Description: Thallus crustose, episubstratic, thin to thick, rimose or areolate, the areoles up to 0.6-1 mm wide, flat to wart-like, dark grey, grey-brown to dark copper-brown, dull. Apothecia lecanorine, subimmersed to adnate, abundant, often contiguous and angular by mutual compression, 0.3-0.7(-0.9) mm across, with a dark reddish brown to brown-black, flat to rarely convex disc, a thin, entire, persistent thalline margin and often a parathecial ring within the thalline margin. Thalline exciple corticate, the cortex paraplectenchymatous, 5-10 µm wide, I- or I+ blue; epithecium red-brown; hymenium colourless, 60-100(-120) µm high; paraphyses 1.5-2.5(-3) µm thick at mid-level, not conglutinate, the apical cells up to 3.5-5(-7.5) µm wide, heavily pigmented; hypothecium colourless, 40-80 µm high. Asci 8-spored, cylindrical-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, (15-)17-20(-25) x (7-)8-10(-12) µm, Physconia-type, the wall smooth to minutely warted, the torus always well-developed, with an ontogeny of type A (apical wall thickening after septum formation). Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: zeorin and an unidentified substance (traces).

Note: a mainly temperate lichen, typically lignicolous but also rarely occurring on bark, on basal parts of broad-leaved trees, more rarely of conifers, in open woodlands; exceptionally also found on siliceous rocks; optimum in the montane belt.
