Thallus roughened-granular, greyish-white, areolate-cracked, areolae minute, convex, subangular to subirregular, in patches 2-5(-10) cm diam.Apothecia sessile, crowded to scattered, round to irregular-deformed through mutual pressure, 0.2-2.5 mm diam., ± plane or undulate, disc brownish or brown-red, densely or finely grey-pruinose, margins persistent, entire, flexuose, or sinuous-undulate, concolorous with thallus, paler or ± pinkish. Epithecium granular, grey-brown or yellowish-brown 10-13 µm thick. Hymenium colourless 110-150 µm tall, pale yellowish. Asci clavate. Ascospores 2-3 seriate, broadly ellipsoid, apices rounded, straight, 13-15 × 6.8-9 µm. Chemistry: Atranorin, salazinic (K+ yellow → red) and norstictic (tr.) acids.

Thallus conspicuous, creamish-buff or dingy white or pinkish, or rusty brown-whitish, matt, slightly roughened, continuous, smooth, finely areolate-cracked, in parts ± eroded, areolae angular, plane 1-2 mm diam., in spreading patches, 2-6(-10) cm diam. Apothecia innate to sessile, solitary to 1-5(-10) crowded together, 0.1-1.5 mm diam., subconcave to plane to subconvex, rounded to angular-irregular through mutual pressure, undulate to ± irregular, disc pale to dark red-brown, epruinose or with a faint, white pruina in parts, margins entire to crenulate, concolorous with thallus. Epithecium granular, brownish, 5-7 µm thick. Hymenium colourless or pale straw-coloured, 50-60 µm tall. Paraphyses simple, dense, 1.5 µm thick, apices not capitate. Ascospores oval to ellipsoid 10-14 × 6-9 µm. Chemistry: Cortex K+ yellow (r) red, KC+ red, Pd+ orange. Norstictic and salazinic (tr.) acids, atranorin and chloratranorin.
