Ochrolechia is a genus of crustose lichens in the family Ochrolechiaceae. [3]
As of April 2021 [update] , Species Fungorum accepts 38 species of Ochrolechia: [4]
Biatora is a genus of lichens in the family Ramalinaceae. First described in 1817, the genus consists of crustose and squamulose lichens with green algal photobionts, biatorine apothecia, colorless, simple to 3-septate ascospores, and bacilliform pycnospores. According to the Dictionary of the Fungi, the genus contains 42 species that are widely distributed in temperate areas.
Bacidia is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was circumscribed by Giuseppe De Notaris in 1846. Species in the genus are crust-like lichens with stemless apothecia; they have green algae as photobionts. Their asci have 8 colourless, cylindrical to acicular, multiseptate spores, with curved and thread-like conidia.
Trapelia is a genus of lichenized fungi in the family Trapeliaceae.
Micarea is a genus of lichenized fungi in the family Pilocarpaceae. The widely distributed genus contains 126 species and new species are described actively. Species in the genus are crustose lichens and their photobiont is a single-celled green alga.
Opegrapha is a genus of lichenized fungi in the family Opegraphaceae. Species include:
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.
Lepraria is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains. Members of the genus are commonly called dust lichens. The main vegetative body (thallus) is made of patches of soredia. There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products are important characters to distinguish between similar species in Lepraria.
Coccotrema is a genus of lichen-forming fungi. It is the type genus of the family Coccotremataceae, in the order Pertusariales. The genus contains 16 species.
Mycoblastus is a genus of crustose lichens in the family Tephromelataceae. Members of the genus are commonly called blood lichens.
Catillaria is a genus of crustose lichens in the family Catillariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852. It is the type genus of Catillariaceae, which was circumscribed by Austrian lichenologist Josef Hafellner in 1984.
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.
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.
Lepra is a genus of lichen-forming fungi in the family Pertusariaceae. Although the genus was created in 1777, it was not regularly used until it was resurrected in 2016 following molecular phylogenetic analyses. It has more than 80 species, most of which were previously classified in genus Pertusaria.
Schizotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2009 by Armin Mangold and H. Thorsten Lumbsch.
Ochrolechia minuta is a species of crustose lichen in the family Ochrolechiaceae. It was first formally described in 1938 by Swedish lichenologist Gunnar Degelius as Perforaria minuta. The type specimen was collected from the Kodiak Island Borough in Alaska. Toby Spribille transferred it to the genus Ochrolechia in 2020, suggesting that the absence of cephalodia, and the presence of alectoronic acid, indicate that it is "related to the alectoronic acid-containing species of poriform Ochrolechia".
