Description: Thallus foliose, heteromerous, dorsiventral, adnate to loosely adnate, sometimes pulvinate, up to 10 cm in diam., sorediate. Lobes discrete to imbricate, (0.5-)1-3(-4) mm wide, flat to weakly convex, the upper surface olive-brown to dark brown or blackening, sometimes paler at the periphery, smooth to weakly pitted on lobe-ends, often rather strongly fissured and/or rugose in central parts, dull or rather shiny near the periphery, with laminal, whitish to greyish, punctiform to elongated pseudocyphellae, and granular to weakly isidioid soredia arranged in pale to brown, marginal or laminal, punctiform to capitate soralia partly arising from pseudocyphellae. Lower surface dark brown to black, paler on the lobe ends; with scattered, simple, dark rhizines. Upper cortex paraplectenchymatous, with a non-pored epicortex, the cell walls containing isolichenan; medulla white; lower cortex paraplectenchymatous. Apothecia rather frequent, lecanorine, up to 6 mm across, sessile to short-stipitate, with a concave to flat disc, and an entire to weakly crenate, pseudocyphellate and often sorediate thalline margin. Epithecium brown; hymenium and hypothecium colourless. Asci 8-spored, clavate, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 8-11 x 4.5-7 µm. Pycnidia common, black, mainly laminal, immersed. Conidia bacilliform to bifusiform, 5-7 x c. 1 µm. Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC-, P-, N-; medulla K-, C+ pink, KC+ pink-red, P-, UV-. Chemistry: medulla with gyrophoric acid (major), plus other minor substances.
