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".
Peltigera is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. Commonly known as the dog or pelt lichens, species of Peltigera are often terricolous, but can also occur on moss, trees, rocks, and many other substrates in many parts of the world.
Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (Ascomycota). It is the second-largest class of Ascomycota, with a worldwide distribution that mostly accommodates terrestrial based taxa, although several can also be found in aquatic habitats. Some are phytopathogens that can cause leaf, stem, and root diseases in a wide variety of hosts, while other genera can cause diseases in arthropods and mammals.
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.
Scutula is a genus of lichenicolous fungi in the family Ramalinaceae.
Gyalectales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 5 families, 15 genera and about 550 species.
The Xylariales are an order of fungi within the class Sordariomycetes, subdivision Pezizomycotina, division Ascomycota. It was the original order of the subclass Xylariomycetidae. Xylariales was circumscribed in 1932 by Swedish mycologist John Axel Nannfeldt, and Xylariomycetidae by Ove Erik Eriksson and Katarina Winka in 1997. In 2020, more families were added to the order.
Sordariomycetidae is a subclass of sac fungi.
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 Acarosporales are an order of fungi in the class Lecanoromycetes. Phylogenetic analyses conducted using the sequences of both the protein-coding gene RPB2 as well as nuclear ribosomal genes place this order within the subclass Acarosporomycetidae.
The Ostropomycetidae are a subclass of mostly lichen-forming fungi in the class Lecanoromycetes. The subclass was circumscribed in 2004 by Catherine Reeb, François M. Lutzoni, and Claude Roux. It contains ten orders and 36 families.
Lichinales is the sole order of ascomycete fungi in the class Lichinomycetes. It contains three families: Gloeoheppiaceae, Lichinaceae, and Peltulaceae. Most species are lichenized. Lichinales was proposed in 1986 by German lichenologists Aino Henssen and Burkhard Büdel. The class Lichinomycetes was created by Valérie Reeb, François Lutzoni and Claude Roux in 2004.
The Baeomycetales are an order of mostly lichen-forming fungi in the subclass Ostropomycetidae, in the class Lecanoromycetes. It contains 8 families, 33 genera and about 170 species. As a result of molecular phylogenetics research published in the late 2010s, several orders were folded into the Baeomycetales, resulting in a substantial increase in the number of taxa.
The Microascales are an order of fungi in the class Sordariomycetes, subclass Hypocreomycetidae. This is a relatively small order of mostly saprobic fungi that live in soil, rotting vegetation and dung. Some species are plant pathogens, such as Ceratocystis fimbriata, transmitted by beetles to living trees and causing cacao wilt and many other economically important diseases. Species in the genus Pseudallescheria are pathogenic to humans The order was circumscribed in 1980. Wijayawardene et al. in 2020 added more families and genera to the order.
Zwackhiomyces is a genus of lichenicolous fungi in the family Xanthopyreniaceae. The genus was circumscribed by Martin Grube and Josef Hafellner in 1990, with Zwackhiomyces coepulonus assigned as the type species.
The Candelariales are an order of fungi in the monotypic class Candelariomycetes. It contains the families Candelariaceae and Pycnoraceae. The order was circumscribed by Jolanta Miadlikowska, François Lutzoni, and Helge Thorsten Lumbsch as part of a comprehensive phylogenetic classification of the kingdom Fungi published in 2007. The class Candelariomycetes was created in 2018 by Hermann Voglmayr and Walter Jaklitsch.
Spirographa is a genus of parasitic fungi. It is the sole genus in the monotypic family Spirographaceae, belong to the order Ostropales. The genus was circumscribed by Alexander Zahlbruckner in 1903, with Spirographa spiralis later assigned as the type species in 1923. The family Spirographaceae was circumscribed by Adam Flakus, Javier Etayo and Jolanta Miadlikowska in 2019 on the basis of molecular phylogenetic analysis. They determined that genus Spirographa is an independent lineage in the Ostropales, sister to the clade containing the families Fissurinaceae, Gomphillaceae, and Graphidaceae.
The Ceratocystidaceae are a family of fungi in the class Sordariomycetes, subclass Hypocreomycetidae.
Hymenelia is a genus of lichen-forming fungi belonging to the family Hymeneliaceae.
