Arachnomyces is a genus of cleistothecial ascomycete fungi described in 1902, [1] of which the anamorph (asexual) stage is the genus Onychocola. [2] 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.

Phylogeny

The placement of Arachnomyces has changed multiple times due to its morphological similarities to members of different families. When first described in 1902, it was included in the old family Perisporiaceae. Later it was considered as part of Onygenaceae, then it was placed within the Gymnoascaceae in 1996. Thanks to phylogenetic analyses Arachnomyces is currently recognized as a distinct monophyletic lineage, composing its own family Arachnomycetaceae and order Arachnomycetales within the class Eurotiomycetes.

<span class="mw-page-title-main">Eurotiomycetes</span> Class of fungi

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".

<span class="mw-page-title-main">Hypocreales</span> Order of fungi

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.

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.

<i>Neoscytalidium dimidiatum</i> Species of fungus

Neoscytalidium dimidiatum was first described in 1933 as Hendersonula toruloidea from diseased orchard trees in Egypt. Decades later, it was determined to be a causative agent of human dermatomycosis-like infections and foot infections predominantly in tropical areas; however the fungus is considered to be widespread. A newer name, Scytalidium dimidiatum, was applied to a synanamorph of Nattrassia mangiferae, otherwise known as Neofusicoccum mangiferae. Substantial confusion has arisen in the literature on this fungus resulting from the use of multiple different names including Torula dimidiata, Fusicoccum dimidiatum, Scytalidium dimidiatum, and Hendersonula toruloidea. Additionally, Scytalidium lignicola and Scytalidium lignicolum are often considered earlier names of N. dimidiatum.

<i>Keratinophyton durum</i> Species of fungus

Keratinophyton durum is a keratinophilic fungus, that grows on keratin found in decomposing or shed animal hair and bird feathers. Various studies conducted in Canada, Japan, India, Spain, Poland, Ivory Coast and Iraq have isolated this fungus from decomposing animal hair and bird feathers using SDA and hair-bait technique. Presence of fungus in soil sediments and their ability to decompose hairs make them a potential human pathogen.

Myriodontium keratinophilum is a fungus widespread in nature, most abundantly found in keratin-rich environments such as feathers, nails and hair. Despite its ability to colonize keratinous surfaces of human body, the species has been known to be non-pathogenic in man and is phylogentically distant to other human pathogenic species, such as anthropophilic dermatophytes. However, its occasional isolation from clinical specimens along with its keratinolytic properties suggest the possibility it may contribute to disease.

Oidiodendron is a genus of fungi in the family Myxotrichaceae. It has 26 species. The genus was circumscribed by Norwegian forester Håkon Robak in 1932, with Oidiodendron fuscum assigned as the type species. The species is now known as Oidiodendron tenuissimum.

Monodictys is a genus of fungi of uncertain familial and ordinal placement in the class Ascomycetes. The genus was circumscribed by Welsh-born Canadian mycologist Stanley Hughes in 1956. He assigned Monodictys putredinis as the type species.
