major causes of morbidity and mortality. Ketoconazole (1978), fluconazole (1990), and itraconazole (1982) provide the first oral systemic antifungals. TMP-SMX prophylaxis dramatically reduces Pneumocystis mortality in HIV patients.
1990–2010	Molecular revolution and diagnostic advances	DNA sequencing and molecular phylogenetics reshape fungal taxonomy, revealing that many morphological species are in fact species complexes. MALDI-TOF mass spectrometry (2004) revolutionises laboratory identification. Voriconazole (2002) and caspofungin (2001) provide new antifungal classes. Galactomannan detection enables earlier diagnosis of invasive aspergillosis. The first cases of azole-resistant Aspergillus fumigatus are documented.
2010–present	Emerging resistance, new pathogens, and global recognition	Candida auris (2009) emerges as a multidrug-resistant global threat. Environmentally-driven azole resistance in A. fumigatus spreads across continents. The COVID-19 pandemic triggers an unprecedented mucormycosis epidemic in India (2021). The WHO publishes the first Fungal Priority Pathogens List (2022), marking global institutional recognition of fungal infections as a major public health challenge. Novel antifungal agents enter clinical trials targeting mechanisms beyond existing drug classes.

Full timeline

Year	Event type	Fungal species	Disease	Details	Geographical location
c. 400 BCE	Research	Candida albicans	Oral candidiasis	Ancient Greek physician Hippocrates describes two cases of oral aphthae associated with severe underlying diseases in his work Epidemics, observations that modern mycologists identify as likely oral candidiasis. The association of the condition with debilitating illness anticipates the modern understanding of Candida as an opportunistic pathogen, a concept not formally established until the 19th century.	Ancient Greece
Ancient times	Classification	Trichophyton, Microsporum, Epidermophyton	Tinea	Ancient Romans coin the term tinea (meaning bookworm) to describe the circular lesion produced by dermatophytic fungi on the skin and scalp. The term persists into modern clinical mycology as the standard designation for dermatophyte infections across body sites.	Roman Empire
1834	Research	—	Favus	German anatomist Robert Remak analyzes a lesion known as favus under the microscope and observes multiple filaments, marking one of the first systematic scientific examinations of a dermatophyte infection. This work contributes to the emerging scientific study of dermatophytoses in the 19th century.	Europe
1835	Discovery	Beauveria bassiana	—	Italian entomologist Agostino Bassi publishes Del mal del segno, demonstrating after 25 years of research that the muscardine disease devastating silkworm farms across Europe is caused by a microscopic parasitic fungus, later named Beauveria bassiana in his honour. This is the first demonstration that a microorganism causes an infectious disease in animals, predating the germ theory of Pasteur and Koch and directly inspiring Johann Lukas Schönlein's subsequent identification of the fungal origin of favus in humans.	Italy
1835	Discovery	Candida	Candidiasis	Veron postulates intrauterine transmission and describes the first patient with esophageal candidiasis, representing one of the earliest clinical descriptions of the disease beyond oral manifestations. This observation anticipates the modern understanding of candidiasis as a systemic condition capable of affecting deep tissues and internal organs, a significance that would only become fully apparent in the 20th century with the rise of immunocompromised patient populations.	International
1839	Discovery	Candida albicans	Candidiasis	Langenbeck isolates the causal microorganism from the mouth of a patient with aphthae, providing the first microbiological evidence of the candidiasis agent.	Europe
1839	Discovery	—	Tinea favosa	Swiss physician Johann Lukas Schönlein identifies the fungus responsible for favus, establishing for the first time a fungal etiology for a human skin disease and laying groundwork for the field of medical mycology.	Europe
1841	Discovery	—	Tinea	David Gruby publishes work on the fungal origin of tinea, describing the role of fungi in skin infections and advancing early mycological research.	Europe
1841	Research	Candida albicans	Oral candidiasis	Berg demonstrates the fungal origin of oral lesions and reproduces the condition in healthy children, fulfilling an early form of Koch's postulates for candidiasis. By experimentally reproducing the infection, Berg provides the first causal proof linking a fungus to a human disease, a methodological advance that would influence the broader germ theory movement and set the standard for etiological proof in medical mycology throughout the 19th century.	Europe
1842	Discovery	—	Mycetoma	J. McGill describes foot tumour for the first time in India, providing the first documented account of mycetoma. Godfrey subsequently registers the first documented descriptions of the condition between 1844 and 1845, and Eyre and Godfrey describe 40 treated patients between 1844 and 1848, establishing mycetoma as a new clinical entity characterised by progressive swelling with multiple fistulae and grains of varying colours and consistencies.	India
1842	Research	Candida albicans	Candidiasis	Gruby describes the fungus before the Paris Academy of Sciences, identifies it as the true agent of thrush, postulates intrauterine transmission, and reports the first candidiasis — later classified by the same author in 1847 as Sporotrichum.	France
1845	Discovery	Trichophyton	Dermatophytosis	Lebert identifies the fungus as a producer of chromoblastomycosis-like lesions; Malmsten describes a new genus Trichophyton, formalizing the taxonomy of dermatophytes.	Europe
1846	Discovery	Malassezia furfur	Pityriasis versicolor	Eichstedt describes the fungus responsible for pityriasis versicolor, a superficial mycosis of worldwide distribution affecting the stratum corneum of the skin. The authors do not yet propose a formal designation for the etiological agent.	Europe
1846	Research	Candida albicans	Candidiasis	Berg recognises debilitating diseases as the main predisposing factor for candidiasis, anticipating the modern concept of Candida as an opportunistic pathogen.	Europe
1847	Discovery	Microsporum	Tinea capitis	A new fungal genus is established, later identified as Microsporum, expanding the taxonomic framework for dermatophytes.	Europe
1853	Classification	Microsporum furfur	Tinea versicolor	Charles-Philipe Robin reclassifies the pityriasis versicolor agent as Microsporum furfur and describes the disease as a dermatophytosis similar to Microsporum audouinii.	Europe
1853	Classification	Candida albicans	Candidiasis	Robin names the organism Oidium albicans and describes systemic candidiasis in debilitated patients.	France
1855	Research	—	Mycetoma	Ballingali observes bone destruction in two clinical cases of mycetoma, documenting for the first time the osteoarticular involvement that characterises advanced disease. This finding establishes that mycetoma is not merely a superficial infection but a progressive destructive condition capable of invading bone, which would become a key criterion for staging disease severity and informing surgical versus medical treatment decisions in subsequent clinical practice.	India
1861	Classification	—	Mycetoma	British surgeon Henry Vandyke Carter distinguishes mycetoma from other tumour types and introduces the term mycetoma, referring to the grains of the causal agent as fungus particles.	India
1861	Discovery	Candida	Candidiasis	Zenker documents the first case of candidiasis in deep tissues, establishing that Candida can cause invasive infection beyond mucosal surfaces.	Europe
1874	Discovery	Malassezia	Seborrheic dermatitis	Malassez describes yeast cells in a patient with dermatitis seborrheica and denominates the structures as spores. Bizzozero independently observes the same forms on skin and names the fungus Saccharomyces sphaerelris and Saccharomyces ovalis based on morphology.	Europe
1876	Publication	—	Mucormycosis	Furbringer publishes the earliest reliable reports of mucormycosis, representing the first documented cases in which fungal presence in tissues is adequately demonstrated. Earlier 19th-century cases are considered doubtful due to lack of histological confirmation. This work establishes the methodological standard of tissue-based histological proof for fungal diagnosis, a principle that underpins all subsequent mycological pathology and remains central to the diagnosis of invasive fungal infections today.	International
