Шаблон:Short description Шаблон:Speciesbox
Golubkovia is a single-species fungal genus in the family Teloschistaceae. It contains the species Golubkovia trachyphylla, a rock-dwelling lichen that is found in Asia and North America. This crustose lichen has a yellow-orange thallus that is placodioid in form (i.e., comprising Шаблон:Lichengloss that radiate out from a centre).
Taxonomy
The genus was circumscribed in 2014 by the lichenologists 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".[1] In North America, "sunny straps" is one vernacular name that has been proposed for the species.[2]
Golubkovia belongs to a clade contains the genus Xanthomendoza, with which it shares the characteristic of having a well-developed, thick layer of plectenchyma in the medulla. Unlike Xanthomendoza, Golubkovia does not have a lower cortical layer, it has an upper cortical layer that is Шаблон:Lichengloss, and it has a Шаблон:Lichengloss Шаблон:Lichengloss (the ring-shaped layer surrounding the hymenium). Additionally, the lichen is attached differently to its substrate.[1]
Habitat and distribution
Golubkovia trachyphylla is a widely distributed lichen found in Asia and North America, where it grows on rocks in arid habitat.[1] It does not show any Шаблон:Lichengloss preference for calcareous or non-calcareous rocks.[2] It has a yellow-orange, crustose thallus that is placodioid in form (i.e., comprising Шаблон:Lichengloss that radiate out from a centre).[1]
Chemistry
It contains emodin, fallacinal, parietin, parietinic acid, and teloschistin as lichen products, and its cortex reacts K+ (purple) in chemical spot testing.[2]
