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.
Ikaeria is a genus of two species of crustose lichens in the family Teloschistaceae. Both species grow on twig bark of shrubs and trees. It was circumscribed in 2017 by lichenologists Sergey Kondratyuk, Dalip Kumar Upreti, and Jae-Seoun Hur, with Ikaeria aurantiellina assigned as the type species. This lichen was previously placed in the genus Caloplaca, but molecular phylogenetic analysis showed that it belonged in a lineage that was genetically distinct from that genus. Ikaeria serusiauxii was added to the genus in 2020.
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.
Brownliella is a genus of crustose lichens in the subfamily Teloschistoideae of the family Teloschistaceae. It has two 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.
Caloplaca kedrovopadensis is a little-known species of crustose lichen in the family Teloschistaceae. It is only found in the Kedrovaya Pad Nature Reserve in the Russian Far East, and on the Jiri Mountain of South Korea. The lichen has been recorded growing on rocks and on bark.
Lecanora ussuriensis is a species of saxicolous (rock-dwelling) lichen in the family Lecanoraceae. It is found in single localities in the Primorsky Krai region of the Russian Far East, as well as in Japan.
Alfred Mycolayovych Oxner was a Ukrainian botanist and lichenologist. His research covered various areas: floristics, taxonomy, phylogenetics, phytogeography, and phytosociology. Oxner founded the National Lichenological Herbarium of Ukraine.
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.
Tomnashia is a genus of lichen-forming fungi in the family Teloschistaceae. It has four species of saxicolous (rock-dwelling), crustose lichens that occur in southwestern North America.
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.
Opeltia is a genus of lichen-forming fungi in the family Teloschistaceae. It has four species of corticolous (bark-dwelling), crustose lichens.
Rusavskia indochinensis is a species of saxicolous (rock-dwelling) lichen in the family Teloschistaceae. It occurs in India and China.
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.
Xanthaptychia is a genus of lichen-forming fungi in the family Teloschistaceae. The genus, circumscribed in 2017, has three corticolous (bark-dwelling) species.
Gintarasiella is a single-species genus in the fungal family Teloschistaceae. It contains the species Gintarasiella aggregata, a saxicolous (rock-dwelling), crustose lichen that is found in Australia. The lichen forms uneven, pillow-like patches up to 30 mm across, distinguished by its yellow-orange areoles that are tightly packed or spread out and soon covered by many apothecia. These fruiting bodies start as zeorine in form and later become biatorine, ranging from 0.3 to 1 mm wide and often appearing distorted due to their dense clustering.
Tomnashia luteominia, the red firedot lichen, is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed along the North American west coast. The lichen has two varieties: var. bolanderi has distinctive red apothecia, while var. luteominia has orange-brown apothecia.
Oxneriopsis is a genus of lichen-forming fungi in the family Teloschistaceae. It has four species of corticolous (bark-dwelling), crustose lichens.
Lazarenkoiopsis is a single-species fungal genus in the family Teloschistaceae. It contains Lazarenkoiopsis ussuriensis, a corticolous (bark-dwelling), crustose lichen species found in the Russian Far East.
Hanstrassia lenae is a species of saxicolous (rock-dwelling) in the family Teloschistaceae. Described as a new species in 2007, the lichen is found in Russian Far East, Mongolia, and Siberia. It closely resembles Elenkiniana ehrenbergii but distinguished by the presence of soralia on its thallus. This species has a thick, effigurate thallus with weak marginal lobes and developed marginal, labriform (lip-shaped) soralia.
Nevilleiella marchantii 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 2007. The thallus of Nevilleiella marchantii spreads 1–3 cm wide, with distinctive, almost spherical, pustule-like formations that give it an appearance resembling a bunch of grapes. These formations vary in shape and colour from yellow-brown to orange-brown.