1877	Research	Candida albicans	Candidiasis	Grawitz describes the dimorphic character of the yeast. In the same year, Forbes studies the morphology of Candida albicans in London, examining a three-year-old girl with tongue and nail involvement that may correspond to the first case of mucocutaneous candidiasis.	Europe
1884	Discovery	Mucor corymbifera	Mucormycosis	L. Lichtein isolates the mucorales from bread, studies the disease in rabbits and coins the names Mucor corymbifera and Mucor rhizopodiformis.	International
1885	Discovery	Mucor corymbifer	Mucormycosis	Arnold Paltner describes the first case of disseminated rhinocerebral mucormycosis and without culturing the organism names it Mucor corymbifer.	International
1885	Publication	—	—	German Sims Woodhead and Arthur Hare publish Pathological Mycology: An Enquiry into the Etiology of Infectious Diseases, one of the first British textbooks to systematically address fungi as causes of human infection. The work represents an early attempt to establish medical mycology as a distinct discipline, though the term mycology in this context is soon supplanted by bacteriology in subsequent textbooks.	United Kingdom
1886	Classification	Mucor pusillus	Mucormycosis	W. Lindt describes Mucor pusillus and Mucor racemosus in humans and animals, expanding the known pathogenic mucorales.	International
1889	Classification	Malassezia	—	Baillon creates the genus Malassezia, placing the organism within the Blastomycetes.	Europe
1891	Discovery	Hortaea werneckii	Tinea nigra	Brazilian physician Alexandre Cerqueira describes tinea nigra in Salvador, Brazil, naming it queratomicosis nigricans palmaris. His son Castro Cequeira Pinto later popularizes the condition.	Brazil
1892	Discovery	Coccidioides immitis	Coccidioidomycosis	Argentine medical student Alejandro Posadas and his mentor Wernicke describe the first case of coccidioidomycosis in Buenos Aires, in an Argentine soldier with widespread cutaneous and disseminated disease. They produce a detailed description of the clinical manifestations, histopathology, and tissue phase of the agent, and reproduce the disease in animals, but erroneously classify the organism as a protozoan of the genus Psorosperma.	Argentina
1894	Discovery	Cryptococcus neoformans	Cryptococcosis	Sanfelice isolates an encapsulated yeast from fermented grape juice and demonstrates its pathogenicity by inoculating it into animals, naming it Saccharomyces neoformans. In the same year, the first human case of cryptococcosis is described by German pathologist Busse, who observes the yeast in a lesion on the tibia of a woman who later dies of disseminated disease; Busche subsequently isolates the fungus in culture.	Italy, Germany
1894	Discovery	Madurella mycetomatis	Mycetoma	R. Boyce and N.E. Surveyor establish that, in addition to fungi, actinomycetes are also causative agents of mycetoma. In the same year, M.H. Vincent isolates Streptothrix (Actinomadura) madurae from a case in Algeria, and Laveran identifies black grains from a previously reported mycetoma case, naming the fungus Streptothrix (Madurella) mycetomati.	Algeria
1896	Classification	Coccidioides immitis	Coccidioidomycosis	Rixford and Gilchrist formally describe the organism from the first North American cases in California, naming it Coccidioides immitis — Coccidioides meaning "resembling Coccidia" and immitis from the Latin for "harsh," reflecting the severe clinical course. The organism is still considered a protozoan at this stage.	United States
c. 1898	Discovery	Sporothrix schenckii	Sporotrichosis	Benjamin Schenck, a medical student in the United States, describes the first case of sporotrichosis presenting as the classic nodular lymphangitic form of the disease. Smith subsequently identifies and cultures the fungus, classifying it within the genus Sporothrix.	United States
1900	Discovery	Sporothrix schenckii	Sporotrichosis	Hektoen and Perkins describe the second case of sporotrichosis in Chicago, Illinois — a boy who sustains a hammer blow injury to a finger and develops a lesion that resolves spontaneously, illustrating the traumatic inoculation route characteristic of the infection.	United States
1900	Classification	Coccidioides immitis	Coccidioidomycosis	Ophüls and Moffitt demonstrate that Coccidioides immitis is a fungus rather than a protozoan, correcting the original classification and placing coccidioidomycosis firmly within the field of medical mycology.	United States
1901	Classification	Cryptococcus neoformans	Cryptococcosis	Vuillemin considers Saccharomyces neoformans incorrectly classified within Saccharomyces based on its biochemical and morphological characteristics and its reproduction, and transfers it to the genus Cryptococcus.	International
1903	Treatment	Sporothrix schenckii	Sporotrichosis	French dermatologist Raymond Sabouraud proposes the use of potassium iodide as a treatment for sporotrichosis, which is a common disease in France at the turn of the 20th century. Potassium iodide becomes a longstanding therapy for the infection, particularly in resource-limited settings.	France
1904	Classification	Pityrosporum malassezii	Pityriasis versicolor	French dermatologist Raymond Sabouraud classifies the spores observed in pityriasis versicolor within Blastomycetes, names the fungus Pityrosporum malassez, and establishes it as the etiological agent of dandruff. Sabouraud also separates the filament-forming agent (Malassezia furfur) from the yeast forms (Pityrosporum malassezii), placing them in different genera.	Europe
1905	Classification	Cryptococcus neoformans	Cryptococcal meningitis	Two cases of meningitis are described and the fungus is isolated; it is given the name Torula meninges and isolated from two additional meningitis cases under the name Torula histolytica.	International
1906	Discovery	Histoplasma capsulatum	Histoplasmosis	American pathologist Samuel Taylor Darling describes histoplasmosis for the first time in the Panama Canal construction zone, performing an autopsy on a patient with hepatosplenomegaly and pulmonary damage — signs closely resembling systemic leishmaniasis. The following year he observes two new cases with histiocytes containing intracellular microorganisms and classifies them as a protozoan without blepharoplast.	Panama
1906	Classification	Madurella mycetomatis	Mycetoma	Brumpt proposes the genus Madurella to classify the filamentous fungus isolated as Madurella mycetomatis, and suggests that Indiella species cause white-grain mycetomas.	International
1907	Discovery	Sporothrix schenckii	Sporotrichosis	Lutz and Splendore describe the first case of natural sporotrichosis infection in rats in Brazil, establishing an animal reservoir for the disease and anticipating later recognition of zoonotic transmission routes.	Brazil
1908	Discovery	Paracoccidioides brasiliensis	Paracoccidioidomycosis	Brazilian physician and naturalist Adolfo Lutz observes two patients with lesions on the left labial commissure and tongue base, describes the clinical and histopathological aspects, isolates the fungus in culture, and confirms its dimorphism. In his original description he erroneously identifies it as Coccidioides immitis; Lutz notes certain differences from C. immitis and considers it an intermediate form between C. immitis and Blastomyces dermatitidis.	Brazil
1908	Research	Sporothrix schenckii	Sporotrichosis	Splendore reports the presence of asteroid bodies — yeast cells surrounded by radiating extensions — around Sporothrix cells, identifying a characteristic histopathological marker that becomes a useful diagnostic feature of sporotrichosis tissue specimens.	Brazil
1909	Discovery	Pneumocystis jirovecii	Pneumocystis pneumonia	Chagas identifies the organism Pneumocystis in the lung of a guinea pig experimentally infected with Trypanosoma, initially believing it to be part of the trypanosome's life cycle rather than a separate organism.	Brazil
1910	Treatment	—	Dermatophytosis	Griseofulvin is identified as a treatment for dermatophyte infections, later becoming a standard oral therapy for tinea.	Europe
1911	Discovery	Monosporium apiospermum	Mycetoma	Saccardo isolates the white-grain mycetoma fungus and names it Monosporium apiospermum.	International
1911–1913	Classification	Paracoccidioides brasiliensis	Paracoccidioidomycosis	Splendore differentiates the fungus from Coccidioides immitis and assigns it the name Zymonema brasiliensis, establishing it as a distinct species.	Brazil

