Description: Thallus crustose-subplacodioid to subsquamulose, subleprose, white, pale grey to dark grey in central parts, (0.3-)0.5-1.5 mm thick, well delimited, forming regular, robust up to 8 cm wide rosettes. Marginal lobes well-developed, pruinose, with raised, thick margins, sometimes with subcorticate, paraplectenchymatous patches; hypothallus usually poorly developed, formed by pale brown, hyphae reacting K-; prothallus absent. Central part of thallus coarsely granular, often slightly convex, loosely attached, with a chalky consistency due to rich deposits of calcium oxalate crystals. Granules isidioid, subspherical to ellipsoid, 0.3-0.5(-0.9) mm thick, with a compact outer layer of heavily encrusted hyphae, and no or poorly developed, 40-50 μm long projecting hyphae, eventually dissolving into soredia-like granules. Medulla white, compact; hypothallus compact, composed of tightly intertwined hyphae. Photobiont chlorococcoid. Spot tests: thallus K+ yellow or K-, C-, KC- or KC+ yellow, P+ reddish orange, UV-. Chemistry: chemotype 1: atranorin, protocetraric, fumarprotocetraric and roccellic acids; chemotype 2: atranorin, protocetraric and roccellic acids; chemotype 3: atranorin, fumarprotocetraric and roccellic acids.
