Rusavskia
''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 lichen, foliose (leaf-like) structure with distinct and typically narrow that curve outwards. Taxonomy The genus ''Rusavskia'' was proposed by lichenologists Sergey Kondratyuk and Ingvar Kärnefelt in 2003, with ''Rusavskia elegans'' assigned as the type species. The initial circumscription (taxonomy), circumscription of the genus relied predominantly on an evaluation of morphology (biology), morphological, anatomical and chemical characteristics, with a notable absence of molecular phylogenetic analysis. For this reason, the reception of the ''Rusavskia'' by lichenologists was initially met with cautious appraisal. As several molecular studies in the subsequent years showed, the ''Rusavskia elegans''-group occupies a separate monophyletic branch in the Teloschistaceae; t ...

Rusavskia Drevlyanica
''Rusavskia drevlyanica'' is a species of saxicolous (rock-dwelling) lichen in the family Teloschistaceae. Described as a new species in 2020, it is found in the East European forest steppe of Ukraine. Taxonomy The lichen was formally described as a new species in 2020 by the lichenologists Sergey Kondratyuk and Oleksandr Orlov. The species epithet ''drevlyanica'' alludes to its prevalent location, the Drevlyansky Nature Reserve in Ukraine. The type specimen was collected in the vicinity of the Hannivka village ( Zhytomyr Oblast), specifically on the roof of an old sheepfold building. It was found growing along with various other lichen species. Orlov collected the type specimen in October 2018. Earlier taxonomic records had grouped ''Rusavskia drevlyanica'' under ''Rusavskia elegans''. The former's distinct morphological features and habitat preferences, however, warranted its classification as a separate species. Description The thallus of ''Rusavskia drevlyanica'' g ...

Rusavskia Indochinensis
''Rusavskia indochinensis'' is a species of saxicolous (rock-dwelling) lichen in the family Teloschistaceae. It occurs in India and China. Taxonomy ''Rusavskia indochinensis'' was described as a new species in 2020 by lichenologists Sergey Kondratyuk, Gaurav Kumar Mishra, Sanjeeva Nayaka, and Dalip Kumar Upreti. The species epithet ''indochinensis'' refers to the southern part of the Asian continent, which is where this species has been identified. The type specimen was collected in India, specifically in Uttarakhand's Chamoli district, before Malari on the way to Niti at an altitude of . While ''Rusavskia indochinensis'' is categorically part of the ''Rusavskia'' branch based on its Internal transcribed spacer nrDNA phylogeny, its resemblance to species of the genus ''Zeroviella'' suggests the need for more molecular data for precise classification. Chinese specimens, in particular, require further molecular examination to determine their exact status. Description The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rusavskia Elegans
''Rusavskia elegans'' (formerly ''Xanthoria elegans''), commonly known as the elegant sunburst lichen, is a lichenized species of fungus in the genus ''Rusavskia'', family Teloschistaceae. Recognized by its bright orange or red pigmentation, this species grows on rocks, often near bird or rodent perches. It has a circumpolar and alpine distribution. It was one of the first lichens to be used for the rock-face dating method known as lichenometry. Taxonomy ''Rusavskia elegans'' was first formally described by Johann Heinrich Friedrich Link as ''Lichen elegans'' in 1791, and transferred to the genus ''Xanthoria'' by Theodor Magnus Fries (son of Elias Magnus Fries) in 1860. In 2003, Sergey Kondratyuk and Ingvar Kärnefelt transferred the taxon to their newly circumscribed genus ''Rusavskia'', in which it is the type species. Although the new genus was not initially widely accepted, subsequent molecular phylogenetic studies showed the validity of the new classification. Description ...

Teloschistaceae
The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family has a cosmopolitan distribution, although its members occur predominantly in temperate regions. Most members are lichens that either live on rock or on bark, but about 40 species are lichenicolousmeaning they are non-lichenised fungi that live on other lichens. 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. Teloschistaceae lichens typically have one of a few physical growth forms. Depending on the species, the thallus (the main body of the lichen) is either leaf-like ( foliose) ...

Rusavskia Sorediata
''Rusavskia sorediata'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed in the Northern Hemisphere. The lichen was first formally described by the Finnish lichenologist Edvard August Vainio in 1881, as ''Lecanora elegans'' var. ''sorediata''. Gustaf Einar Du Rietz transferred it to ''Caloplaca'' in 1916. Josef Poelt considered it better in genus '' Xanthoria'', and it was known by that binomial for several decades. In 2003, Sergey Kondratyuk and Ingvar Kärnefelt transferred it to their newly circumscribed genus ''Rusavskia''. The lichen develops small, spherical pustules on its surface, which eventually become soredia. These soredia can range in abundance from hardly there to covering nearly the entire thallus surface. Because of the characteristic appearance imparted by these granular propagules, in North America, a common name used for this species is sugared sunburst lichen. ''Rusavskia sorediata'' ha ...

Rusavskia Indica
''Rusavskia indica'' is a species of both corticolous (bark-dwelling) and saxicolous (rock-dwelling) lichen in the family Teloschistaceae.
