The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Trapeliopsis is a genus of lichenized fungi in the family Trapeliaceae. It contains 20 species. The genus was circumscribed in 1980 by Hannes Hertel and Gotthard Schneider, with Trapeliopsis wallrothii designated as the type species.
Anzina is a genus of lichenized fungi of uncertain familial and ordinal classification in the subclass Ostropomycetidae. It is a monotypic genus, containing the single species Anzina carneonivea. This lichen was first described by Italian botanist Martino Anzi in 1868, as Gyalolechia carneonivea. German lichenologist Christoph Scheidegger circumscribed the genus Anzina in 1982.
Heteromyces is a genus of lichenized fungi in the family Cladoniaceae. It is a monotypic genus, containing the single species Heteromyces rubescens. Both the genus and species were described by Swiss lichenologist Johannes Müller Argoviensis in 1889. The name Heteromyces was also used for a genus circumscribed by Lindsay S. Olive in 1957; this usage is illegitimate because of the prior usage of this name by Müller. Olive's concept of Heteromyces was renamed to Oliveonia by Marinus Anton Donk in 1958.
Frutidella is a genus of lichen-forming fungi in the family Ramalinaceae. It contains three species. The genus was circumscribed in 1994 by Klaus Kalb to contain the species formerly known as Lecidea caesioatra.
Acanthotrema is a genus of lichens in the family Graphidaceae. The genus was circumscribed by German lichenologist Andreas Frisch in 2006, with Acanthotrema brasilianum assigned as the type species.
Ingaderia is a genus of lichen-forming fungi in the family Opegraphaceae. The genus was circumscribed by British botanist Otto Vernon Darbishire in 1897.
Norrlinia is a genus of two species of fungi in the family Verrucariaceae. The genus was circumscribed by Ferdinand Theissen and Hans Sydow in 1918. The genus name honours the Finnish botanist Johan Petter Norrlin.
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.
Sagiolechia is a genus of lichen-forming fungi in the family Sagiolechiaceae.
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.
Spilonema is a genus of lichen-forming fungi in the family Coccocarpiaceae.
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.
Xenonectriella is a genus of lichenicolous fungi in the family Nectriaceae. The genus was circumscribed by lichenologist Josef Karl Weese in 1919, with Xenonectriella lutescens assigned as the type species.
Vezdaea is a genus of crustose lichens in the monotypic family Vezdaeaceae, which itself is the only taxon in the order Vezdaeales. The genus was circumscribed by Tscherm.-Woess & Josef Poelt in 1976. The genus name honours Czech lichenologist Antonín Vězda.
Hydropunctaria is a genus of crustose lichens in the family Verrucariaceae. It has 8 species. The genus was circumscribed in 2009 by Christine Keller, Cécile Gueidan, and Holger Thüs, with Hydropunctaria maura assigned as the type species.
Xylographaceae is a family of lichen-forming fungi in the order Baeomycetales. It contains four genera and 25 species.
Lambiella is a genus of lichen-forming fungi in the family Xylographaceae. The genus was circumscribed by German botanist Hannes Hertel in 1984, with Lambiella psephota assigned as the type species.
Toensbergia is a genus of lichen-forming fungi in the family Sporastatiaceae. The genus was circumscribed by Mika Bendiksby and Ernst 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.
Steineropsis is a genus of lichen-forming fungi in the family Pannariaceae. It has two species. The genus was circumscribed by Toby Spribille and Lucia Muggia in 2010, with Steineropsis alaskana assigned as the type species. The type specimen of this lichen was found in Skagway, Alaska, where it was growing on a rock in a snowbed at an altitude of 1,051 m (3,448 ft). The generic name alludes to a resemblance to the genus Steinera. A second species, Steineropsis laceratula, also found in Alaska, was added to the genus in 2020.