1923	Classification	Candida albicans	Candidiasis	Berkhout transfers the organism to the genus Candida, establishing the nomenclature still in use today.	International
1927	Classification	Paracoccidioides brasiliensis	Paracoccidioidomycosis	Souza Campos and Almeida definitively separate the fungus from Coccidioides immitis and name it Paracoccidioides brasiliensis. In 1930, Fonseca Filho and A. Leão prepare antigen for cutaneous testing from culture filtrates.	Brazil
1931	Discovery	Lacazia loboi	Lacaziosis	Jorge Lobo describes the first human case of lacaziosis in an indigenous person from the Amazonas region of Brazil. The patient presents keloid-like lesions without lymphangitis or systemic dissemination; Lobo considers the condition a variety of paracoccidioidomycosis and names it blastomicosis queloideana.	Brazil
1931	Research	Paracoccidioides brasiliensis	Paracoccidioidomycosis	Argentine mycologist Pablo Negroni mentions four cases of the mycosis in his doctoral thesis, having confused it with C. immitis. He describes the in vitro conversion from the mycelial to the yeast phase, and in 1934 identifies the first case of paracoccidioidomycosis in Argentina.	Argentina
1933	Research	Histoplasma capsulatum	Histoplasmosis	W. De Monbrum confirms the fungal nature of Histoplasma capsulatum in the United States by culturing the fungus from clinical materials and reproducing the disease in animals, corroborating Koch's postulates and confirming the dimorphic nature of the organism.	United States
1934	Classification	Trichophyton, Microsporum, Epidermophyton	Dermatophytosis	Emmons revises dermatophyte classification, grouping them into three genera — Trichophyton, Microsporum, and Epidermophyton — using morphological and nutritional criteria. This taxonomy remains valid until the introduction of griseofulvin as a clinical reference point.	United States
1936	Discovery	Fonsecaea	Chromoblastomycosis	Argentine mycologist Pablo Negroni studies the first Argentine case of chromoblastomycosis and proposes the genus Fonsecaea to classify the causative dematiaceous fungi.	Argentina
1936	Research	Coccidioides immitis	Coccidioidomycosis	Ernest Dickson and his student Myrnie Gifford establish that the self-limited illness known as San Joaquin fever, Desert fever, or Valley fever — previously considered a separate entity — is in fact the primary form of coccidioidomycosis caused by C. immitis, unifying what had been seen as distinct clinical entities.	United States
1938	Research	Lacazia loboi	Lacaziosis	Fialho reports a second patient from the Amazonas with tumoral lesions of the right ear pavilion, and concludes based on histopathological similarity that Lobo's disease differs from paracoccidioidomycosis, naming it enfermedad de Jorge Lobo.	Brazil

