The order Sordariales is one of the most diverse taxonomic groups within the Sordariomycetes.
Gyalectales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 5 families, 15 genera and about 550 species.
Arthoniomycetes are a class of ascomycete fungi. It includes two orders: Arthoniales and Lichenostigmatales. Most of the taxa in these orders are tropical and subtropical lichens.
The Arthoniales is the second largest orders of mainly crustose lichens, but fruticose lichens are present as well. The order contains around 1500 species, while the largest order with lichenized fungi, the Lecanorales, contains more than 14000 species.
Lichinomycetes are a class of ascomycete fungi. It includes the single order Lichinales. Most species are lichenized. The class was circumscribed in 2004.
Geoglossaceae is a family of fungi in the order Geoglossales, class Geoglossomycetes. These fungi are broadly known as earth tongues. The ascocarps of most species in the family Geoglossaceae are terrestrial and are generally small, dark in color, and club-shaped with a height of 2–8 cm. The ascospores are typically light-brown to dark-brown and are often multiseptate. Other species of fungi have been known to parasitize ascocarps. The use of a compound microscope is needed for accurate identification.
The Inocybaceae are a family of fungi in the order Agaricales. Members of this family have a widespread distribution in tropical and temperate areas.
The Acarosporaceae are a family of fungi in the order Acarosporales. Members of this family have a widespread distribution, and are 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 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 eight orders and 36 families.
Schizopelte is a genus of lichen-forming fungi in the family Opegraphaceae. The genus was circumscribed by Theodor Magnus Fries in 1875. It was resurrected for use in 2011 by Damien Ertz and Anders Tehler, who published a phylogenetic study of the order Arthoniales. In addition to the type species, S. californica, they included a former Hubbsia species, a former Llimonaea species, and a species new to science in the resurrected Schizopelte.
Everniopsis is a fungal genus in the family Parmeliaceae. It consists of a single species, the bark-dwelling lichen Everniopsis trulla, which occurs in Africa and South America.
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.
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.
Allantoparmelia is a genus of lichenised fungi in the large family Parmeliaceae. It is a genus of only three currently accepted species. All three Allantoparmelia lichens have a foliose growth form. They appear to be a very slow growing group of lichens, with a mean annual thallus diameter increase of only 0.23–0.35 mm per year.
Cornicularia is a genus of lichenised ascomycetes in the large family Parmeliaceae. It is a monotypic genus, with a single currently accepted species, the saxicolous lichen Cornicularia normoerica. This species has an erect caespitose growth form, and is sometimes referred to as the brittle lichen.
Oropogon is a genus of lichenised ascomycetes in the large family Parmeliaceae. It is a genus of roughly 40 currently accepted species. It was previously included in the family Alectoriaceae, but this group has since been subsumed into the Parmeliaceae.
Trapeliaceae is a family of lichens in the order Baeomycetales. The family contains 12 genera and about 125 species.
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.
Roccellographaceae is a family of lichen-forming fungi in the order Arthoniales. It contains three genera: Dimidiographa, Fulvophyton, and Roccellographa.
Lichenostigmatales is an order of fungi in the class Arthoniomycetes. It contains the single family Phaeococcomycetaceae. Lichenostigmatales was circumscribed in 2013 by Damien Ertz, Paul Diederich, and James D. Lawrey, with genus Lichenostigma assigned as the type. Using molecular phylogenetics, they identified a lineage of taxa in the Arthoniomycetes that were phylogenetically distinct from the order Arthoniales. Species in the Lichenostigmatales include black yeasts, lichenicolous, and melanised rock-inhabiting species.
