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.
The Chaetothyriales are an order of ascomycetous fungi in the class Eurotiomycetes and within the subclass Chaetothyriomycetidae. The order was circumscribed in 1987 by mycologist Margaret Elizabeth Barr-Bigelow.
The Botryosphaeriaceae are a family of sac fungi (Ascomycetes), which is the type representative of the order Botryosphaeriales. According to a 2008 estimate, the family contains 26 genera and over 1500 species. Members of this order include notable plant pathogens.
The Melanommataceae are a family of fungi in the order Pleosporales. Taxa are widespread in temperate and subtropical regions, and are saprobic on wood and bark.
The Didymosphaeriaceae are a family of fungi in the order Pleosporales. The family was erected by Anders Munk in 1953.
The Collemataceae are a lichenized family of fungi in the order Peltigerales. The family contains ten genera and about 325 species. The family has a widespread distribution.
The Sphaerophoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution, especially in southern temperate regions. Sphaerophoraceae was circumscribed by mycologist Elias Magnus Fries in 1831.
The Acarosporaceae are a family of fungi in the order Acarosporales. Members of this family have a widespread distribution, and are mostly lichenized with green algae. According to a 2021 estimate, the family contains 11 genera and about 260 species. The family is characterised by a hamathecium formed of paraphysoids.
The Ostropales are an order of fungi in the class Lecanoromycetes. The order was circumscribed by Swedish botanist John Axel Nannfeldt in 1932. The order contains 4 families and 46 genera, including 6 genera of uncertain familial placement.
The Coccotremataceae are a family of lichen-forming fungi in the order Pertusariales. Species in this widely distributed family grow on bark or rocks, especially in maritime regions.
Herpotrichiellaceae is a family of ascomycetous fungi within the order Chaetothyriales and within the class Eurotiomycetes. It contains 16 genera and about 270 species. The type genus of the family, Herpotrichiella, is now synonymous with Capronia.
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.
The Tubeufiaceae are a family of fungi in the order Tubeufiales of the class Dothideomycetes. The family was circumscribed in 1979 by mycologist Margaret Elizabeth Barr-Bigelow.
The Asterinaceae are a family of fungi in the class Asterinales.
Xanthopyreniaceae is a family of lichen-forming fungi in the order Collemopsidiales. The family was circumscribed by lichenologist Alexander Zahlbruckner in 1926.
The Onygenaceae are a family of fungi in the Ascomycota, class Eurotiomycetes.
The Arctomiaceae are a family of lichenized fungi in the Ascomycota, class Baeomycetales. The family was named by Theodor Magnus Fries in 1861, with Arctomia as the type genus. Species in this family are found in arctic and subarctic habitats, usually associated with bryophytes.
The Nitschkiaceae are a family of fungi in the Ascomycota, order Coronophorales. Species in the family are mostly saprobic on wood, although some grow on lichens.
Trichotheliaceae is a family of lichen-forming fungi in the order Gyalectales. The family was circumscribed by Friedrich von Schilling and Friedrich August Georg Bitter in 1927.
Opegraphaceae is a family of lichen-forming and lichenicolous fungi in the order Arthoniales. It was originally proposed by German lichenologist Ernst Stizenberger in 1862. It fell into disuse, but was resurrected in a molecular phylogenetic study of the order Arthoniales published in 2010. It now includes taxa that were previously referred to the family Roccellaceae, its sister group.
