Olegblumia is a monotypic fungal genus in the family Teloschistaceae. [2] It contains the single species Olegblumia demissa, a saxicolous (rock-dwelling) crustose lichen.
Genus Olegblumia was first circumscribed in 2015 by lichenologists Sergey Kondratyuk, Laszlo Lőkös, and Jae-Seoun Hur. [3] However, the name was not validly published according to the rules of botanical nomenclature as set out in the International Code of Nomenclature for algae, fungi, and plants. [4] The name was validly published by the same authors in 2020. [5] The genus name honours Ukrainian lichenologist Oleg Blum. [4] In molecular phylogenetic analysis, Olegblumia is a sister group to the genus Usnochroma . [5]
Genus Olegblumia is characterized by a lobate thallus that typically forms a distinct, rosette-like shape. The colour of the upper surface of the lichen ranges from brown to brownish-grey. Its lobes are flat to slightly convex and are quite narrow. Soralia, the reproductive structures where soredia are produced, are found on the laminal surface and are noteworthy for their convex shape and highly uplifted soredious mass, which bears a brownish hue. The soredia themselves are irregularly rounded with a colouration that varies from brown to brownish-green. Chemically, Olegblumia contains the lichen products vicanicin and caloploicin. [3]
Found in Europe and North America, Olegblumia demissa grows on siliceous rocks, typically on vertical and inclined surfaces. Aspicilia contorta is a frequent lichen associate. [3]
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 their 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 are lichens that either live on rock or on bark, about 40 species are lichenicolous fungi–meaning they live on other lichens.
The Physciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. A 2016 estimate placed 19 genera and 601 species in the family.
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.
Sedelnikovaea is a genus of placodioid lichens in the family Lecanoraceae. The genus was circumscribed in 2015 by Sergey Kondratyuk, Min-Hye Jeong, and Jae-Seoun Hur to contain Sedelnikovaea baicalensis, the type species. Three additional species were transferred into the genus in 2019.
Dibaeis yurii is a little-known species of terricolous (ground-dwelling) lichen in the family Icmadophilaceae. It is found in the Russian Far East and in South Korea.
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.
Golubkovia is a single-species genus in the family Teloschistaceae. It contains the species Golubkovia trachyphylla, a crustose lichen. The genus was circumscribed in 2014 by Sergey Kondratyuk, Ingvar Kärnefelt, John Elix, Arne Thell, and Jae-Seoun Hur. The generic name honours Russian lichenologist Nina Golubkova (1932–2009), who, according to the authors, "made important contributions to lichenology in northern Eurasia".
Kashiwadia is a genus of lichen-forming fungi in the family Physciaceae. The genus was circumscribed in Sergey Kondratyuk, László Lőkös, and Jae-Seoun Hur in 2014 to contain the species Physcia orientalis, after molecular phylogenetic analysis showed that the taxon occupied an isolated phylogenetic position in the Physciaceae. An additional five species were added to the genus in 2021. The genus name honours Japanese lichenologist Hiroyuki Kashiwadani, who originally described the type species.
Wetmoreana is a genus of lichen-forming fungi in the family Teloschistaceae. It has two crustose, saxicolous (rock-dwelling) species.
Opeltiella fibrosoides is a species of lichen-forming fungus in the family Candelariaceae. It is known to occur only in a single location in Peru, where lichen thrives in a high-altitude environment, specifically on shrubs and cacti in an open pasture land. It was formally described as a new species by Swedish lichenologists Martin Westberg and Patrik Frödén in 2007, first as a member of the genus Candelaria. Although it bears a striking resemblance to C. fibrosa on the surface, it is differentiated by its eight-spored asci and a thallus featuring an ecorticate lower surface. In 2020, Sergey Kondratyuk transferred the taxon to the newly circumscribed genus Opeltiella, following molecular phylogenetic-based analysis of the family Candelariaceae.
Tassiloa is a genus of lichen-forming fungi in the family Teloschistaceae. It has two species.
Gondwania is a genus of lichen-forming fungi in the subfamily Xanthorioideae of the family Teloschistaceae. It has three species. The genus was circumscribed by lichenologists Ulrik Søchting, Patrik Frödén, and Ulf Arup. The type species is G. cribrosa, a species that was first named Polycauliona cribrosa by Auguste-Marie Hue in 1909. The genus name refers to the ancestral supercontinent Gondwana.
Opeltia is a genus of lichen-forming fungi in the family Teloschistaceae. It has four species of corticolous (bark-dwelling), crustose lichens.
Cerothallia yarraensis is a species of corticolous (bark-dwelling), crustose 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 Caloplaca yarraensis. Kondratyuk and colleagues transferred it to the genus Cerothallia in 2014.
Fauriea is a genus of lichen-forming fungi in the family Teloschistaceae. The genus, which contains seven species, is a member of the subfamily Caloplacoideae.
Marchantiana is a genus of lichen-forming fungi in the family Teloschistaceae. It contains seven species of corticolous (bark-dwelling), crustose lichens that occur in the Southern Hemisphere.
Verrucoplaca is a monotypic fungal genus in the family Teloschistaceae. It contains the single species Verrucoplaca verruculifera, a widely distributed saxicolous (rock-dwelling), crustose lichen that grows on coastal rocks.
Eilifdahlia is a genus of lichen-forming fungi in the family Teloschistaceae. It contains three species of corticolous (bark-dwelling), crustose lichens that occur in the Southern Hemisphere.
Rehmanniella is a genus of lichen-forming fungi in the family Teloschistaceae. It contains five species of saxicolous (rock-dwelling) crustose lichens. The genus was circumscribed by lichenologists Sergey Kondratyuk and Jae-Seoun Hur in 2018. The genus name honours Polish geographer, geomorphologist, botanist and explorer Anton Rehmann (1840–1917), who collected bryophytes and vascular plants in South Africa. The genus was originally circumscribed with Rehmanniella wirthii assigned as the type and only species. Four additional species were added to the genus in 2020.
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.
