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.

Taxonomy

Caloplaca kedrovopadensis was formally described as a new species in 2014 by lichenologists Sergei Kondratyuk and Jae-Seoun Hur. The type specimen was collected by the authors from the Land of the Leopard National Park in Khasansky District (Primorsky Krai). There, at an altitude of 163 m (535 ft), on a slope in a deciduous forest, the lichen was found growing on silicate rocks. It is only known from the type locality; the species epithet refers to the Kedrovaya Pad Nature Reserve, which contains the type locality.^[1]

Description

The crustose thallus of Caloplaca kedrovopadensis is thin, continuous to cracked, and greenish-yellow in colour. It has many apothecia (spore-bearing structures), which measure 0.3–0.55 mm in diameter. Its asci can hold eight spores, but they often instead have 1, 2, 4, or sometimes 6 of the mature, bipolar spores. These ascospores are spindle-shaped (fusiform) with tapered ends, split into two cells by a central septum (hence, "bipolar"), and measure 19–26 by 8.5–10 μm.^[1]

Habitat and distribution

Caloplaca kedrovopadensis was first recorded from the Kedrovaya Pad Nature Reserve in Russia, and a few years later, from the Jiri Mountain of South Korea, at an altitude of 1,314 m (4,311 ft). Both of the Korean collections were found growing on bark.^[2]^[3] Phaeophyscia exornatula , Verrucaria species, and Aspicilia species are other lichens that have been noted to grow in close association with Caloplaca kedrovopadensis.^[1]

The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Many members of the Teloschistaceae are readily identifiable by their vibrant orange to yellow hue, a result of its frequent anthraquinone content. The presence of these anthraquinone pigments, which confer protection from ultraviolet light, enabled this group to expand from shaded forest habitats to harsher environmental conditions of sunny and arid ecosystems during the Late Cretaceous. Collectively, the family has a cosmopolitan distribution, although members occur predominantly in subtropical and temperate regions. Although most members either live on rock or on bark, about 40 species are lichenicolous–meaning they live on other lichens.

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.

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.

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.

Gyalecta ancistrospora is a species of saxicolous (rock-dwelling), crustose lichen in the family Gyalectaceae. Found in Korea, it was formally described as a new species in 2014 by lichenologists André Aptroot and Kwang-Hee Moon. The type specimen was collected by the first author from Mount Juwang at an altitude between 330 and 520 m ; there, it was found growing on siliceous rock. It is only known to occur in this area, where it grows on boulders shaded by trees in forest.

Verseghya is a genus of lichen-forming fungi in the family Pertusariaceae. It has two species. The genus was circumscribed in 2016 by lichenologists Sergey Kondratyuk, Laszlo Lőkös, and Jae-Seoun Hur, with Verseghya klarae assigned as the type species. This crustose species is found in South Korea, where it grows on the bark of a wide variety of both deciduous and coniferous trees. Molecular phylogenetic analysis showed that Verseghya klarae occupied a separate phylogenetic branch in the Pertusariaceae, situated between the genera Ochrolechia and Pertusaria and the Lecanora subcarnea species complex. Verseghya thysanophora was transferred to the genus in 2019. It is widely distributed in the Northern Hemisphere.
