Elenkiniana is a genus of lichen-forming fungi in the family Teloschistaceae.[1] It has three species,[2] all of which occur in Eurasia.[3]
Taxonomy
The genus was circumscribed in 2014 by the lichenologists Sergey Kondratyuk, Ingvar Kärnefelt, John Elix, Arne Thell, and Jae-Seoun Hur. Elenkiniana gloriae is assigned as the type species. The genus name honours the Russian botanist, Alexander Elenkin, "in acknowledgement of his many contributions on cryptogams in northern Eurasia".[3]
According to the authors, Elenkiniana shares similarities with the genus Gyalolechia (formerly known as Fulgensia before Arup and colleagues' 2013 revision of the Teloschistaceae[4]) but is distinguished by its typically lobate thalli, laminal pseudocyphellae across the thallus surface, and the absence of numerous crystals in the cortical layer and Шаблон:Lichengloss inclusions in the hymenium.[3] Despite this, the work "The 2016 classification of lichenized fungi", did not accept Elenkiniana, considering it instead synonymous with Gyalolechia.[5] A similar opinion was expressed by Wilk and colleagues in 2021, who in their work preferred to maintain Arup et al.'s original 2013 classification pending additional research.[6]
Description
Genus Elenkiniana is distinguished by its Шаблон:Lichengloss thallus, with hues ranging from yellow to bright orange or reddish orange. The thalli have pseudocyphellae, which are small, porous areas on the lichen surface that facilitate gas exchange. The Шаблон:Lichengloss of Elenkiniana is described as Шаблон:Lichengloss, indicating a structured arrangement of cells that resembles a palisade and is tightly woven.[3]
The apothecia (fruiting bodies) of Elenkiniana are Шаблон:Lichengloss in form, meaning they have a margin that is similar in colour and texture to the thallus. Within these structures, the Шаблон:Lichengloss (the rim of tissue enclosing the spore-producing layer) is very thin and often indistinct. Шаблон:Lichengloss are Шаблон:Lichengloss (containing two compartments separated by a partition with a hole), and there are typically eight spores per ascus. The conidia, a type of asexual spore, range from Шаблон:Lichengloss (rod-like) to narrowly bacilliform in shape.[3]
A distinctive feature of Elenkiniana lichens is their chemical reaction to a solution of potassium hydroxide (i.e., the K+ spot test), turning purple upon contact. This reaction is due to the presence of anthraquinones, specifically those of the parietin and fragilin Шаблон:Lichengloss, as well as depsidones.[3]