1954	Organization	—	—	The International Society for Human and Animal Mycology (ISHAM) is founded at the VII International Congress of Botany with 150 members, with American mycologist Libero Ajello as co-founder and first president. ISHAM becomes the leading international body representing professionals working with fungal diseases and pathogenic fungi, subsequently affiliating over thirty national medical mycology associations and becoming a recognized non-governmental affiliate of the World Health Organisation.	International
1955	Treatment	—	Invasive fungal infection	Amphotericin B is developed, becoming the first antifungal agent and establishing itself as the gold standard for treating serious invasive fungal infections (IFI). Despite its efficacy, its significant toxicity profile drives the pharmaceutical industry to develop safer antifungal families in subsequent decades.	United States
1956	Classification	—	Mucormycosis	Chester Emmons creates the term phycomycosis to include infections caused by fungi traditionally placed in the class Phycomycetes, encompassing infections produced by fungi of the orders Mucorales and Entomophthorales.

1965	Publication	Aspergillus	—	Raper and Thom publish A Manual of Aspergilli, describing 18 groups, 132 species, and 18 varieties. Currently, molecular methods allow differentiation of pathologically important species within the section Fumigati, some of which show high minimum inhibitory concentration values against amphotericin B, voriconazole, and itraconazole.	United States
1966	Discovery	Paracoccidioides brasiliensis	Paracoccidioidomycosis	Argentine mycologist Pablo Negroni isolates P. brasiliensis from soil in the Roque Sáenz Peña area of Chaco province, Argentina, establishing a definitive environmental reservoir for the fungus, which had previously been considered sterile in culture.

