The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family has a cosmopolitan distribution, although its members occur predominantly in temperate regions. Most members are lichens that either live on rock or on bark, but about 40 species are lichenicolous – meaning they are non-lichenised fungi that live on other lichens. Many members of the Teloschistaceae are readily identifiable by their vibrant orange to yellow hue, a result of their 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.
Gallowayella is a genus of lichen-forming fungi in the family Teloschistaceae. It has 15 species. The genus was circumscribed in 2012 by Sergey Kondratyuk, Natalya Fedorenko, Soili Stenroos, Ingvar Kärnefelt, Jack Elix, and Arne Thell, with Gallowayella coppinsii assigned as the type species. The generic name honours New Zealand lichenologist David John Galloway (1942–2014).
Ovealmbornia is a monotypic genus of mostly foliose lichen species in the subfamily Xanthorioideae of the family Teloschistaceae. It now only contains one known species, Ovealmbornia reginae as others were classed as synonyms of other species in the same family.
Kaernefia is a genus of crustose lichens in the family Teloschistaceae. It has three species, found in Australia or South Africa.
Filsoniana is a genus of squamulose lichens in the family Teloschistaceae. It has six species. It was circumscribed in 2013 by Ingvar Kärnefelt, Arne Thell, Jae-Seoun Hur, Sergey Kondratyuk, and John Elix following a molecular phylogenetic analysis of the Teloschistaceae. The generic name honours Australian lichenologist Rex Filson, "in recognition of his contribution to lichenology, in particular to the lichen flora of Australia".
Huneckia is a genus of crustose lichens in the subfamily Caloplacoideae of the family Teloschistaceae. It has four species.
Golubkovia is a single-species fungal genus in the family Teloschistaceae. It contains the species Golubkovia trachyphylla, a rock-dwelling lichen that is found in Asia and North America. This crustose lichen has a yellow-orange thallus that is placodioid in form.
Gallowayella hasseana, the poplar sunburst lichen, is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. It occurs in North America.
Tassiloa is a genus of lichen-forming fungi in the family Teloschistaceae. It has two species.
Rusavskia is a genus of lichen-forming fungi in the family Teloschistaceae. It has 12 species. It is a member of the subfamily Xanthorioideae. The thallus of Rusavskia is characterized by its foliose (leaf-like) structure with distinct and typically narrow lobes that curve outwards.
Martinjahnsia is a single-species fungal genus in the family Teloschistaceae. It contains the sole species Martinjahnsia resendei, a saxicolous (rock-dwelling) crustose lichen.
Gallowayella fulva is a species of foliose lichen in the family Teloschistaceae. It was first scientifically described in 1796 by German lichenologist Georg Franz Hoffmann, who classified it as a member of genus Lobaria. It has also been classified in the genera Oxneria, Xanthomendoza and Xanthoria in its taxonomic history. Sergey Kondratyuk and colleagues transferred the taxon to the genus Gallowayella in 2012, based on a molecular phylogenetics-based restructuring of some genera in the subfamily Xanthorioideae of family Teloschistaceae. In North America, one vernacular name for the species is the bare-bottomed sunburst lichen.
Xanthoria yorkensis is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. Found in South Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk and Ingvar Kärnefelt. The type specimen, collected along the Maitland road in Yorke Peninsula, was found growing on Melaleuca trees in mallee scrub. The species epithet refers to its type locality, the only place the lichen is known to occur. Kondratyuk and colleagues proposed to transfer the taxon to the newly circumscribed Jackelixia in 2009, but this genus has not been widely accepted by other authorities.
Gallowayella montana is a species of corticolous (bark-dwelling) lichen in the family Teloschistaceae. It occurs in North America.
Marchantiana is a genus of lichen-forming fungi in the family Teloschistaceae. It contains seven species of corticolous (bark-dwelling), crustose lichens that occur in the Southern Hemisphere.
Eilifdahlia is a genus of lichen-forming fungi in the family Teloschistaceae. It contains three species of corticolous (bark-dwelling), crustose lichens that occur in the Southern Hemisphere.
Xanthocarpia jerramungupensis is a species of terricolous (ground-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk, Ingvar Kärnefelt, and John Elix; they classified it in the genus Caloplaca. The type specimen was collected from Jerramungup, Western Australia, where it was found growing among scrub on sandy soil. The species epithet refers to the type locality, which, at the time of its original publication, was the only known location of this lichen. Kondratyuk and colleagues transferred the taxon to the genus Xanthocarpia in 2013, as part of comprehensive molecular phylogenetics-led restructuring of the Teloschistaceae.
Gallowayella weberi is a species of corticolous and saxicolous, foliose lichen in the family Teloschistaceae. Found in the eastern United States, it is a small lichen with a smooth yellow to orange upper surface and a contrasting white lower surface.
Xanthomendoza oregana is a species of corticolous (bark-dwelling), foliose lichen in the family Teloschistaceae. It forms an orange to bright-yellow thallus with ascending lobes that gives it the overall appearance of a tuft. The lichen occurs in western and northern Europe and western North America.
Elenkiniana is a genus of lichen-forming fungi in the family Teloschistaceae. It has three species, all of which occur in Eurasia.
