Teloschistales genera

Caloplaca is a lichen genus comprising a number of distinct species. Members of the genus are commonly called firedot lichen, jewel lichen. gold lichens, "orange lichens", but they are not always orange, as in the case of C. albovariegata. The distribution of this lichen genus is worldwide, extending from Antarctica to the high Arctic. It includes a portion of northern North America and the Russian High Arctic. There are about thirty species of Caloplaca in the flora of the British Isles.

Xanthoria is a genus of lichenized fungi in the family Teloschistaceae. Common names include orange lichen, orange wall lichen, and sunburst lichen. They can be identified by their characteristic squamulose morphology with distinctive "fairy cups".

Xanthomendoza is a genus of small, bright orange foliose lichens with lecanorine apothecia. It is in the family Teloschistaceae. Members of the genus are commonly called sunburst lichens or orange lichens because of their bright orange color.

Fulgensia is a fungal genus in the family Teloschistaceae. The genus was circumscribed by Abramo Bartolommeo Massalongo and Giuseppe De Notaris in 1853, with Fulgensia vulgaris assigned as the type species. Although the genus has had several species in it at times in its taxonomic history, it is now monotypic, as most of its former species have been transferred to Gyalolechia or other Teloschistaceae genera.

Seirophora is a genus of lichen-forming fungi in the family Teloschistaceae. It comprises nine species. The genus was erected in 1983, with Seirophora magara assigned as the type species. These lichens form small, shrubby growths with firm, cartilage-like branches that are stiffened by internal cord-like structures and covered with complex surface hairs rather than the simple root-like attachments found in related genera. Several species were transferred to Seirophora in 2004 when the genus was emended by Patrik Frödén and Per Lassen to include some species segregated from Teloschistes.

Megalospora is a genus of lichen-forming fungi in the family Megalosporaceae.

Teloschistes is a genus of lichen-forming fungi in the family Teloschistaceae, of which it is the namesake. Species of Teloschistes are among the most visually striking lichens, typically forming small, bushy, much-branched growths in vivid shades of yellow to orange, colours produced by anthraquinone pigments, particularly parietin. The genus has a worldwide distribution, with species occurring on twigs, bark, and rock surfaces in open, well-lit habitats ranging from coastal scrub and semi-arid shrublands to alpine zones.

Athallia is a genus of lichen-forming fungi in the family Teloschistaceae. Most species have a poorly developed or almost invisible thallus, with the fruiting bodies often appearing to sit directly on the substrate. The genus occurs on bark, wood, and rock, and is found mainly in temperate regions of the Northern Hemisphere. All species share a characteristic set of orange anthraquinone pigments known as  A.

Flavoplaca is a genus of crust-like or scaly lichens in the family Teloschistaceae. It has about 30 species with a mostly Northern Hemisphere distribution. The genus was established in 2013 when genetic studies revealed that these species formed their own distinct evolutionary group, separate from other lichen classifications where they were previously placed. These lichens typically grow on limestone and other calcium-rich rocks, forming distinctive orange to yellow crusty patches that are particularly common in coastal environments and sunny locations. Most species grow directly on rock surf

Gyalolechia is a genus of lichen-forming fungi belonging to the family Teloschistaceae. It contains about 20 species of crustose lichens.

Bryoplaca is a small genus of lichen-forming fungi belonging to the family Teloschistaceae. Established in 2013 by Ulrik Søchting, Patrik Frödén and Ulf Arup, this small genus comprises just three species that specialise in growing on moss-covered substrates in cold regions of the Northern Hemisphere. These lichens are distinguished by their bright orange fruiting that stand out like tiny sunbursts against the mossy cushions they inhabit, earning the genus its name which literally means 'moss-plate'.

genus of fungi

Pyrenodesmia is a genus of lichen-forming fungi in the family Teloschistaceae. The genus currently includes 23 recognized species but is believed to contain many more unnamed taxa. The genus was circumscribed in 1852 by Italian lichenologist Abramo Bartolommeo Massalongo. It is characterised by the complete absence of anthraquinones and the presence of Sedifolia-gray pigments in both the thallus and apothecia. These lichens are typically found in calcareous outcrops in the Northern Hemisphere, with biodiversity centres in the Mediterranean basin, Central Asia, and arid regions of western North

Blastenia is a genus of lichen-forming fungi in the family Teloschistaceae. The genus was established in 1852 by the Italian botanist Abramo Massalongo, who brought together several species that had previously been scattered across different genera. These lichens are characterised by their rust-brown to orange-red fruiting bodies and a thin, crusty growth that often breaks into small plate-like sections. The genus includes around 40 recognised species found primarily in the Mediterranean region and Macaronesia, though some species have spread to other parts of the world.

Kuettlingeria is a genus of saxicolous (rock-dwelling), crustose lichens in the family Teloschistaceae. Species are characterized by a white or gray thallus and the presence of anthraquinones in the apothecial and , with the exception of Kuettlingeria diphyodes, which entirely lacks anthraquinones. First described by Italian botanist Trevisan in 1857, the genus includes 15 recognized species, although it is believed to be more diverse with additional unnamed species. These lichens are predominantly found in the Northern Hemisphere, particularly in the Mediterranean region, and grow on limeston

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 ("spectacular Gaya") honours Dr. Ester Gaya (fl. 2001), a Spanish botanist from the University of Barcelona.

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 characterised by its foliose (leaf-like) structure with distinct and typically narrow that curve outwards.

Ioplaca is a genus of crustose lichens in the family Teloschistaceae. The genus was circumscribed in 1977 by Czech lichenologist Josef Poelt with Ioplaca sphalera assigned as the type species.

Rufoplaca is a genus of lichen-forming fungi in the family Teloschistaceae. The genus is found primarily across the Northern Hemisphere, with most species occurring in Europe and additional records from North America and Asia. These lichens typically grow as thin crusts with orange-red colouration on sun-exposed rocks and other surfaces. The genus was established in 2013 to group together several previously scattered species that genetic studies showed formed a natural evolutionary lineage.

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).

Marchantiana is a genus of lichen-forming fungi in the family Teloschistaceae. It contains seven species of corticolous (bark-dwelling), crustose lichens, recorded mainly from Australia. Originally proposed in 2014, the genus underwent significant revision in 2024 when molecular studies showed it comprised two distinct evolutionary lineages. This led to the creation of the new genus Taedigera to accommodate the cool-temperate species from New Zealand and Patagonia, while Marchantiana was retained for the warmer-climate Australian species. Later DNA-based work has treated Streimanniella as a se

Zeroviella is a genus of lichen-forming fungi in the subfamily Xanthorioideae of the family Teloschistaceae. It has eight saxicolous (rock-dwelling) species. Zeroviella was segregated from Rusavskia, a closely related genus, in 2015.

Variospora is a genus of crustose lichens belonging to the family Teloschistaceae. The genus was established in 2013 when DNA studies revealed that many species previously grouped under the traditional large genus Caloplaca actually belonged to distinct evolutionary lineages. These bright orange lichens are distinguished by their variable ascospore shapes—which can be lemon-shaped, hourglass-shaped, or simply divided by a straight partition—and their distinctive purple reaction when tested with potassium hydroxide solution.

Xanthocarpia is a genus of mostly crustose lichens in the family Teloschistaceae. It has 12 species with a largely Northern Hemisphere distribution.

Polycauliona is a genus of lichen-forming fungi in the family Teloschistaceae.
