The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family, estimated to contain over 1800 species, was extensively revised in 2013, including the creation or resurrection of 31 genera. It contains three subfamilies: Xanthorioideae, Caloplacoideae, and Teloschistoideae. A fourth subfamily, Brownlielloideae, proposed in 2015, has been shown to be part of the Teloschistoideae.
Candelariaceae is a family of lichen-forming fungi in the order Candelariales. It contains seven genera and about 73 species. The family was circumscribed by Finnish lichenologist Rainar Hakulinen in 1954 to contain the type genus, Candelaria.
Candelaria is a genus of lichen-forming fungi in the family Candelariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852.
Candelariella is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with Candelariella vitellina assigned as the type species.
Jan Eric Ingvar Kärnefelt is a Swedish lichenologist.
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.
Igneoplaca is a genus in the subfamily Xanthorioideae of the family Teloschistaceae. It contains a single species, the crustose lichen Igneoplaca ignea.
Sedelnikovaea is a genus of placodioid lichens in the family Lecanoraceae. The genus was circumscribed in 2015 by Sergey Kondratyuk, Min-Hye Jeong, and Jae-Seoun Hur to contain Sedelnikovaea baicalensis, the type species. Three additional species were transferred into the genus in 2019.
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.
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.
Sirenophila is a genus of crustose lichens in the subfamily Teloschistoideae of the family Teloschistaceae. It has four species with an Australasian distribution.
Dibaeis yurii is a little-known species of terricolous (ground-dwelling) lichen in the family Icmadophilaceae. It is found in the Russian Far East and in South Korea.
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".
Bryostigma is a genus of lichen-forming fungi of uncertain familial placement in the order Arthoniales. The genus was circumscribed in 1979 by Josef Poelt and Peter Döbbeler, with the muscicolous lichen Bryostigma leucodontis assigned as the type species. A dozen Arthonia species were transferred into the genus in 2020 following molecular phylogenetic analysis of the family Arthoniaceae that showed distinct phylogenetic lineages that were basal to that family. The genus contains several parasitic species that occur on hosts having chlorococcoid photobionts.
Kashiwadia is a genus of lichen-forming fungi in the family Physciaceae. The genus was circumscribed in Sergey Kondratyuk, László Lőkös, and Jae-Seoun Hur in 2014 to contain the species Physcia orientalis, after molecular phylogenetic analysis showed that the taxon occupied an isolated phylogenetic position in the Physciaceae. An additional five species were added to the genus in 2021. The genus name honours Japanese lichenologist Hiroyuki Kashiwadani, who originally described the type species.
Wetmoreana is a genus of lichen-forming fungi in the family Teloschistaceae. It has two crustose, saxicolous (rock-dwelling) species.
Candelinella is a genus of lichen-forming fungi in the family Candelariaceae. It contains two species of crustose lichens. It is visually similar to the genus Candelina but has unique features, including a distinct thallus and unique spore structures. It was established by Sergey Kondratyuk in 2020, with Candelinella makarevichiae assigned as the type species. The genus is distinguished by the small, crustose thallus that ranges from a granular to areolate or squamulose texture, and the simple to 1-septate, narrowly ellipsoid to oblong ascospores. Its lack of a lower cortex and medulla further sets it apart from Candelina.
Opeltiella is a genus of lichen-forming fungi in the family Candelariaceae. The genus, established by Sergey Kondratyuk in 2020, has four species. It is differentiated from the similar genus Candelaria by its unique features such as eight-spored asci and absence of a lower cortical layer and true rhizines. The genus is characterised by its areolate to more or less squamulose or foliose thallus and the unique chemical substances it contains, such as calycin, pulvinic and vulpinic acids, and pulvinic acid lactone.
