Polycauliona is a genus of lichen-forming fungi in the family Teloschistaceae.
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.
Ikaeria serusiauxii is a species of crustose lichen in the family Teloschistaceae. It is found in the Madeira Archipelago and Canary Islands (Macaronesia), as well as in coastal regions of Algarve and Estremadura in mainland Portugal, where it grows on twigs and branches of trees and shrubs. It was described as a new species in 2020 by lichenologist Harrie Sipman. The type specimen was found on Porto Santo Island, on the lower slopes of Pico do Facho, at an altitude of about 350 m (1,150 ft). Here it was growing on fallen pine trees. The specific epithet honours Belgian lichenologist Emmanuël Sérusiaux, "who contributed significantly to the exploration of the lichen diversity of Macaronesia".
Caloplaca wallabyensis is a species of crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2010 by lichenologists John Alan Elix, Sergey Kondratyuk, and Ingvar Kärnefelt. The type specimen was collected by Elix in Western Australia's Wallaby Hills Nature Reserve, for which the species is named. Here it was found growing on an old termite mound in Eucalyptus salmonophloia woodland with Xanthorrhoea shrubs and laterite rocks. It is known only from the type locality, where it is common.
Lendemeriella is a genus of crustose lichens in the subfamily Caloplacoideae of the family Teloschistaceae. It has nine species. The genus was circumscribed in 2020 by Sergey Kondratyuk, with Lendemeriella reptans assigned as the type species. The genus name honours the American lichenologist James Lendemer, who co-authored the type species in 2012.
Polycauliona comandorica is a species of fruticulose lichen in the family Teloschistaceae. It was formally described as a new species in 2021 by Dmitry Himelbrant, Irina Stepanchikova, and Ivan Frolov.
Lendemeriella aureopruinosa is a species of crustose lichen in the family Teloschistaceae. Found in the Russian Far East, it was formally described as a new species in 2021 by Ivan Frolov, Jan Vondrák, Ulf Arup, Liudmila Konoreva, and Sergey Chesnokov, Lidia Yakovchenko, and Evgeny Davydov. The type specimen was collected on the banks of River Bes-Yuryakh ; here it was found growing on siliceous outcrops in a forest comprising largely birch, alder, and larch trees. The thallus of the lichen ranges in form from an inconspicuous grey film to a more well-developed crust or areoles. Its apothecia measure 0.3–0.6 mm in diameter and have a dark-orange to brick-red coloured disc. Secondary chemicals detected in the lichen include parietin, parietinic acid, emodin, teloschistin, and fallacinal. The specific epithet aureopruinosa refers to the bright gold-coloured pruina that is found on young apothecia.
Kaernefia is a genus of crustose lichens in the family Teloschistaceae. It has three species, found in Australia or South Africa.
Caloplaca ahtii is a species of corticolous (bark-dwelling) crustose lichen in the family Teloschistaceae. Found in Europe, it was formally described as a new species in 1994 by Ulrik Søchting. The type locality was in Finland, and the type specimen was found growing on Populus. The species epithet honours Finnish lichenologist Teuvo Ahti. In 2022, the species was documented from North-Western European Russia. It is also found in North America.
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.
Opegrapha verseghyklarae is a little-known species of lichenicolous (lichen-eating) fungus in the family Teloschistaceae. It is found in the Russian Far East, where it grows on the thalli and apothecia of the crustose lichen Ochrolechia pallescens.
Oxneria ussuriensis is a species of corticolous, crustose lichen in the family Teloschistaceae. It is found in a single location in the Russian Far East.
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.
Variospora cancarixiticola is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in southeastern Spain, where it grows on cancarixite, a volcanic rock known only to occur in that country.
Lichenopeltella coppinsii is a species of lichenicolous fungus belonging to the class Dothideomycetes. It was described in 1999. It is known to infect Verrucaria muralis and has been reported from the British Isles, Ukraine, and Moshchny Island in the Baltic sea.
