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.
Trapelia is a genus of lichenized fungi in the family Trapeliaceae.
Herteliana is a genus of lichen-forming fungi. It contains four species of crustose lichens.
Schadonia is a genus of lichen-forming fungi. Established by German lichenologist Gustav Wilhelm Körber in 1859, this genus of crustose lichens is characterised by its black, sessile apothecia, muriform ascospores, and growth on mosses, plant debris, and rocks in montane habitats. While traditionally placed in the family Ramalinaceae, recent studies have suggested its classification may be uncertain within the order Lecanorales, with some researchers proposing its placement in the Pilocarpaceae or the resurrection of the family Schadoniaceae. The genus currently comprises four recognised species.
Lecania is a genus of lichenized fungi in the family Ramalinaceae. The genus was circumscribed by Abramo Bartolommeo Massalongo in 1853. Lecania is widely distributed, especially in temperate regions, and contains about 64 species.
Psilolechia is a genus of four species of crustose lichens. It is the only member of Psilolechiaceae, a family that was created in 2014 to contain this genus.
Skyttea is a genus of lichenicolous (lichen-dwelling) fungi in the family Cordieritidaceae. The genus was circumscribed in 1981 by lichenologists Martha Allen Sherwood, David L. Hawksworth, and Brian J. Coppins, with Skyttea nitschkei assigned as the type species.
Gyalectidium is a genus of lichen-forming fungi in the family Gomphillaceae. A 2020 estimates placed 52 species in the genus. The genus was circumscribed by Swiss lichenologist Johannes Müller Argoviensis in 1881. He included 3 species: G. xantholeucum, G. dispersum, and G. filicinum; the last of these is now the type species of the genus.
Ramonia is a genus of lichenized fungi in the family Gyalectaceae. It contains 24 species. The genus was circumscribed by Ernst Stizenberger in 1862.
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.
Leprocaulon is a genus of lichen-forming fungi in the family Leprocaulaceae. Members of the genus Leprocaulon are commonly called mealy lichens.
Xyleborus is a genus of lichen-forming fungi in the family Stereocaulaceae. It has two species. The genus was circumscribed in 2009 by Richard C. Harris and Douglas Ladd with Xyleborus sporodochifer assigned as the type species. A second species, X. nigricans, was added to the genus in 2015.
Trapeliaceae is a family of lichens in the order Baeomycetales. The family contains 12 genera and about 125 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 Elisabeth Tschermak-Woess and Josef Poelt in 1976. The genus name honours Czech lichenologist Antonín Vězda (1920-2008).
Bilimbia is a genus of lichen-forming fungi in the family Ramalinaceae.
Loxospora is a genus of lichen-forming fungi in the family Sarrameanaceae. It has 13 species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852, with Loxospora elatina assigned as the type species. This crustose lichen was originally named Lecanora elatina by Erik Acharius in 1810.
Halecania is a genus of fungi in the family Leprocaulaceae. It has 22 species. The genus was circumscribed by Austrian lichenologist Michaela Mayrhofer in 1987, with Halecania alpivaga assigned as the type species. She created Halecania to contain species, formerly placed in Lecania, with the following characteristics: uniformly amyloid apical domes, paraphyses with dark brown apical caps, and halonate ascospores.
Strangospora is a genus of lichen-forming fungi. It is the only genus in the family Strangosporaceae, which itself is of uncertain taxonomic placement in the Ascomycota. It contains 10 species.
