Description: Thallus foliose, heteromerous, dorsiventral, forming regular to irregular, up to 2-3(-4) cm wide rosettes, the lobes linear and discrete to crowded and overlapping, 0.1-0.5(-0.8) mm wide, flat to weakly convex, grey to brown, turning bright green when wet, epruinose but sometimes with a patchy epinecral layer, rarely sparsely to richly lobulate; lower surface black, often brown at lobe-tips, with dense, concolorous, simple rhizines. Upper and lower cortex paraplectenchymatous; medulla white. Apothecia common, lecanorine, to 1 mm across, with a dark disc and an often crenulate or lobulate thalline margin, the lower side often with a crown of dark rhizines. Epithecium brown; hymenium and hypothecium colourless; paraphyses slender, often forked in upper part, the apical cells clavate, with a thin dark cap. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, brown, ellipsoid, 16-23(-27) x 8-10.5 µm, Physcia-type. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: medulla with zeorin.
