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 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. Collectively, the family has a cosmopolitan distribution, although members occur predominantly in subtropical and temperate regions. Although most members are lichens that either live on rock or on bark, about 40 species are lichenicolous fungi–meaning they live on other lichens.
Flavoplaca is a genus of crust-like or scaly lichens in the family Teloschistaceae. It has 28 species with a mostly Northern Hemisphere distribution.
Igneoplaca is a genus in the subfamily Xanthorioideae of the family Teloschistaceae. It contains a single species, the crustose lichen Igneoplaca ignea.
Fulgogasparrea is a genus of crustose lichens in the subfamily Xanthorioideae of the family Teloschistaceae. It has five species. The genus was circumscribed in 2013, with Fulgogasparrea decipioides assigned as the type species; this lichen had originally been formally described as a species of Caloplaca, and then a couple of years later transferred to Wetmoreana. Six are credited with authorship of the genus: Sergey Kondratyuk, Jeong Min-hye, Ingvar Kärnefelt, John Alan Elix, Arne Thell, and Jae-Seoun Hur. The genus name alludes to the resemblance of the type species with both of the Teloschistaceae genera Fulgensia and Gasparrinia.
Brownliella is a genus of crustose lichens in the subfamily Brownlielloideae of the family Teloschistaceae. It has four species. The genus was circumscribed in 2013 by Sergey Kondratyuk, Ingvar Kärnefelt, John Elix, Arne Thell, and Jae-Seoun Hur, with the widely distributed lichen Brownliella aequata assigned as the type species. The genus contains species formerly referred to as the Caloplaca cinnabarina species group. The generic name honours Australian botanist Sue Brownlie.
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.
Neobrownliella is a genus of crustose lichens in the subfamily Teloschistoideae of the family Teloschistaceae. It has five species. The genus was circumscribed in 2015 by lichenologists Sergey Kondratyuk, Jack Elix, Ingvar Kärnefelt, and Arne Thell, with Neobrownliella brownlieae assigned as the type species. It is a segregate of the large genus Caloplaca. Characteristics of Neobrownliella include a thallus that is continuous or areolate, the presence of anthraquinones as lichen products, a cortical layer with a palisade paraplectenchyma, and the lack of a thick palisade cortical layer on the underside of the thalline exciple. Two species were included in the original circumscription of the genus; an additional three species were added in 2020.
Golubkovia is a single-species genus in the family Teloschistaceae. It contains the species Golubkovia trachyphylla, a crustose lichen. The genus was circumscribed in 2014 by Sergey Kondratyuk, Ingvar Kärnefelt, John Elix, Arne Thell, and Jae-Seoun Hur. The generic name honours Russian lichenologist Nina Golubkova (1932–2009), who, according to the authors, "made important contributions to lichenology in northern Eurasia".
Wetmoreana is a genus of lichen-forming fungi in the family Teloschistaceae. It has two crustose, saxicolous (rock-dwelling) species.
Tassiloa is a genus of lichen-forming fungi in the family Teloschistaceae. It has two species.
Niorma is a genus of lichen-forming fungi in the family Teloschistaceae. It has six fruticose species, with N. derelicta assigned as the type species. The genus was originally proposed by Italian lichenologist Abramo Bartolommeo Massalongo in 1861, but this and several other genera he proposed were largely ignored by later contemporaries. As part of a molecular phylogenetics-led restructuring of the teloschistoid clade of the subfamily Xanthorioideae in the Teloschistaceae, Sergey Kondratyuk and colleagues resurrected the genus for use about 150 years later. Genus Niorma comprises what was previously known as a species complex centred around the taxon previously known as Teloschistes hypoglaucus.
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.
Niorma hosseusiana is a species of corticolous (bark-dwelling), fruticose lichen in the family Teloschistaceae. It is found in South America.
Cerothallia yarraensis is a species of corticolous (bark-dwelling), crustose 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 Caloplaca yarraensis. Kondratyuk and colleagues transferred it to the genus Cerothallia in 2014.
Erichansenia is a genus of lichen-forming fungi in the family Teloschistaceae. It has three species of saxicolous (rock-dwelling), crustose lichens.
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.
Orientophila is a genus of lichen-forming fungi in the family Teloschistaceae. It has 15 species of mostly saxicolous (rock-dwelling), crustose lichens. All Orientophila species occur in Northeast Asia including China, Japan, South Korea, and the Russian Far East.