1968	Classification	Cryptococcus neoformans	Cryptococcosis	Wilson, Bennett, and Bailey identify the fourth serotype D and the hybrid AD of C. neoformans through agglutination and absorption studies with anti-cryptococcal sera, completing the four-serotype classification framework initiated by Evans in 1950.	United States
1969	Classification	—	—	American ecologist Robert Whittaker proposes assigning fungi their own kingdom, separating them from plants and animals. This classification recognizes the unique heterotrophic, absorptive nutritional strategy of fungi and becomes the foundation for subsequent taxonomic frameworks, including the five-kingdom scheme later refined by Margulis and Schwartz in 1988.	United States
1970	Classification	Exophiala werneckii	Tinea nigra	Von Arx, based on observation of conidial production from an anélide, reclassifies the fungus into the genus Exophiala as Exophiala werneckii.	International
1970	Treatment	—	Chromoblastomycosis	González Ochoa reports the cure of chromoblastomycosis using high doses of 5-fluorocytosine, marking an important advance in antifungal therapy for this difficult-to-treat infection.	Mexico
1972	Research	Blastomyces dermatitidis	Blastomycosis	An epidemic in Big Fork, Minnesota provides new knowledge about blastomycosis and the habitat of its causal agent, contributing to establishing the geographic distribution of the disease through autochthonous clinical case reporting.	United States
1973	Discovery	Talaromyces marneffei	Talaromycosis	The first case of natural human infection is recorded in an American missionary with Hodgkin's disease who had visited Southeast Asia, establishing the clinical profile of penicilliosis in an immunocompromised host.	United States
1974	Classification	—	Phaeohyphomycosis	L. Ajello coins the term phaeohyphomycosis to encompass diseases produced by different black fungi presenting in host tissues as dark yeasts, hyphae, or pseudohyphae — but not as sclerotic bodies or fumagoid cells characteristic of chromoblastomycosis. The term is accepted by the International Society for Human and Animal Mycology (ISHAM) and derives from the Greek phaios (dark), replacing earlier names such as micetoma, tinea nigra, and piedra negra.	United States
1975	Research	Lacazia loboi	Lacaziosis	Over one hundred cases are documented, all originating from countries with tropical climates in Central and South America, consolidating lobomycosis as a disease of the American tropics. The term lobomicosis is preferred over blastomicosis queloideana as lesions are not always keloid-like.	International
1975	Classification	Cryptococcus neoformans	Cryptococcosis	Kwon-Chung describes the complete life cycle of C. neoformans, naming the sexual phase of serotypes A and D Filobasidiella neoformans and the sexual phase of serotypes B and C F. bacillispora.	International
1976	Discovery	Saksenaea vasiformis	Mucormycosis	Saksenaea vasiformis is isolated from a patient who received glucocorticoids following a traffic accident, adding a new species to the growing list of mucormycosis agents.	International
1978	Treatment	Paracoccidioides brasiliensis	Paracoccidioidomycosis	Ketoconazole is introduced for the treatment of paracoccidioidomycosis, producing excellent results over one year of administration with a low relapse rate and good tolerability, representing a significant advance over amphotericin B.	International
1979	Research	Aspergillus fumigatus	Aspergillosis	Reiss and Lehmann first describe the diagnostic value of serum galactomannan — a polysaccharide cell wall component released by Aspergillus during active growth — for the diagnosis of invasive pulmonary aspergillosis, establishing the conceptual basis for non-culture-based antigen detection in fungal diagnostics. This approach would take over two decades to reach routine clinical application but represents a paradigm shift toward biomarker-based diagnosis of invasive fungal infections.	International
1980	Research	Paracoccidioides brasiliensis	Paracoccidioidomycosis	Standard and Kaufman describe the immunological method for identifying the mycelial form of P. brasiliensis. Extraction of a soluble cell-free antigen (exoantigen) allows detection of specific precipitation bands by immunodiffusion, providing a reliable diagnostic tool for the disease.	International
1981	Research	Pneumocystis jirovecii	Pneumocystis pneumonia	Pneumocystis pneumonia is recognised as the first opportunistic infection described in association with HIV, and is subsequently categorised as an AIDS-defining illness, dramatically raising the clinical profile of the infection worldwide.	United States
1982	Treatment	Paracoccidioides brasiliensis	Paracoccidioidomycosis	Itraconazole is introduced and becomes the drug of choice for paracoccidioidomycosis, effective in approximately 95% of cases at doses of 100–300 mg/day for six months, with a low relapse rate and good general tolerability.	International
1984	Classification	Hortaea werneckii	Tinea nigra	Nishimura and Miyaji propose the genus Hortae based on electron microscopy observations of conidiogenic sympodial cells and anélides. McGinnis et al. subsequently suggest the genus Phaeoannellomyces as an alternative, reflecting ongoing taxonomic debate over the correct placement of the tinea nigra agent.	International
1984	Research	Blastomyces dermatitidis	Blastomycosis	An epidemic in Eagle River, Wisconsin further advances understanding of blastomycosis epidemiology and the environmental conditions associated with B. dermatitidis, consolidating the picture of the disease's distribution in the upper Midwest.	United States
c. 1980	Discovery	Malassezia sympodialis	—	Based on DNA-GC content hybridization studies conducted in the late 1980s, Malassezia sympodialis is defined as a new species within the genus, expanding understanding of intrageneric diversity.	International
c. 1980s	Research	Talaromyces marneffei	Talaromycosis	A notable increase in human cases begins in the region from the second half of the 1980s, coinciding with the HIV/AIDS pandemic in Southeast Asia. The endemic area expands toward the Indian subcontinent, and penicilliosis becomes the third most serious AIDS-associated infection in Thailand, surpassed only by tuberculosis and cryptococcosis.	Southeast Asia
