Euopsis is a genus of lichen-forming fungi in the family Harpidiaceae. The genus contains two species. [1] The genus was circumscribed by Finnish botanist William Nylander in 1881. [2]
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci of the Lecanoromycetes most often release spores by rostrate dehiscence.
Capnodiales is a diverse order of Dothideomycetes, initially based on the family Capnodiaceae, also known as sooty mold fungi. Sooty molds grow as epiphytes, forming masses of black cells on plant leaves and are often associated with the honeydew secreted by insects feeding on plant sap. This diverse order has been expanded by the addition of several families formerly thought unrelated and now also includes saprobes, endophytes, plant pathogens, lichens and rock-inhabiting fungi. The new additions include the genus Mycosphaerella containing the causal agents of several economically important crop and tree diseases. A small number of these fungi are also able to parasitise humans and animals, including species able to colonise human hair shafts.
The Lichinaceae are a family of ascomycete fungi. Most species are lichenized with cyanobacteria, and have a distribution largely in temperate regions.
Staurothele is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. It has about 40 species. When the fungus is part of a lichen, the genus of lichen is commonly called rock pimples.
Endococcus is a genus of lichenicolous (lichen-dwelling) in the family Lichenotheliaceae. It has 44 species. The genus was circumscribed by the Finnish botanist William Nylander in 1855. Although at least one source places the genus in the Verrucariaceae, a 2016 study of the type species, Endococcus rugulosus, determined that it should instead be placed in the family Lichenotheliaceae of the order Dothideales; this classification echoes a placement proposed in 1979 by David Hawksworth.
Sarcopyrenia is a genus of lichenicolous (lichen-dwelling) fungi. It has 11 species. It is the only genus in Sarcopyreniaceae, a family in the order Verrucariales. Sarcopyrenia was circumscribed by Finnish lichenologist William Nylander in 1858, with Sarcopyrenia gibba assigned as the type species. Sarcopyreniaceae is one of the few families composed entirely of lichenicolous fungi.
Xanthopyreniaceae is a family of lichen-forming fungi in the order Collemopsidiales. The family was circumscribed by lichenologist Alexander Zahlbruckner in 1926.
Tylophoron is a genus of lichen-forming fungi in the family Arthoniaceae. The genus was circumscribed in 1862 by Finnish lichenologist William Nylander.
Frigidopyrenia is a fungal genus in the family Xanthopyreniaceae. It is a monotypic genus, containing the single species Frigidopyrenia bryospila, a subarctic crustose lichen. This lichen was originally described by Finnish lichenologist William Nylander in 1864 as Verrucaria bryospila. It was shuffled to several genera in its taxonomic history before Martin Grube circumscribed Frigidopyrenia in 2005 to contain it. As of 2017, no molecular sequence data was available for Frigidopyrenia.
Collemopsidium is a genus of fungi in the family Xanthopyreniaceae. Some members of this genus are marine species, and described as "borderline lichens" or "algicolous" fungi. The genus was circumscribed by Finnish botanist William Nylander in 1881.
Thelopsis is a genus of lichenized fungi in the family Stictidaceae. It was circumscribed by Finnish lichenologist William Nylander in 1855, with Thelopsis rubella as the type species.
Leptochidium is a genus of lichen-forming fungi in the family Massalongiaceae. It has two species:
Dactylina is a genus of lichen-forming fungi in the family Parmeliaceae. The genus was circumscribed by Finnish botanist William Nylander in 1860, with Dactylina arctica assigned as the type species.
Varicellaria is a genus of crustose lichens. It is the only genus in the family Varicellariaceae.
Hyaloraphidium is a genus of chytrid-like fungi. It is the only member of the family Hyaloraphidiaceae, order Hyaloraphidiales and class Hyaloraphidiomycetes in the division Monoblepharomycota.
Harpidiaceae is a small family of lichen-forming fungi, containing two genera and five species. It is of uncertain classification in the Pezizomycotina.
Thelenella is a genus of lichen-forming fungi in the family Thelenellaceae. It has 30 species. The genus was circumscribed by Finnish lichenologist William Nylander in 1855, with Thelenella modesta assigned as the type species.
Thelenellaceae is a family of lichen-forming fungi. It is the sole family in the monotypic order Thelenellales, and contains three genera and about 50 species.
Pyrenidium is a genus of lichenicolous (lichen-dwelling) fungi. It is the only genus in the family Pyrenidiaceae. It has 13 species.
Cryptoschizotrema is a genus of lichen-forming fungi in the family Graphidaceae. It has two species. The genus was circumscribed in 2019 by lichenologists André Aptroot, Robert Lücking, and Marcela Cáceres. The genus name alludes to the similarity in anatomy with Schizotrema species. This resemblance is due to the partially carbonized, concentrically layered, and fissured excipulum, which gives the impression that the Schizotrema-like excipulum is concealed beneath a protective layer. The type species was originally described by William Nylander in 1867, as a species of Thelotrema.
