The Chaetothyriales are an order of ascomycetous fungi in the class Eurotiomycetes and within the subclass Chaetothyriomycetidae. [1] The order was circumscribed in 1987 by mycologist Margaret Elizabeth Barr-Bigelow. [2]
As of October 2021 [update] , Species Fungorum includes 9 families, 97 genera, and 691 species in the Chaetothyriales. [3] The following list shows the families, genera, and number of species in the Chaetothyriales, adapted from a recent (2020) taxonomic and nomenclatural review of the order. [4]
Several genera have been included in the Chaetothyriales although their familial placement is unknown. These include:
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".
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 Hysteriaceae are a taxonomic family of fungi and the only extant family of the order Hysteriales. Members of the Hysteriaceae are defined by the possession of a sexual structure called the hysterothecium, an elongated structure that opens by a longitudinal slit and releases sexually produced spores. The family is widely distributed, with many species found in temperate regions, and most are saprobic on wood and bark, although a few are parasitic on plants.
The Phaeosphaeriaceae are a family of fungi in the order Pleosporales. Species in the family have a cosmopolitan distribution, and are generally nectrotrophic or saprobic on a wide range of plants.
The Pleomassariaceae are a family of fungi in the order Pleosporales. Taxa have a widespread distribution in both temperate and tropical regions, and are saprobic or necrotrophic on wood, bark, and other herbaceous material. The genus was circumscribed by mycologist Margaret Elizabeth Barr-Bigelow in 1979.
The Lecanorales are an order of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The order contains 26 families, 269 genera, and 5695 species.
The Dactylosporaceae or Sclerococcaceae are a family of lichen-forming fungi in the class Eurotiomycetes. It is the only family of the order Sclerococcales and subclass Sclerococcomycetidae.
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.
Verrucariales is an order of ascomycetous fungi within the subclass Chaetothyriomycetidae of the class Eurotiomycetes. Although most of the Verrucariales are lichenised, the family Sarcopyreniaceae consists of 11 species of lichenicolous (lichen-dwelling) fungi.
Verrucariaceae is a family of lichens and a few non-lichenised fungi in the order Verrucariales. The lichens have a wide variety of thallus forms, from crustose (crust-like) to foliose (bushy) and squamulose (scaly). Most of them grow on land, some in freshwater and a few in the sea. Many are free-living but there are some species that are parasites on other lichens, while one marine species always lives together with a leafy green alga.
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 Trichosphaeriales are an order of sac fungi. It is monotypic, and consists of the single family, the Trichosphaeriaceae. In 2017, the family of Trichosphaeriaceae was placed in Diaporthomycetidae families incertae sedis, which was accepted by Wijayawardene et al. (2018), and Wijayawardene et al. 2020. The order of Trichosphaeriales was also unplaced. They are generally saprobic and pathogenic on plants, commonly isolated from herbivore dung.
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.
Cordieritidaceae is a family of fungi in the order Cyttariales. Species in this family are saprobes or lichenicolous.
Epibryon is a genus of fungi, and the sole genus in the monogeneric family Epibryaceae. It has about 40 species. Many of the species grow parasitically on bryophytes. The genus was circumscribed by mycologist Peter Döbbeler in 1978; the family by Soili Stenroos and Cécile Gueidan in 2014.
Celotheliaceae is a family of fungi in the monotypic order Phaeomoniellales. It contains 27 species of crustose lichens with thalli that are more or less immersed in tree bark.
Minutoexcipula is a genus of lichenicolous (lichen-dwelling) fungi of uncertain familial placement in the order Chaetothyriales. It has eight species. The genus was circumscribed in 1994 by M. Violeta Atienza Tamarit and David Leslie Hawksworth, with Minutoexcipula tuckerae assigned as the type species. The genus is characterized both by its black convex sporodochia-like conidiomata, as well as the well-differentiated exciple on these structures.
Léon Vouaux was a French priest, philologist and lichenologist. He was executed by German forces in the second month of the First World War. The Académie Française awarded him the Prix Saintour posthumously in 1915.
Conioscyphales is an order of freshwater and terrestrial fungi within the division Ascomycota. It is in the subclass Savoryellomycetidae and the class Sordariomycetes and the subdivision of Pezizomycotina.