1988	Classification	Pneumocystis jirovecii	Pneumocystis pneumonia	DNA analysis demonstrates that Pneumocystis is a fungus rather than a protozoan, shifting its nomenclature from the International Code of Zoological Nomenclature to the International Code of Botanical Nomenclature and opening the path to formal species-level renaming.	International
1989	Treatment	Pneumocystis jirovecii	Pneumocystis pneumonia	The Centers for Disease Control and Prevention (CDC) formally recommends trimethoprim-sulfamethoxazole (TMP-SMX) prophylaxis for HIV-infected patients with CD4 cell counts below 200/mm³, establishing the first evidence-based antifungal prophylaxis guideline for immunocompromised patients. A landmark 1992 randomised controlled trial by the Dutch AIDS Treatment Group subsequently confirms that daily TMP-SMX is more effective than monthly aerosolized pentamidine as primary prophylaxis, making TMP-SMX the standard of care and dramatically reducing Pneumocystis pneumonia mortality in the AIDS epidemic.	United States, International
1990	Treatment	—	—	Fluconazole is introduced as a new-generation azole antifungal, offering broader spectrum coverage and an improved safety profile compared to earlier azoles such as ketoconazole. Over the following two decades it becomes one of the most widely used antifungals globally.	International
1990	Research	Cryptococcus gattii	Cryptococcosis	Ellis and Pfeiffer identify the ecological niche of C. neoformans var. gattii as certain eucalyptus species, including Eucalyptus camaldulensis and E. tereticornis, explaining the geographic distribution of this variety.	Australia
c. 1990	Research	Malassezia	—	Molecular techniques, particularly sequencing of the rADN region, begin to be applied to Malassezia systematics from around 1990 onward, enabling significant advances in species-level identification within the genus and superseding ambiguous phenotypic tests such as catalase, β-glucosidase reactions, and lipid utilization profiles.	International
1992	Treatment	Trichophyton, Epidermophyton	Dermatophytosis, Onychomycosis	Terbinafine, a synthetic allylamine antifungal developed by Sandoz Pharmaceuticals, receives FDA approval in topical form and subsequently as an oral agent in 1996, becoming the gold standard treatment for dermatophyte infections including onychomycosis. Unlike azoles, terbinafine acts early in the ergosterol biosynthesis pathway by selectively inhibiting squalene epoxidase, causing toxic accumulation of squalene and fungal cell death. Its high cure rates, favourable tolerability, and fungicidal mechanism make it the preferred oral treatment for nail dermatophytosis, capturing approximately 80% of the global onychomycosis market.	United States
1996	Classification	Malassezia	—	Guého and collaborators revise the genus Malassezia using morphological, physiological, ultrastructural, and molecular biology techniques, expanding it to include seven species. The addition of molecular methods to fungal systematics elevates the number of recognized species in the genus, which currently reaches fourteen.	International
1998–2004	Outbreak	Sporothrix schenckii	Sporotrichosis	The Oswaldo Cruz Foundation in Rio de Janeiro diagnoses 1,503 cats, 64 dogs, and 756 human cases of sporotrichosis, representing the largest documented epidemic of zoonotic sporotrichosis transmitted via contact with domestic cats. Over 80% of feline and human cases have clear antecedents of contact with cats through bites and scratches; Sporothrix is isolated from cutaneous lesions in 100% of sick cats and from oral swabs in 66.2% of cases, establishing cat-to-human transmission as the dominant route in urban settings.	Brazil
1998	Research	Aspergillus fumigatus	Aspergillosis	Azole-resistant Aspergillus fumigatus strains bearing mutations in the cyp51A gene — including M220I isolated from a Swedish patient — begin to be documented in clinical settings, marking the emergence of acquired azole resistance in this major pathogen. These mutations arise in patients receiving long-term azole therapy, particularly for chronic pulmonary aspergillosis, and involve a growing range of substitutions at codons G54, G138, P216, M220, and G448.	International
1999	Discovery	Lacazia loboi	Lacaziosis	Taborda and collaborators identify the fungus as the etiological agent of lacaziosis in dolphins off the coasts of Florida and Suriname, establishing a zoonotic reservoir and renaming the genus Lacazia in honor of Jorge Lobo.	United States, Suriname
1999	Classification	Cryptococcus neoformans	Cryptococcosis	Franzot and collaborators describe a new variety for serotype A — C. neoformans var. grubii — and restrict the variety neoformans to serotype D isolates only.	International
1999	Outbreak	Cryptococcus gattii	Cryptococcosis	An epidemic of cryptococcosis due to C. gattii affecting both animals and humans is described in the southwest of Canada and the east coast of Vancouver Island. Exhaustive environmental sampling detects the pathogen in tree hollows, soil detritus, and other materials, indicating that C. gattii can establish itself in temperate zones beyond its previously known tropical and subtropical range in Africa, Europe, Australia, and the Americas. Climate change and land use are proposed as explanatory factors for this geographic expansion.	Canada, International
2001	Treatment	—	Invasive candidiasis, Aspergillosis	Caspofungin, developed by Merck Laboratories, receives FDA approval as the first member of the echinocandin class of antifungals — a new mechanism of action that inhibits β-1,3-D-glucan synthase, disrupting fungal cell wall biosynthesis. Unlike polyenes and azoles, echinocandins target a component absent in mammalian cells, offering improved safety profiles. Micafungin and anidulafungin follow in 2005 and 2006 respectively, establishing echinocandins as the preferred first-line treatment for invasive candidiasis.	United States
2002	Classification	Pneumocystis jirovecii	Pneumocystis pneumonia	Stringer et al. publish a landmark paper in Emerging Infectious Diseases disseminating the name Pneumocystis jirovecii Frenkel 1999 for the human pathogen, replacing Pneumocystis carinii. The renaming honours Czech parasitologist Otto Jirovec and reflects molecular evidence that Pneumocystis organisms in different host species are genetically distinct, with each species being host-specific.	International
