The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Rimularia is a genus of lichenized fungi in the family Trapeliaceae. Rimularia was circumscribed by Finnish botanist William Nylander in 1868.
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.
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.
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.
Sagiolechia is a genus of lichen-forming fungi in the family Sagiolechiaceae. The genus was circumscribed by lichenologist Abramo Bartolommeo Massalongo in 1854, who assigned Sagiolechia protuberans as the type species. The family Sagiolechiaceae was proposed in 2010 to contain Sagiolechia as the type genus, and genus Rhexophiale; molecular phylogenetic analysis showed that these two genera formed a distinct clade in the Ostropales.
The Lecideaceae are a family of lichen-forming fungi in the order Lecideales. It contains about 30 genera and roughly 250 species. A major distinguishing characteristic of the family is the lecanoroid form of the fruiting bodies: typically circular, dark, and without a thalline margin. Most species in the family are lichenised with green algae, although a few species, scattered amongst several genera, are lichenicolous—they live on other lichens. Lecideaceae lichens tend to grow on rocks, wood, and soil. Several Lecideaceae species accelerate the weathering of rock surfaces, a process known as pedogenesis, by extending their hyphae into cracks and expelling rock flakes. This contributes to significantly faster weathering rates in certain environments, impacts various materials from natural rocks to man-made Sekishu roof tiles, and involves key biomolecules identified for survival and biodeterioration, including compounds to withstand intense ultraviolet radiation.
Poeltiaria is a genus of lichen-forming fungi in the family Lecideaceae. It was circumscribed in 1984 by lichenologist Hannes Hertel, with Poeltiaria turgescens assigned as the type species.
Porpidia is a genus of crustose lichens in the family Lecideaceae.
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.
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.
Tephromela is a genus of lichens in the family Tephromelataceae. There are about 25 species in this widespread genus.
Trapeliaceae is a family of lichens in the order Baeomycetales. The family contains 12 genera and about 125 species.
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. Most Schaereria species are crustose lichens that live on rocks. Schaereria was first proposed by Gustav Wilhelm Körber in 1855 and was later taken up by other lichenologists despite periods of disuse.
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.
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 Einar 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.
