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.
Dothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1,300 genera and over 19,000 known species. Wijayawardene et al. in 2020 added more orders to the class.
The Clavicipitaceae are a family of fungi within the order Hypocreales. A 2008 estimate placed 43 genera in the family, but a study in 2020 has increased this number to 50.
Stachybotrys is a genus of molds, hyphomycetes or asexually reproducing, filamentous fungi, now placed in the family Stachybotryaceae. The genus was erected by August Carl Joseph Corda in 1837. Historically, it was considered closely related to the genus Memnoniella, because the spores are produced in slimy heads rather than in dry chains. Recently, the synonymy of the two genera is generally accepted. Most Stachybotrys species inhabit materials rich in cellulose. The genus has a widespread distribution and contained about 50 species in 2008. There are 88 records of Stachybotrys on Species Fungorum, of which 33 species have DNA sequence data in GenBank. Species in the genus are commonly found in soil, plant litter and air and a few species have been found from damp paper, cotton, linen, cellulose-based building materials water-damaged indoor buildings, and air ducts from both aquatic and terrestrial habitats.
Hypocreomycetidae is a subclass of sac fungi.
Metarhizium is a genus of entomopathogenic fungi in the Clavicipitaceae family. With the advent of genetic profiling, placing these fungi in proper taxa has now become possible. Most turn out to be the asexual forms (anamorphs) of fungi in the phylum Ascomycota, including Metacordyceps spp.
The Halosphaeriaceae are a family of fungi in the Sordariomycetes class, subclass Hypocreomycetidae. Halosphaeriaceae is the family with the largest number of marine fungi with a few species are from freshwater and terrestrial habitats.
Eutypa is a genus of fungi in the family Diatrypaceae. The widespread genus was estimated to contain 32 species in 2008, and then 68 by 2023. Anamorphic forms include the genera Libertella and Cytosporina. The genus was circumscribed in 1863 by the French mycologists and brothers Louis and Charles Tulasne.
Annulohypoxylon, sometimes called cramp balls, is a genus of fungi in the family Xylariaceae. The 27 species in the genus have a collectively widespread distribution.
Camillea is a genus of fungi in the family Graphostromataceae. Collectively, the 40+ species in the genus have a widespread distribution, but are especially prevalent in tropical areas. Fruit bodies of Camillea species tend to be cylindrical in shape. The genus was originally circumscribed by Swedish mycologist Elias Fries in his 1849 work Summa vegetabilium Scandinaviae.
Roussoëlla is a genus of fungi in the family Roussoellaceae. The genus is characterized by two-celled ascospores, unitunicate asci with a small spherical apical ring that stains slightly blue with Melzer's reagent, and stromata with several perithecia. The genus was circumscribed by Italian mycologist Pier Andrea Saccardo in 1888, with Roussoella nitidula assigned as the type species. The generic name honours Marietta Hannon Rousseau, (1850–1926), who was a Belgian mycologist and taxonomist.
The Boliniaceae are a family of fungi in the Boliniales order. The family consisted of seven genera and 40 species in 2008. A new study found more genera and species in 2020.
Bertia is a genus of fungi within the Bertiaceae family, and Hypocreomycetidae subclass.
The Coniochaeta are a genus of pleomorphic yeasts of the order Coniochaetales and are pathogens of trees. Some species have also been found to form endophytic associations within plants in which they live inside plant tissues but do not actually harm the organism. They can take the form of pink to brown colonies, hyphae, conidiophores or sclerotia. In 2013, the Lecythophora were merged with the Coniochaeta, following suggestions by Ziauddin Khan et al.
Gliomastix is a genus of fungi belonging to the family Bionectriaceae.
Cordyceps locustiphila is the basionym and teleomorph of the fungi Beauveria locustiphila, a species of fungus in the family Cordycipitaceae. and is a species within the genus Cordyceps. It was originally described in by Henn in 1904. C. locustiphila is an entomopathogen and obligate parasite of the grasshopper species within the genus Colpolopha or Tropidacris, and as such is endemic to South America. The scientific name is derived from its close relationship with its host, being named after locusts. The fungi was renamed to Beauveria locustiphila in 2017 following research into the family Cordycipitaceae. Following the loss of the species type specimen, new studies were conducted that now recommend that the fungi be divided into 3 species. C. locustiphila, C. diapheromeriphila, and C. acridophila.
Fuscosporellales is an order of fungi within the phylum of Ascomycota and in the class Sordariomycetes and subdivision of Pezizomycotina.
Pisorisporiales is an order of fungi within the phylum of Ascomycota and in the class Sordariomycetes and subdivision of Pezizomycotina and also its own subclass Pisorisporiomycetidae.