2002	Treatment	—	Aspergillosis, Invasive candidiasis	Voriconazole, developed by Pfizer Pharmaceuticals, receives FDA and European approval as the first second-generation triazole antifungal. Structurally derived from fluconazole but with significantly broader spectrum, it demonstrates activity against Aspergillus species, Candida species including fluconazole-resistant strains, Fusarium, and Scedosporium. It becomes the standard of care for invasive aspergillosis and represents a major advance over first-generation azoles in treating serious mould infections.	United States
2003	Research	Cryptococcus gattii	Cryptococcosis	The genome sequencing of C. gattii is completed, following its establishment as an independent species through molecular studies, enabling deeper understanding of its pathogenicity and epidemiology.	International
2003	Research	Aspergillus	Aspergillosis	The FDA clears the Platelia Aspergillus EIA (Bio-Rad Laboratories), the first commercially available immunoenzymatic assay for detection of circulating galactomannan antigen in serum, for diagnostic use in invasive aspergillosis. The test can detect galactomannan 7–14 days before other diagnostic modalities become apparent, enabling preemptive antifungal therapy before life-threatening infection develops, and becomes a standard microbiological criterion in EORTC/MSG diagnostic guidelines for invasive fungal infections.	United States
2004	Research	—	—	Commercial MALDI-TOF mass spectrometry platforms begin to be released for clinical microbiology identification, initially adapted to bacteria and subsequently extended to yeasts and filamentous fungi. By generating highly specific protein spectra that function as molecular barcodes, MALDI-TOF MS enables species-level identification of fungal pathogens within minutes — a dramatic reduction compared to traditional culture-based methods requiring days to weeks. The technology revolutionises clinical mycology laboratory practice, significantly reducing turnaround times and enabling identification of cryptic species complexes previously indistinguishable by morphology alone.	International
2006	Classification	—	—	James et al. publish a landmark phylogenetic analysis of six genes from across the kingdom Fungi, producing major revisions in fungal systematics. The study advances the concept of phylogenetic species recognition, establishing evolutionary relationships among diverse fungal microorganisms and demonstrating that many species previously considered simple morphotypes are in fact species complexes, often distinguishable only at the molecular level — a finding with direct clinical implications for antifungal susceptibility.	International
2007	Research	Aspergillus fumigatus	Aspergillosis	Mellado and collaborators identify a novel pan-azole resistance mechanism in A. fumigatus driven by a tandem repeat of 34 base pairs in the promoter of the cyp51A gene combined with the L98H substitution (TR34/L98H), later found to originate from environmental exposure to agricultural azole fungicides rather than from clinical azole use. This environmentally-driven resistance route, subsequently identified across Europe, Asia, and Africa in both environmental and clinical samples, represents a major new threat to antifungal therapy and demonstrates that agricultural fungicide use has direct consequences for human medicine.	Netherlands
2009	Discovery	Candida auris	Candidiasis	Candida auris is first described after isolation from the external ear canal of a patient in Tokyo, Japan, representing a novel multidrug-resistant yeast species. Subsequent genomic analyses reveal that C. auris emerged simultaneously across multiple continents as five genetically distinct clades, suggesting independent emergence events rather than a single origin. Its resistance to multiple antifungal classes, ability to persist in healthcare environments, capacity to spread between patients, and tendency to be misidentified by routine laboratory methods make it a significant global public health threat. In 2016, the CDC issues a clinical alert to healthcare facilities worldwide warning of its international emergence.	Japan, International
2010	Classification	Fonsecaea rubica	Chromoblastomycosis	Molecular biology methods describe Fonsecaea rubica, a new species morphologically similar to F. pedrosoi and F. monophora, further expanding the taxonomic complexity of chromoblastomycosis agents.	International
2021	Outbreak	Rhizopus arrhizus	Mucormycosis	During the second wave of the COVID-19 pandemic in India, over 45,000 cases and 4,300 deaths from COVID-19-associated mucormycosis (CAM) are reported between April and July 2021, representing an unprecedented epidemic of the disease popularly known as "black fungus." The outbreak is driven by a convergence of factors including uncontrolled diabetes — present in 94% of cases — excessive and inappropriate corticosteroid use for COVID-19 treatment, and prolonged intensive care unit stays. India contributes approximately 71% of global CAM cases, and the Indian government declares mucormycosis a notifiable disease under the Epidemic Diseases Act of 1897. The epidemic highlights the role of immunosuppression as the dominant risk factor for mucormycosis and raises global awareness of the intersection between viral pandemics and invasive fungal infections.	India
2022	Publication	—	—	The World Health Organization publishes the first-ever Fungal Priority Pathogens List (FPPL), cataloguing 19 fungal pathogens classified into critical, high, and medium priority groups based on mortality, antifungal resistance, annual incidence, global distribution, and unmet research and development needs. Critical priority pathogens include Cryptococcus neoformans, Candida auris, Aspergillus fumigatus, and Candida albicans. The list represents the first global systematic effort to prioritize fungal pathogens and drive research and public health responses, modelled on the WHO bacterial priority pathogen list published in 2017, and comes amid rising antifungal resistance and an expanding global immunocompromised population.

