Description: Thallus crustose, rather thick (0.5-2 mm), smooth to wrinkled or areolate, dull, whitish, ochre-grey or pale brown, forming up to 5 cm wide (usually less) patches. Apothecia lecanorine, round to (more rarely) irregular, 1-3 mm across, with a flat, pink-ochre, finely white-pruinose or rarely epruinose disc and a very thick, smooth, prominent thalline margin. Thalline exciple corticate, the cortex well-developed, in upper part up to ± 70 µm, ± expanded at the base to 80–100 µm, the medulla well-developed; proper exciple well visible in section, superficially often forming a ring around disc; epithecium pale brown; hymenium colourless, 250-300 μm high; paraphyses thin, slender, densely branched and anastomosing; hypothecium colourless to yellowish. Asci (4-)6-8-spored, with thick, amyloid walls, without recognizable apical structures, Pertusaria-like. Ascospores 1-celled, hyaline, broadly ellipsoid, (35-)45-70(-75) x (12-)25-40 µm. Photobiont: chlorococcoid. Spot tests: cortex K-, C- or C+ yellow, KC+ yellow, P-; epithecium C+ red, the pruina C- or C+ yellow; medulla of the apothecial margin C- or very rarely C+ red in basal part, KC- or entirely or partly KC+ pink-red. Chemistry: epithecium with gyrophoric and lecanoric acid, thallus with variolaric acid, occasionally with substances of the murolic acid complex; alectoronic acid sometimes present in the medulla of the apothecial margin only.
