The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909.
Fuscopannaria is a genus of lichen-forming fungi in the family Pannariaceae. It has 55 species.
Byssoloma is a genus of leaf-dwelling lichens in the family Pilocarpaceae.
Septotrapelia is a genus of lichen-forming fungi in the family Pilocarpaceae. It has four species. It was validly published as a genus in 2007 by lichenologists André Aptroot and Jose-Luis Chaves.
Lopadium is a genus of lichen-forming fungi in the monotypic family Lopadiaceae, which is in the order Lecideales. The genus contains 10 species. Lopadium was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855.
Bulbothrix is a genus of lichen-forming fungi in the family Parmeliaceae. This genus is synonymous with Bulbothricella V.Marcano, S.Mohali & A.Morales. Bulbothrix was circumscribed by lichenologist Mason E. Hale in 1974 with Bulbothrix semilunata as the type species.
Peltula is a genus of small dark brown to olive or dark gray squamulose lichens that can be saxicolous ) or terricolous. Members of the genus are commonly called rock-olive lichens. They are cyanolichens, with the cyanobacterium photobiont from the genus Anacystis. They are umbilicate with flat to erect squamule lobes that attach from a central holdfast or cluster of rhizenes. Lichen spot tests are usually negative.
Absconditella is a genus of lichenised fungi in the family Stictidaceae. The genus was circumscribed in 1965 by Czech lichenologist Antonín Vězda, with Absconditella sphagnorum assigned as the type species. Absconditella is characterised by gyalectoid apothecia with a hymenium that is not amyloid, without a dark pigment and thalli containing green algae as photobionts. The genus name means "hidden", a reference to the scant structure of the thallus and its small apothecia.
Dibaeis is a genus of lichen-forming fungi in the family Icmadophilaceae. The genus is widely distributed in tropical regions. Dibaeis was circumscribed in 1909 by Frederic Edward Clements with Dibaeis rosea as the type species. Several species were transferred from other genera in a 1993 publication.
Baeomyces is a genus of lichenized fungi in the family Baeomycetaceae. Members of Baeomyces are commonly called cap lichens. The genus was circumscribed by German mycologist Christiaan Hendrik Persoon in 1794. Although Persoon did not designate a type species in his original description of the genus, Frederick Clements and Cornelius Lott Shear assigned Baeomyces byssoides as the type in 1931.
Dibaeis baeomyces, commonly known as pink earth lichen, is a fruticose lichen belonging to the family Icmadophilaceae.
Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales. It contains eight genera and about 70 species.
Coenogonium is a genus of crustose lichens in the monotypic family Coenogoniaceae. It has about 90 species. Most species are leaf-dwelling or grow on bark, although a few are known to grow on rocks under certain conditions, and some are restricted to growth on termite nests. The genus was circumscribed in 1820 by German naturalist Christian Gottfried Ehrenberg.
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.
Megalospora is a genus of lichen-forming fungi in the family Megalosporaceae.
Spirographa ciliata is a species of lichenicolous fungus in the family Spirographaceae. It was first formally described by Klaus Kalb in 1993 as Cornutispora ciliata. Adam Grzegorz Flakus, Javier Etayo, and Jolanta Miądlikowska transferred it to genus Spirographa in 2019.
Nigrovothelium is a genus of lichen-forming fungi in the family Trypetheliaceae. It has three species. The genus was circumscribed in 2016 by lichenologists Robert Lücking, Matthew Nelsen, and André Aptroot, to contain species formerly in the Trypethelium tropicum species group. The type species, Nigrovothelium tropicum, was originally described by Erik Acharius in 1810, as a species of Verrucaria.
Fulvophyton is a genus of lichen-forming fungi in the family Roccellographaceae. It has 11 species. Fulvophyton is characterised by its crust-like thallus, which is often pale yellowish-brown in colour. This genus features a photobiont from the green algal genus Trentepohlia and exhibits a unique arrangement of reproductive structures.