Feedback and comments

Feedback for the timeline can be provided at the following places:

• FIXME

What the timeline is still missing

• Page numbers: The majority of rows citing Landaburu & Mujica (2016) still contain placeholders. These should be filled in by cross-referencing the physical book before the timeline is submitted for review.

• Single-source bias: A large portion of the timeline is based on a single Spanish-language textbook (Landaburu & Mujica 2016). While this source is authoritative for the Argentine and Latin American mycological tradition, it may underrepresent developments from Anglophone, European, and Asian mycology. Future enrichment should draw on sources such as Larone's Medically Important Fungi, Kwon-Chung & Bennett's Medical Mycology, and peer-reviewed journals including Medical Mycology, Journal of Fungi, and Mycoses.

• Antifungal resistance beyond Aspergillus: The timeline covers azole resistance in Aspergillus fumigatus (1998, 2007) and multidrug resistance in Candida auris (2009), but does not yet address fluconazole resistance in Candida glabrata and Candida krusei, or the emergence of echinocandin-resistant Candida strains in clinical settings.

• Dermatophyte terbinafine resistance: The recent global emergence of terbinafine-resistant Trichophyton indotineae, reported from the Indian subcontinent from around 2016 onward and subsequently in Europe and North America, represents a significant new clinical challenge not yet covered in the timeline.

• Molecular diagnostics beyond MALDI-TOF: PCR-based and next-generation sequencing (NGS) approaches for fungal diagnosis, including panfungal PCR and metagenomic sequencing, are absent from the timeline despite representing a major recent development in clinical mycology.

• Fungal infections and climate change: The expanding geographic range of endemic mycoses such as coccidioidomycosis and histoplasmosis in association with climate change is an emerging topic not yet represented.

• Antifungal drug pipeline: Novel antifungal agents currently in late-stage clinical trials — including olorofim (first-in-class dihydroorotate dehydrogenase inhibitor), ibrexafungerp, and rezafungin — are absent and warrant inclusion once approved.

• African histoplasmosis and less-covered endemic mycoses: Histoplasma capsulatum var. duboisii (African histoplasmosis), Lacazia loboi veterinary cases beyond dolphins, and Emmonsia species are underrepresented or absent.

• Veterinary mycology: With the exception of the Lacazia loboi dolphin cases (1999) and the Sporothrix cat-to-human epidemic (1998–2004), veterinary mycology is largely absent from the timeline.
