Strigula is a genus of lichen-forming fungi in the family Strigulaceae. [1] The genus was circumscribed in 1823 by English mycologist Elias Magnus Fries.
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.
Lithothelium is a genus of lichen-forming fungi in the family Pyrenulaceae. Most of the species are found in tropical climates, and are usually corticolous (bark-dwelling) or saxicolous (rock-dwelling). The genus was circumscribed by Swiss botanist Johannes Müller Argoviensis in 1885.
Porina is a genus of lichens in the family Trichotheliaceae. A 2020 estimate places about 145 species in the widespread genus.
Fellhanera is a genus of mostly leaf-dwelling lichens in the family Pilocarpaceae. The genus, circumscribed by lichenologist Antonín Vězda in 1986, honours Austrian lichenologist Josef Hafellner.
Byssoloma is a genus of leaf-dwelling lichens in the family Pilocarpaceae.
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.
Enterographa is a genus of lichens in the family Roccellaceae.
Opegrapha is a genus of lichenized fungi in the family Opegraphaceae. Species include:
Stigmidium is a genus of lichenicolous (lichen-eating) fungi in the family Mycosphaerellaceae. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1860, with Stigmidium schaereri assigned as the type species.
Anisomeridium is a genus of lichens in the family Monoblastiaceae. The type species was originally named Arthopyrenia xylogena by Swiss botanist Johannes Müller Argoviensis in 1883; in 1928, Maurice Choisy defined the genus Anisomeridium, designating A. xylogena the type species.
Endocarpon is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. The genus was circumscribed by German bryologist Johann Hedwig in 1789.
Gyalideopsis is a genus of lichens in the family Gomphillaceae. The genus was circumscribed by Czech lichenologist Antonín Vězda in 1972.
Gyalecta is a genus of lichen-forming fungi in the family Gyalectaceae that contains 50 species. Gyalecta was circumscribed by lichenologist Erik Acharius in 1808. It forms associations with Trentepohlia algae.
Arthopyrenia is a genus of fungi in the family Trypetheliaceae. It was formerly classified in the eponymic family Arthopyreniaceae, but molecular phylogenetics studies showed that the type species, Arthopyrenia cerasi, was a member of the Trypetheliaceae.
Strigulaceae is a family of lichen-forming fungi, one of two families in the order Strigulales. Recent (2020) molecular analysis of the type genus, Strigula, has led to a reallocation of the foliicolous species into six genera that correspond to well-delimited clades with diagnostic phenotype features.
Thelenella is a genus of lichen-forming fungi in the family Thelenellaceae. It has 30 species. The genus was circumscribed by Finnish lichenologist William Nylander in 1855, with Thelenella modesta assigned as the type species.
Swinscowia is a genus of lichen-forming fungi in the family Strigulaceae. It has 34 species. Swinscowia was proposed in 2020 by lichenologists Shu-Hua Jiang, Robert Lücking, and Emmanuël Sérusiaux to contain non-foliicolous species that were isolated from bark and rocks. Swinscowia jamesii, a species that was originally described in genus Geisleria, and later transferred to Strigula, is the type species of the genus. The genus name honours British lichenologist Dougal Swinscow, who originally described the type species in 1967.
