Description: Thallus crustose usually endosubstratic and poorly evident, rarely very thinly episubstratic and then whitish to pale grey, without a distinct prothallus. Apothecia initially lecanorine, but rapidly becoming pseudolecanorine, immersed in the rock to subsessile, 0.5-0.8(-1) mm across, with a flat to slightly convex, dark brown to black disc, a very thin, soon excluded thalline margin, and a rather thick, entire, persistent proper margin. Thalline exciple dark brown in outer part, pale brown within; proper exciple densely inspersed with oil droplets; epithecium reddish brown, K-; hymenium colourless, 100-140 μm high, inspersed with oil droplets; paraphyses 1.5-2 μm thick at mid-level the apical cells 4-5 μm wide, with a brown cap; hypothecium colourless, inspersed with abundant oil droplets. 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 18-24 x (10-)12-16 μm, Tunicata-type, with a thick outer wall, the lumina thus appearing double-walled, the torus absent, with ontogeny of type A. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances. Note: a Mediterranean to mild-temperate lichen found on compact, pure limestone or dolomite at relatively low elevations; probably more widespread in Southern Italy.
