Flavoplaca is a genus of crust-like or scaly lichens in the family Teloschistaceae. It has 28 species with a mostly Northern Hemisphere distribution.
Polycauliona is a genus of lichen-forming fungi in the family Teloschistaceae.
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.
Villophora is a genus of lichen-forming fungi in the subfamily Teloschistoideae of the family Teloschistaceae. It has 9 species. The genus was circumscribed in 2013 by Ulrik Søchting, Ulf Arup, and Patrik Frödén. They assigned Villophora isidioclada as the type, and at that time, only species in the genus. This lichen, previously classified in Caloplaca, is found in South America, Antarctica, and some subantarctic islands. Several additional species were added to the genus in 2021. The generic name Villophora means "carrying filaments".
Wetmoreana is a genus of lichen-forming fungi in the family Teloschistaceae. It has two crustose, saxicolous (rock-dwelling) species.
Xanthocarpia feracissima is a species of saxicolous, crustose lichen in the family Teloschistaceae. It was first formally described as a new species in 1953 by Swedish lichenologist Adolf Hugo Magnusson, as a member of the genus Caloplaca. The type specimen was collected in 1939 by John Walter Thomson in Lake Koshkonong, Wisconsin. In the original description, Magnusson notes a similarity to the lichen now known as Gyalolechia flavovirescens, but distinguishes the new species by its lack of a visible thallus, the sordid-reddish color of its discs, and the "unusually narrow" septa of the spores. Patrik Frödén, Ulf Arup, and Ulrik Søchting transferred the taxon to Xanthocarpia in 2013, following molecular phylogenetic analysis of the family Teloschistaceae.
Solitaria is a fungal genus in the family Teloschistaceae. It contains a single species, the corticolous (bark-dwelling), crustose lichen Solitaria chrysophthalma.
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.
Calogaya alaskensis is a species of crustose lichen in the family Teloschistaceae. It was first described as new to science in 2004 by Clifford Wetmore, who placed it in the genus Caloplaca. Ulf Arup and colleagues transferred the taxon to Calogaya in 2013 following a molecular phylogenetics-led restructuring of the Teloschistaceae.
Usnochroma is a genus of lichen-forming fungi in the family Teloschistaceae. It has two species of crustose lichens. The genus was circumscribed in 2013 by lichenologists Ulrik Søchting, Ulf Arup, and Patrik Frödén, with Usnochroma carphineum assigned as the type species. The genus name refers to the yellowish-green colour of the thallus, which is caused by the substance usnic acid. Usnochroma species occur in Macaronesia, South Africa, the Mediterranean Basin, and Algeria.
Leproplaca cirrochroa is a widespread and common species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It grows up to 5 cm across, featuring a placodioid thallus with narrow, finger-like lobes that adhere closely to the surface, showing intricate division and ranging in colour from dirty orange to brownish orange, often with paler, pruinose orange ends.
Cerothallia subluteoalba is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was described as a new species in 2009. This species is distinguished by its numerous bright yellow to soft yellow-orange apothecia, tiny spores with slim dividers (septa), and a barely distinguishable thallus that either fades away or grows inside its host.
Sirenophila maccarthyi is a species of corticolous/lignicolous, crustose lichen in the family Teloschistaceae. It has a thallus that is whitish or greyish, often inconspicuous and not always continuous, which can appear darker or dirty grey near its numerous, clustered apothecia. Sirenophila maccarthyi is distributed across regions including Western Australia, New South Wales, Victoria, Tasmania, and New Zealand, in both coastal and inland habitats. It typically grows on the bark and dead wood of a wide range of trees and shrubs such as Acacia sophorae, Araucaria excelsa, and various Eucalyptus species.
Flavoplaca austrocitrina is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed in Europe, and has also been recorded in South America.
Flavoplaca maritima is a species of crustose lichen in the family Teloschistaceae. It is found in costal areas of Northern, Western, and Southern Europe. It mostly occurs on rocks, but has also been recorded growing on wood.
Parvoplaca tiroliensis is a species of crustose lichen in the family Teloschistaceae, and the type species of the genus Parvoplaca. It is widely distributed, and has been recorded growing on a variety of substrates, including moss, dead plant material, and bone.
Polycauliona coralloides, the coral firedot lichen, is a species of small fruticose (bushy), saxicolous (rock-dwelling) lichen in the family Teloschistaceae. First formally described in 1866, it was later shuffled to a few different genera in its taxonomic history before ending up in Polycauliona, a genus resurrected from taxonomic obscurity in the molecular phylogenetics era. The lichen occurs on seaside rocks in the intertidal spray zone of California and northwestern Mexico. The species is readily recognized due to its distinctive coral-like form–its thallus grows as a tangle of orange, filamentous branches.
Flavoplaca kantvilasii is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2007.
Flavoplaca arcisproxima is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found primarily in the coastal regions of the Crimean Peninsula and the eastern Mediterranean, particularly in Crete, Greece.
