The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
The Letrouitiaceae are a family of lichen-forming fungi belonging to the order Teloschistales. The family, which has a tropical and subtropical distribution, contains the single genus Letrouitia, which contains about 15 species. The family and the genus, both circumscribed in 1982 by André Bellemère and Josef Hafellner, are named in honour of Marie-Agnès Letrouit-Galinou.
Toninia is a genus of lichen-forming fungi in the family Ramalinaceae.
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.
Carbonea is a genus of fungi in the family Lecanoraceae. Most of the species grow on lichens. The genus is widespread, and contains 20 species. Carbonea was originally circumscribed as a subgenus of Lecidea in 1967 before it was promoted to generic status in 1983.
Lecidella is a genus of crustose lichens in the family Lecanoraceae.
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.
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.
Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was circumscribed in 1994 by Gintaras Kantvilas and John Alan Elix. It was emended in 2008 by the inclusion of Pyrrhospora species containing the anthraquinone russulone in their apothecia and having a prosoplectenchymatous exciple. The family Ramboldiaceae was circumscribed in 2014 to contain the genus.
The Lecideaceae are a family of lichens in the order Lecideales.
Fuscidea is a genus of crustose lichens in the family Fuscideaceae. It has about 40 species. The genus was circumscribed in 1972 by lichenologists Volkmar Wirth and Antonín Vězda, with Fuscidea aggregatilis assigned as the type species.
Protoparmelia is a genus of lichenized fungi in the family Parmeliaceae. The genus has a widespread distribution, and contains 11 species. Protoparmelia was circumscribed by French lichenologist Maurice Choisy in 1929.
Myriolecis is a genus of lichen in the family Lecanoraceae. It was originally circumscribed in 1909 by Frederic E. Clements with Myriolecis sambuci as the type species. The genus was later reinstated to accommodate the Lecanora disperse group and Arctopeltis. Molecular phylogenetic data showed that this group of species formed a clade that is genetically distinct from Lecanora, and Myriolecis was the oldest name available to hold these species.
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".
Trapeliaceae is a family of lichens in the order Baeomycetales. The family contains 12 genera and about 125 species.
Bilimbia is a genus of lichen-forming fungi in the family Ramalinaceae.
Schaereria is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes.
Bryostigma is a genus of lichen-forming fungi of uncertain familial placement in the order Arthoniales. The genus was circumscribed in 1979 by Josef Poelt and Peter Döbbeler, with the muscicolous lichen Bryostigma leucodontis assigned as the type species. A dozen Arthonia species were transferred into the genus in 2020 following molecular phylogenetic analysis of the family Arthoniaceae that showed distinct phylogenetic lineages that were basal to that family. The genus contains several parasitic species that occur on hosts having chlorococcoid photobionts.
