Biatora oxneri is a species of corticolous (bark-dwelling) lichen in the family Ramalinaceae. It is found in the Russian Far East and in South Korea.
The species was formally described as new to science in 2015 by lichenologists Sergey Kondratyuk, Laszlo Lőkös, and Jae-Seoun Hur. The type specimen was collected along the Kamenisty stream (Khasan district, Primorsky Krai); there, in a deciduous forest, the lichen was found growing on the bark of a deciduous tree, closely associated with an individual of Ochrolechia pallescens that had itself been damaged by Opegrapha verseghyklarae . The species epithet honours Ukrainian lichenologist Alfred M. Oxner (1898–1973), who, according to the authors, "made important contributions to our current knowledge of Eastern and Northern Asian lichens". [2]
Kondratyuk and colleagues initially placed the taxon in genus Ivanpisutia . Christian Printzen and Sonja Kistenich transferred the taxon to Biatora in 2018 following a comprehensive molecular phylogenetics-based reorganisation of the family Ramalinaceae. [3]
Biatora oxneri has a whitish to whitish-grey crustose thallus that is 2–3 cm (0.8–1.2 in) across, although neighbouring thalli may coalesce to form larger spots. A thin (>0.2 mm wide) hypothallus is observed where the thallus border another crustose lichen. The apothecia, which are in a transitional state between biatorine- and byssoid-type, are closely attached to the thallus and measure 0.2–0.9 mm in diameter. The apothecial disc ranges in colour from dark violet to blackish violet to ink blue; it is initially concave or flat, later becoming convex. The asci are of the "Lecanorine"-type and contain eight spores. These ascospores have a shape described as narrowly bacilliform to somewhat lens-like, and measure 8–13 by 2–3.2 μm. [2]
All of the standard chemical spot tests on the thallus are negative, while the N-test (35% solution of nitric acid) produces a violet-purple colour on the hymenium and subhymenium. [2]
Biatora pacifica , described as new to science in 2016 from Sakhalin, is similar in appearance to B. oxneri, and the authors suggest that it may be an esorediate version (i.e., lacking soredia) of this species. [4]
The precise range of Biatora oxneri is not well understood, as it is known only from a few scattered and isolated collections in Sakhalin, Khabarovsk, and Primorsky regions, all in the Russian Far East. [2] In 2018 it was recorded from Jeju Island in South Korea, where it was growing on smooth bark in close association with Mikhtomia gordejevii . [5]
The Ramalinaceae are a family of lichenized fungi in the order Lecanorales. The family name is synonymous with the name Bacidiaceae. Species of this family have a widespread distribution.
Biatora is a genus of lichens in the family Ramalinaceae. First described in 1817, the genus consists of crustose and squamulose lichens with green algal photobionts, biatorine apothecia, colorless, simple to 3-septate ascospores, and bacilliform pycnospores. According to the Dictionary of the Fungi, the genus contains 42 species that are widely distributed in temperate areas.
Bacidina is a genus of lichens in the family Ramalinaceae. It was circumscribed by Czech lichenologist Antonín Vězda in 1990, with Bacidina phacodes assigned as the type species. Vězda included 11 species in Bacidina, which was originally classified in the Lecideaceae. These species had previously been placed in genus Bacidia.
The Pertusariaceae are a family of lichen-forming fungi in the order Pertusariales.
Toniniopsis is a genus of crustose and squamulose lichens in the family Ramalinaceae. The genus was circumscribed by Swiss lichenologist Eduard Frey in 1926, with Toniniopsis obscura designated the type and only species. As a result of molecular phylogenetic studies, several species, formerly classified in genus Bacidia, have been transferred to Toniniopsis.
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.
Agonimia is a genus of lichen-forming fungi in the family Verrucariaceae.
Palicella is a genus of crustose lichens in the family Lecanoraceae. It contains five species.
Coppinsidea is a genus of two species of crustose lichens in the family Ramalinaceae. It was circumscribed in 2019 by lichenologists Sergey Kondratyuk, Edit Farkas, and Laszlo Lőkös with Coppinsidea sphaerella designated as the type species. Species of Coppinsidea are similar in appearance and morphology to Thamnolecania, but differ from them in having a thallus that is crustose (rather than fruticose, mostly convex to almost spherical apothecia that are lecideine or biatorine in structure, as well as in being distributed in the Northern Hemisphere.
Coppinsidea vainioana is a species of crustose lichen in the family Ramalinaceae. It occurs in Europe, where it grows on the bark of pine trees.
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.
Bibbya is a genus of fruticose lichens in the family Ramalinaceae.
Biatora kalbii is a species of squamulose lichen in the family Ramalinaceae. It has a pantropical distribution.
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.
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.
Lecidella mandshurica is a species of corticolous (bark-dwelling), crustose lichen in the family Lecanoraceae. It is found in the Russian Far East, South Korea, and China.
Lecanora lojkahugoi is a species of saxicolous (rock-dwelling) crustose lichen in the family Lecanoraceae. It is found in the Russian Far East and in South Korea.
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.
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.
