Description: Thallus crustose, thin, usually continuous to cracked, rarely tuberculate, whitish-grey or grey, sometimes delimited by a thick, zoned, white to brownish-pink prothallus. Soralia small, <0.5 mm diam., often excavate and in lines, more rarely plane to convex, orbicular to irregular, usually discrete, sometimes confluent. Soralia granular, 40-60(-75) µm wide, white-grey to grey, sometimes with a brownish tinge, usually paler than thallus. Apothecia rare, lecanorine, 0.5-2 mm across, with a flesh-coloured, densely white-pruinose, first concave then flat disc surrounded by a salmon-pink discoid tissue, and by a thick, wrinkled, usually sorediate thalline margin. Asci 4-6-spored with thick, amyloid walls, Pertusaria-type. Ascospores 1-celled, hyaline, thin walled, 40-50 x 20-25 µm. Spot tests: soralia K-, C+ yellow, KC+ orange or pale yellow, P-, UV+ glaucous with an orange tinge; apothecial disc C+ red. Chemistry: variolaric acid in the medulla, gyrophoric and lecanoric acid in the apothecia.
