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".
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.
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.
Holmiella is a genus of fungi in the order Patellariales.
Peridiothelia is a genus of fungi in the family Pleomassariaceae. Peridiothelia oleae is a little-known species found in Europe.
Rechingeriella is a genus of fungi in the family Zopfiaceae; according to the 2007 Outline of Ascomycota, the placement in this family is uncertain.
Zopfia is a genus of fungi in the family Zopfiaceae. The widespread genus contained 5 species, until another species was accepted.
Muellerella is a genus of lichenicolous lichens in the family Verrucariaceae. The genus has a widespread distribution, especially in northern temperate areas, and contains species that live on other lichens, or on liverworts.
Melanohalea is a genus of foliose lichens in the family Parmeliaceae. It contains 30 mostly Northern Hemisphere species that grow on bark or on wood. The genus is characterized by the presence of pseudocyphellae, usually on warts or on the tips of isidia, a non-pored epicortex and a medulla containing depsidones or lacking secondary compounds. Melanohalea was circumscribed in 2004 as a segregate of the morphologically similar genus Melanelia.
Arthopyrenia is a genus of fungi within the Arthopyreniaceae family. The genus has a widespread distribution, a cosmopolitan distribution. It formerly contained about 117 species.
Sphaerodes is a genus of fungi within the Coronophorales order but it has not been placed within a family.
Bryoria is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens. The genus has a widespread distribution, especially in boreal and cool temperate areas.
Taeniolella is a genus of asexual fungi hyphomycetes in the family Mytilinidiaceae. Some of the species are lichenicolous (lichen-dwelling), others are saprophytic, while others are endophytic. The genus was circumscribed in 1958 by Canadian mycologist Stanley John Hughes, with Taeniolella exilis as the type species. Major revisions of the lichenicolous species in the genus were published in 2016 and 2018.
Lichenoconium is a genus of fungi belonging to the family Lichenoconiaceae.
Bachmanniomyces is a genus of fungi with unclear classification.
Cheiromycina is a genus of fungi belonging to the family Malmideaceae.
Lemonniera is a genus of fungi belonging to the family Discinellaceae.
