Description: Thallus crustose, endosubstratic or episubstratic, continuous to rimose-areolate, yellowish grey, whitish grey or pale brown, usually without a distinct prothallus. Apothecia lecanorine, 1-2.5 mm across,, sessile, rounded or irregular, with a slightly concave to flat, flesh-coloured but densely yellowish- or brownish-grey pruinose disc, and a thick, entire or rarely flexuose, smooth or rough thalline margin. Amphitecium corticate, the cortex laterally thinner and a well-differentiated, vitreous at the base, but opaque; the medulla rich in algal cells; excipular ring or discoid like tissue absent; proper exciple well-developed; hymenium colourless, (160-)220-300 μm high; hypothecium yellowish. Asci (4-)6-8-spored, with thick, amyloid walls, Pertusaria-type. Ascospores 1-celled, hyaline, ellipsoid but often deformed, rather variable in size- 30-80 x (15-)20-43 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC+ pink, P-, UV+ white; medulla C-, KC-; apothecial margins C+ yellow and partially (inner part only) C-, KC+ pink; pruina of the apothecial disc usually C+ yellow. Chemistry: thallus with variolaric acid (major), accompanied by different unknown substances, often with alectoronic acid, and fatty acids of the murolic acid complex.
Note: a cool-temperate to boreal-montane species with optimum on twigs in humid and cold sites; certainly widespread thoughout the Alps. The identification of the sample from Sicily by Brackel (2008c) is not fully certain. The species is included in the Italian red list of epiphytic lichens under the “Least Concern” category (Nascimbene & al. 2013c).
