Description: Thallus crustose, episubstratic, areolate-subsquamulose, brown or reddish brown, epruinose, the areoles 0.4-3 mm wide, 0.5-1 mm thick, substipitate and distinctly raised from the substrate, usually contiguous, flat to convex, round to angular, with an uneven surface, the lower surface brown to reddish brown, sometimes whitish or blackened. Epicortex 10-40 μm thick; cortex (30-)40-60 μm thick, paraplectenchymatous, the cells c. 3-4 μm wide, the upper layer brown, the lower layer hyaline or golden; algal layer up to 200 thick, thinner beneath the apothecia, uneven, with algal palisades interrupted by c. 40-50 μm wide hyphal bundles which are continuous with the medulla; medulla 100-300 μm thick or more. Apothecia round, 0.5-2 mm across, immersed in the areoles, usually 1 per areole (sometimes 2-3 and confluent into larger clusters), with a reddish brown to black (reddish when wet), epruinose, flat to slightly convex, more or less smooth disc and a raised, thin margin concolorous with thallus or blackened. Proper exciple prosoplectenchymatous, up to 100 μm thick in upper part; epithecium brown, c. 15 μm high; hymenium colourless, (80-)100-120(-140) μm high; paraphyses 2-3 μm thick at base, sometimes expanded at apices; subymenium to 60 μm high, colourless or yellowish; hypothecium colourless, prosoplectenchymatous, thin, c. 15 μm high. Asci 100-200-spored, clavate, the apical dome K/I-, c. 80-90 x 15-25 μm. Ascospores 1-celled, hyaline, ellipsoid to broadly ellipsoid, (3-)4-5.3 x (1.5-)2-3 μm. Pycnidia oval to globose, visible as dark or reddish dots. Conidia simple, hyaline, c. 2 x 1 μm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
