A species differing from all the other Czech genus members by the yellowish thallus, containing usnic acid in the cortex. It is an epiphytic lichen with a range extending from the tropics to oceanic areas of the temperate zone on all continents. In central Europe, it occurs rarely in mountains, mainly on spruce and fir branches in localities with a high humidity. In contrast, it is usually found on Alnus glutinosa in Scandinavia. There are only historical records on its occurrence in the Czech Republic, coming from the Šumava, Krušné hory, Krkonoše and Hrubý Jeseník Mountains. Currently, the species is considered extinct.taxonomic classification:
