Description: Thallus crustose, episubstratic, dark grey-brown, often with a greenish or bluish hue, sometimes forming 1-2.5 mm broad concentric rings where the whitish to dark grey hypothallus is visible, irregularly rimose-areolate, the areoles 0.2-1 mm wide, flat to convex, smooth to verrucose, 0.2-0.4 mm thick. Cortex 25-35 µm thick, reddish brown in upper part; medulla white, I-. Apothecia lecanorine-aspicilioid, 0.2-0.7(-1) mm across, usually of different sizes in the same thallus, often crowded, immersed in convex areoles or somewhat raised, 1-4 per areole, with a concave to flat, black, sometimes slightly pruinose disc, a thin but prominent thalline margin and a distinct, black parathecial ring. Proper exciple to 50 µm thick, olivaceous brown in outer part, I+ pale blue; epithecium olive-brown to dark green, N+ emerald green, K+ brownish; hymenium colourless, 80-100 µm high, I+ yellowish green; paraphyses sparingly branched, anastomosing, submoniliform in upper part, 1.5-2 µm thick at mid-level, the apical cells up to 3.5 µm wide; hypothecium colourless, c. 35 µm high, I+ pale blue. Asci 8-spored, clavate, the thin outer coat K/I+ blue, the wall and the apical dome K/I-. Ascospores 1-celled, hyaline, broadly ellipsoid, (14-)17-20(-24) x 7-13(-15) µm. Pycnidia immersed, flask-shaped, with a dark punctiform ostiole. Conidia bacilliform, straight or rarely curved, 7-8 x c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
