Description: Thallus small-squamulose to subcrustose and warted-granular, whitish grey to grey, darker in the centre of the squamules, forming up to 4 cm wide patches, the squamules flattened, crenate to lobulate, smooth, contiguous to more or less overlapping, 0.1-0.5(-1) mm wide, forming a compact crust. Upper cortex 5-10 µm thick, overlain by an epinecral layer; algal layer with scattered groups of algae which are often arranged in columns; medulla white, 15-50 µm thick. Apothecia frequent, lecideine, sessile, often aggregated, 0.3-0.8(-1) mm across, with a black to brown-black, epruinose, at first flat but soon turning convex disc and an indistinct, soon excluded proper margin. Proper exciple of radiating hyphae, pale in outer part, red-brown within, K+ intensifying, N+ purple-red, 40–60 μm wide laterally; epithecium greenish grey to blue-green, K-, N+ reddish, c. 10 μm high; hymenium colourless to partially brownish, 70-90 µm high; paraphyses mostly simple, coherent, stout, (1.5-)2-3 μm thick at mid-level, the apical cells up to 5 μm wide; subhymenium 50-75 μm high, mostly colourless in upper part, pinkish brown to dark brown in lower part; hypothecium brown-red in upper part, paler in lower part. Asci 8-spored, cylindrical-clavate, with a K/I+ blue apical dome penetrated by a narrow, K/I– apical cushion surrounded by an indistinct, apically often tapering, wall K/I– but surrounded by an I+ red-brown, K/I+ blue outer layer. Ascospores (0-)1-3-septate, hyaline, fusiform and pointed at one end, (12-)14-25(-28) x 3-5(-7) µm, with a warted, gelatinous perispore which is visible in water and disappears in K. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: thallus with zeorin.
