Dactylina is a genus of lichen-forming fungi in the family Parmeliaceae. [2] The genus was circumscribed by Finnish botanist William Nylander in 1860, with Dactylina arctica assigned as the type species. [3]
Rimularia is a genus of lichenized fungi in the family Trapeliaceae. Rimularia was circumscribed by Finnish botanist William Nylander in 1868.
Ptychographa is a genus of lichenized fungi in the family Xylographaceae. It is a monotypic genus, containing the single species Ptychographa xylographoides. Both the species and genus were described as new in 1874 by Finnish botanist William Nylander.
Lithographa is a genus of lichenized fungi in the family Xylographaceae. The genus was circumscribed in 1857 by Finnish botanist William Nylander, with Lithographa petraea assigned as the type species. This species is now known as Lithographa tesserata.
Pilophorus is a genus of lichenized fungi in the family Cladoniaceae. They are commonly known as matchstick lichens. The genus has a widespread distribution, especially in temperate regions, and contains 11 species.
Gymnoderma is a genus of lichen-forming fungi in the family Cladoniaceae. It has three species. The genus was circumscribed by Finnish botanist William Nylander in 1860. Nylander assigned Gymnoderma coccocarpum as the type species in 1869; this species was originally collected from the Himalayas. It occurs throughout southeastern Asia.
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.
Flavopunctelia is a genus of foliose lichens in the family Parmeliaceae. The genus contains species that are widespread in temperate and tropical areas. The genus is characterised by broad, yellow-green lobes, point-like (punctiform) pseudocyphellae on the thallus surface, and bifusiform conidia. All species contain usnic acid as a major secondary chemical in the cortex. Flavopunctelia was originally conceived as a subgenus of Punctelia by Hildur Krog in 1982; Mason Hale promoted it to generic status in 1984.
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.
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.
Pyrrhospora is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855, with Pyrrhospora quernea assigned as the type species.
Euopsis is a genus of lichen-forming fungi in the family Harpidiaceae. The genus contains two species. 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.
Placynthium is a genus of lichen-forming fungi in the family Placynthiaceae. Members of this genus are commonly called blackthread lichens.
Melaspilea is a genus of lichen-forming and lichenicolous fungi in the family Melaspileaceae. The genus was circumscribed by Finnish lichenologist William Nylander in 1857.
Xylographaceae is a family of lichen-forming fungi in the order Baeomycetales. It contains four genera and 25 species.
Pyrenidium is a genus of lichenicolous (lichen-dwelling) fungi. It is the only genus in the family Pyrenidiaceae. It has 13 species.
