The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Many members of the Teloschistaceae are readily identifiable by their vibrant orange to yellow hue, a result of its frequent anthraquinone content. The presence of these anthraquinone pigments, which confer protection from ultraviolet light, enabled this group to expand from shaded forest habitats to harsher environmental conditions of sunny and arid ecosystems during the Late Cretaceous. Collectively, the family has a cosmopolitan distribution, although members occur predominantly in subtropical and temperate regions. Although most members either live on rock or on bark, about 40 species are lichenicolous–meaning they live on other lichens.
Gyalolechia is a genus of lichen-forming fungi belonging to the family Teloschistaceae. It contains 18 species of crustose lichens.
Austroplaca is a genus of lichen-forming fungi in the family Teloschistaceae. It has 10 species. The genus was circumscribed in 2013 by Ulrik Søchting, Patrik Frödén, and Ulf Arup, with Austroplaca ambitiosa assigned as the type species.
Calogaya is a genus of lichen-forming fungi belonging to the family Teloschistaceae. It has 19 species. The genus was circumscribed in 2013 by Ulf Arup, Ulrik Søchting, and Patrik Frödén. The generic name Calogaya honours Dr. Ester Gaya, a Spanish botanist from the University of Barcelona.
Flavoplaca is a genus of crust-like or scaly lichens in the family Teloschistaceae. It has 28 species with a mostly Northern Hemisphere distribution.
Xanthocarpia is a genus of mostly crustose lichens in the family Teloschistaceae. It has 12 species with a largely Northern Hemisphere distribution.
Rufoplaca is a genus of lichen-forming fungi in the family Teloschistaceae. The genus was circumscribed in 2013 by Ulf Arup, Ulrik Søchting, and Patrik Frödén, with Rufoplaca subpallida assigned as the type species.
Parvoplaca is a genus of lichen-forming fungi in the family Teloschistaceae. The genus was circumscribed in 2013 by Ulrik Søchting, Patrik Frödén, and Ulf Arup.
Squamulea is a genus of lichen-forming fungi in the family Teloschistaceae. It has 15 species. The genus was circumscribed in 2013 by Ulf Arup, Ulrik Søchting, and Patrik Frödén, with Squamulea subsoluta assigned as the type species. Five species were included in the original account of the genus. The genus name alludes to the squamulose growth form of most of its species. Squamulea has a worldwide distribution; when the genus was originally created, the centre of distribution was thought to be in southwestern North America.
Dufourea is a genus of mostly foliose lichen species in the subfamily Xanthorioideae of the family Teloschistaceae. Species in the genus are mostly found in the Southern Hemisphere.
Calogaya arnoldii is a species of saxicolous (rock-dwelling), crustose lichen that is common and widespread in Europe and Asia. It is in the family Teloschistaceae. It was first formally described as a new species in 1876 by Hugh Algernon Weddell, as a species of Lecanora. After being transferred to Caloplaca in 1915, it was considered as a member of that genus for nearly a century. Molecular phylogenetic studies showed Caloplaca to be polyphyletic, and it was divided up into several smaller genera in 2013. Calogaya arnoldii was one of eight species transferred to the newly circumscribed Calogaya by Ulf Arup, Patrik Frödén, and Ulrik Søchting. The lichen is part of a species complex with complicated taxonomy, and in which intermediate phenotypes are frequently observed, making it difficult to reliably distinguish them. Calogaya saxicola is one such similar species, and it has often been confused with C, arnoldii in areas where they co-occur, as the differences between them are subtle.
Wetmoreana is a genus of lichen-forming fungi in the family Teloschistaceae. It has two crustose, saxicolous (rock-dwelling) species.
Stellarangia is a genus of lichen-forming fungi in the family Teloschistaceae. It has three species of saxicolous (rock-dwelling), crustose lichens. Species of Stellarangia are found in dry, desert areas in Namibia and South Africa.
Xanthocarpia crenulatella is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae.
Austroplaca hookeri is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It was originally described by Carroll William Dodge in 1965, as Gasparrinia hookeri. The type specimen was originally collected by British botanist and explorer Joseph Dalton Hooker on Cockburn Island; the species is named in his honour. The taxon was transferred to the large genus Caloplaca in 2004, and again to the genus Austroplaca in 2013 as part of a restructuring of the family Teloschistaceae.
Gondwania is a genus of lichen-forming fungi in the subfamily Xanthorioideae of the family Teloschistaceae. It has three species. The genus was circumscribed by lichenologists Ulrik Søchting, Patrik Frödén, and Ulf Arup. The type species is G. cribrosa, a species that was first named Polycauliona cribrosa by Auguste-Marie Hue in 1909. The genus name refers to the ancestral supercontinent Gondwana.
Stellarangia namibensis is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It was first formally described in 1988 by Ingvar Kärnefelt, as a member of the genus Caloplaca. The type specimen was collected by the author from the gravel flats east of Cape Cross, in Omaruru, Namibia. The same species was collected from Angola by Austrian botanist Friedrich Welwitsch in 1859. The taxon was transferred to the genus Stellarangia in 2013 by Ulrik Søchting and colleagues, as part of a molecular phylogenetics-based restructuring of the Teloschistaceae.
Polycauliona polycarpa is a species of corticolous (bark-dwelling), fruticose lichen in the family Teloschistaceae. It was first formally described by German botanist Georg Franz Hoffmann in 1796, as Lobaria polycarpa. It has acquired quite an extensive synonymy in its taxonomic history. In 2013, Patrik Frödén and colleagues transferred it to the genus Polycauliona, as part of a molecular phylogenetics-based restructuring of the family Teloschistaceae. In northern North America, one vernacular name for the species is pin-cushion sunburst lichen.
Sirenophila gintarasii is a species of lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk and Ingvar Kärnefelt, as a member of the genus Caloplaca. The type specimen was collected by the authors from the Camel Rock reserve. There it was found growing on coastal rock outcrops, along with the crustose species Sirenophila eos and Dufourea ligulata, some of which had been deformed by the lichenicolous fungus species Arthonia sytnikii and Pyrenidium actinellum. The species epithet honours Tasmanian lichen lichenologist Gintaras Kantvilas. Ulf Arup and colleagues transferred the taxon to the genus Sirenophila in 2013, following a molecular phylogenetics-based restructuring of the family Teloschistaceae. Sirenophila gintarasii occurs in New South Wales and Victoria.
Sirenophila eos is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It was first formally described as a new species in 2007 by Sergey Kondratyuk and Ingvar Kärnefelt, as Caloplaca eos. The type specimen was collected from rhyolite outcrops in New South Wales. Ulf Arup and colleagues transferred the taxon to the newly circumscribed genus Sirenophila in 2013, following a molecular phylogenetics-based restructuring of the Teloschistaceae.
