Description: Thallus squamulose to subcrustose-areolate in central parts, often lobed at margins, brown to pale ochraceous yellow in shade-forms, sometimes faintly white-pruinose, thick, the squamules more or less rounded, flattened, smooth, contiguous, usually non imbricate, forming a compact crust, the peripheral ones often elongated and forming short radiating lobes; lower surface dark, attached by a dense mat of blackish to dark brown, 4-5 μm thick rhizohyphae. Upper cortex 30-40 μm thick, paraplectenchymatous, with a 10-20 μm thick epinecral layer; medulla rather loose, white in upper part, brown in lower part, merging with a 50-70 μm thick, brown lower cortex. Apothecia at first immersed and cryptolecanorine, then sessile and clearly lecanorine, up to 1.5 mm across, with a black (reddish brown when wet), sometimes faintly pruinose disc and a thin, smooth, persistent thalline margin. Epithecium 10-20 μm thick, reddish brown; hymenium colourless, 120-140 μm high; paraphyses 1.5-2 μm thick at base, distinctly thickened in upper part (to 3-4 μm), with a brown cap; hypothecium colourless, up to 100 μm high. Asci 8-spored, broadly clavate, with a I+ blue tholus, a broad ocular chamber, and a cylindrical to short-conical axial mass. Ascospores 1-septate, sometimes slightly constricted at septum, brown, ellipsoid, rather thin-walled except sometimes at the ends, 18-22 x 8-10 μm, Buellia-type. Pycnidia rare, globose, immersed. Conidia bacilliform, 5-6 x c. 1 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: variolaric acid, zeorin, and triterpenes.
