The Onygenaceae are a family of fungi in the Ascomycota, class Eurotiomycetes.
These are the genera that are in the Onygenaceae, according to a 2021 review of fungal classification. [2] Following the genus name is the taxonomic authority (those who first circumscribed the genus; standardized author abbreviations are used), year of publication, and the estimated number of species. [2]
Eurotiomycetes is a large class of ascomycetes with cleistothecial ascocarps within the subphylum Pezizomycotina, currently containing around 3810 species according to the Catalogue of Life. It is the third largest lichenized class, with more than 1200 lichen species that are mostly bitunicate in the formation of asci. It contains most of the fungi previously known morphologically as "Plectomycetes".
The Eurotiales are an order of sac fungi, also known as the green and blue molds. It was circumscribed in 1980.
The Hypocreales are an order of fungi within the class Sordariomycetes. In 2008, it was estimated that it contained some 237 genera, and 2647 species in seven families. Since then, a considerable number of further taxa have been identified, including an additional family, the Stachybotryaceae. Wijayawardene et al. in 2020 added more families and genera to the order. According to the Catalog of Life, As of April 2021 the Hypocreales contains 6 families, 137 genera, and 1411 species. Hyde et al. (2020a) listed 14 families under Hypocreales, while, Wijayawardene et al. (2022) accepted 15 families in the order, where Cylindriaceae was additionally added. Earlier, Hyde et al. (2020a) had placed Cylindriaceae in class Xylariomycetidae. Samarakoon et al. (2022) agreed. Hence, Cylindriaceae should have been excluded from Hypocreales and placed in Xylariomycetidae. Xiao et al. (2022) recently introduced a new family Polycephalomycetaceae to Hypocreales.
Chrysosporium is a genus of hyaline hyphomycetes fungi in the family Onygenaceae.
The Pyronemataceae are a family of fungi in the order Pezizales. It is the largest family of the Pezizales, encompassing 75 genera and approximately 500 species. Phylogenetic analyses does not support the prior classifications of this family, and suggest that the family is not monophyletic as it is currently circumscribed.
The Microascaceae are a family of fungi in the class Sordariomycetes, subclass Hypocreomycetidae. The family was published by David Malloch in 1970, an emended description based on Everet Stanley Luttrell's original 1951 publication. Family was updated in 2020.
Microascus is a genus of fungi in the family Microascaceae.
The Bionectriaceae are a family of fungi in the order Hypocreales. A 2008 estimate places 35 genera and 281 species in the family. Species in the family tend to grow on plant material, including woody debris, while some species associate with algae, bryophytes, or other fungi.
Chlamydosauromyces punctatus is the sole species in the monotypic genus of fungi, Chlamydosauromyces in the family, Onygenaceae. It was found in the skin shed from frilled lizard. This fungus is mesophilic and digests hair. It reproduces both sexually and asexually. The fungus has so far not been reported to be pathogenic.
Polytolypa is a monotypic genus of fungus containing the single species Polytolypa hystricis. First classified in the Onygenaceae family, as of 2008 it is considered to be in the Ajellomycetaceae, although there is still uncertainty as to its phylogenetic relationships with other similar genera. This species is only known from a single specimen derived in the laboratory from a specimen of dung of the North American porcupine, Erethizon dorsatum, collected in Ontario, Canada. Polytolypa hystricis contains bioactive compounds that have antifungal activity.
Arachnomyces is a genus of cleistothecial ascomycete fungi described in 1902, of which the anamorph (asexual) stage is the genus Onychocola. Although morphologically similar to members of other families, the fungus now belongs to its own monotypic family Arachnomycetaceae, which is the only family in the monotypic order Arachnomycetales.
Scopinella is a genus of fungi in the Coronophorales order. The relationship of this taxon to other taxa within the order was unknown, It has been placed into the family of Ceratostomataceae.
Aphanoascus fulvescens is a mould fungus that behaves as a keratinophilic saprotroph and belongs to the Ascomycota. It is readily isolated from soil and dung containing keratin-rich tissues that have been separated from their animal hosts. This organism, distributed worldwide, is most commonly found in areas of temperate climate, in keeping with its optimal growth temperature of 28 °C (82 °F). While A. fulvescens is recognized as a geophilic fungal species, it is also a facultative opportunistic pathogen. Although it is not a dermatophyte, A. fulvescens has occasionally been shown to cause onychomycosis infections in humans. Its recognition in the laboratory is clinically important for correct diagnosis and treatment of human dermal infections.
Nannizziopsis vreisii is a keratinophilic microfungus in the Family Onygenaceae of the order Onygenales. Also included in this family are dematophytes and saprophytic species. While the ecology of N. vriessi is not well known, there has been several studies which identifies the Chrysosporium anamorph of N. vriesii as a causal agent of skin lesions in reptiles across several regions. This species is usually identified under a microscope by its white ascomata, and hyaline and globose ascospores. Like many other fungi, N. vreisii has a sexual and asexual state, the asexual states are classified as the genus Chryososporium, Malbranchea or Sporendonema.
Chrysosporium longisporum is a keratinophilic microfungus in the family Onygenaceae that causes skin infections in reptiles, producing hyaline, thin-walled, small, sessile conidia and colonies with a strong skunk-like odour.
Nannizziopsis arthrosporioides is a keratinophilic microfungus in the family Onygenaceae that causes skin infections in reptiles, producing hyaline, thin-walled, small, sessile conidia and colonies with a strong skunk-like odour. It is distinguished by the production of long arthroconidia.
Nannizziopsis draconii is a keratinophilic microfungus in the family Onygenaceae that causes skin infections in reptiles, producing hyaline, thin-walled, small, sessile conidia and colonies with a strong skunk-like odour.
Uncinocarpus reesii is a species of saprotrophic microfungi that grows in soil and on keratinous materials such as hair, feathers and skin. It was the first species to be designated as part of the genus Uncinocarpus, owing in part to its characteristic development of hooked (uncinate) appendages. As the closest non-pathogenic relative of Coccidioides immitis and C. posadasii, it has become a subject of research interest.
Dactylaria is a genus of fungi belonging to an unknown family. According to Wijayawardene et al. 2020; the genus was placed in order Helotiales genera incertae sedis.
