Description: Thallus crustose, episubstratic, continuous to rimose, grey, sometimes with a pale yellowish brown tinge towards the centre, 1.5-4 mm thick, well-delimited, isidiate, forming patches to 12 cm in diam, often with a whitish prothallus. Medulla white, not amyloid. lsidia abundant, cylindrical or tapering from base, simple or coralloid, up to 1.5(-2) mm high, 0.1-0.3 mm thick, irregularly oriented. Apothecia very rare, immersed in number of 2-4(-10) into heavily pruinose, up to 1.5(-2) mm wide thalline warts which are constricted at base; disc at first punctiform, later more or less expanded and 0.3-0.5 mm across, pale to dark brown, often faintly white-pruinose. Hymenium colourless, the hymenial gel not or only weakly amyloid; paraphyses lax, branched and richly anastomosing. Asci 2-spored, broadly cylindrical, the apex without a distinct ocular chamber, the outer sheath K/I+ blue, otherwise K/I–, with an inner extensible layer, Pertusaria-type. Ascospores 1-celled, hyaline, ellipsoid, 80-140(-200) x 40-80 μm, the wall 2-3 μm thick, not zoned nor striate. Photobiont chlorococcoid. Spot tests: thallus K+ yellow-orange, C-, KC-+ yellow, P+ yellow-orange, UV-. Chemistry: thamnolic acid.Note: a cool-temperate to boreal-montane lichen found on steeply inclined surfaces of siliceous rocks in rainy areas, where it is sometimes very abundant; most frequent in the Alps, rarer elsewhere, ranging south to the mountains of Sicily.
