Biatorellaceae is a family of lichen-forming fungi in the subclass Lecanoromycetidae. The family is monotypic, and contains the single genus Biatorella, which contains eight species. Species in the genus are found in northern temperate regions, especially in Europe.
The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
The Acarosporaceae are a family of fungi in the order Acarosporales. Members of this family have a widespread distribution, and are mostly 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.
Krogia is a genus of corticolous lichens in the family Ramalinaceae. It occurs in tropical humid forests and rainforests. The genus was circumscribed by Norwegian lichenologist Einar Timdal in 2002, with Krogia coralloides assigned as the type species.
Xanthopyreniaceae is a family of lichen-forming fungi in the order Collemopsidiales. The family was circumscribed by lichenologist Alexander Zahlbruckner in 1926.
Bryonora is a genus of crustose lichens in the family Lecanoraceae. The genus was circumscribed in 1983 by lichenologist Josef Poelt, with Bryonora castanea assigned as the type species.
Bryodina is a genus of two species of crustose lichens in the family Lecanoraceae. It was circumscribed by Austrian lichenologist Josef Hafellner in 2001 as a segregate of the large genus Lecanora. It is distinguished from the morphologically similar genus Bryonora by the clearly separated hypothecium and excipulum, and by the thin-walled ascospores.
Calvitimela is a lichen genus in the family Tephromelataceae. Members of the family Tephromelataceae are crustose lichens with green photobionts and lecideine or lecanorine apothecia. The species in Calvitimela have lecideine apothecia, are saxicolous and are primarily found in alpine to arctic regions.
Miriquidica is a genus of lichen in the family Lecanoraceae. The genus was circumscribed in 19876 by lichenologists Hannes Hertel and Gerhard Rambold, with Miriquidica complanata assigned as the type species. According to Dictionary of the Fungi, the widespread genus contains 23 species, found predominantly in arctic-alpine regions.
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.
Protomicarea is a genus of lichen-forming fungi in the family Psoraceae. The genus contains two species: Protomicarea limosa and Protomicarea alpestris. Protomicarea was circumscribed by lichenologist Josef Hafellner in 2001.
The Lecideaceae are a family of lichens in the order Lecideales.
The Ophioparmaceae are a small family of lichen-forming fungi in the order Umbilicariales. The family was circumscribed in 1988 by lichenologists Roderick Westgarth Rogers and H. Thorsten Lumbsch.
Rhizocarpon is a genus of crustose, saxicolous, lecideoid lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus forming border-like bands between colonies in some species, like the common map lichen.
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.
Josef Hafellner is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus Karschia. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae has been described as "probably the single most influential publication in lichen systematics in the latter half of the 20th century".
Bilimbia is a genus of lichen-forming fungi in the family Ramalinaceae.
Eiglera is a genus of crustose lichens belonging to the family Eigleraceae. Eiglera species are found in Europe and Northern America.
Helmut Mayrhofer is an Austrian lichenologist. He is known for his expertise on the lichen family Physciaceae and his studies of the lichen flora of the Balkan Peninsula, the Alps, and other regions.
