Psora is a genus of lichen-forming fungi in the family Psoraceae. Members of the genus are commonly called fishscale lichens. Lichens in the genus Psora are known to have a squamulose thallus and anthraquinones in the hymenium.
Myelorrhiza is a genus of two Australian species of lichenized fungi in the family Ramalinaceae. It was circumscribed in 1986 by Australian lichenologists Doug Verdon and John A. Elix. Myelorrhiza was originally classified in the family Cladoniaceae until Kistenich and colleagues, using molecular phylogenetic analysis, showed that it is more appropriately placed with the Ramalinaceae.
Crustospathula is a genus of five species of crustose lichens in the family Malmideaceae. They are characterized by their stalked and sometimes branched cartilaginous soredia and Bacidia-like apothecia.
Phyllopsora is a genus of lichenized fungi in the family Ramalinaceae. It was circumscribed by Swiss botanist Johannes Müller Argoviensis in 1894.
Toniniopsis is a genus of crustose and squamulose lichens in the family Ramalinaceae. The genus was circumscribed by Swiss lichenologist Eduard Frey in 1926, with Toniniopsis obscura designated the type and only species. The genus name of Toniniopsis is in honour of Carlo Tonini (1803–1877), who was an Italian chemist and botanist (Lichenology), who worked in Verona and was a member and President of the Academy of Agriculture. As a result of molecular phylogenetic studies, several species, formerly classified in genus Bacidia, have been transferred to Toniniopsis.
Toninia is a genus of lichen-forming fungi in the family Ramalinaceae.
Pycnora is a genus of fungi in the monotypic family Pycnoraceae. It contains three species. The genus was circumscribed by Josef Hafellner in 2001; the family was proposed by Mika Bendiksby and Einar Timdal in 2013.
Rhizocarpaceae is a family of crustose, lecideoid, lichen-forming fungi and together with the family Sporastatiaceae it constitutes the order Rhizocarpales in the Ascomycota, class Lecanoromycetes.
Hypocenomyce is a genus of lichen-forming fungi in the family Ophioparmaceae. Species in the genus grow on bark and on wood, especially on burned tree stumps and trunks in coniferous forest. Hypocenomyce lichens are widely distributed in the northern hemisphere.
The Tephromelataceae are a family of lichenized fungi in the order Lecanorales. The family was circumscribed by Austrian lichenologist Josef Hafellner in 1984. Tephromelataceae comprises the genera Tephromela, Calvitimela, Mycoblastus and Violella, which together constitute a well-supported monophyletic group.
Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales. It contains eight genera and about 70 species.
Solenopsora is a genus of lichen-forming fungi in the family Catillariaceae. It has 15 species, with a mostly Northern Hemisphere distribution.
Bibbya is a genus of fruticose lichens in the family Ramalinaceae.
Toensbergia is a genus of lichen-forming fungi in the family Sporastatiaceae. The genus was circumscribed by Mika Bendiksby and Einar Timdal in 2013. The genus name honours Norwegian lichenologist Tor Tønsberg, "in appreciation of his important work on sorediate, corticolous lichens". The type species is Toensbergia leucococca, which was formerly classified in genus Hypocenomyce, presumably due to its resemblance to Hypocenomyce xanthococca.
Rhizocarpales are an order of lichen-forming fungi in the subclass Lecanoromycetidae of the class Lecanoromycetes. It has two families, Rhizocarpaceae and Sporastatiaceae, which contain mostly crustose lichens.
Sporastatia is a genus of crustose lichens in the family Sporastatiaceae. It has four species. Sporastatia lichens are long-lived species that grow on siliceous or weakly calcareous rocks in arctic and alpine locales.
Carbonicola is a small genus of lichen-forming fungi. It is the sole genus in the monogeneric family Carbonicolaceae. The genus, which collectively has an almost cosmopolitan distribution, contains three squamulose lichens that prefer to grow on burned wood in temperate areas of the world.
Psora taurensis is a species of terricolous (ground-dwelling), squamulose lichen in the family Lecanoraceae. It is found in the Taurus Mountains of Turkey.
Biatora oxneri is a species of corticolous (bark-dwelling) lichen in the family Ramalinaceae. It is found in the Russian Far East and in South Korea.
Phyllopsora amazonica is a species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae. It is found in the Amazon rainforest of Brazil.
