Description: Thallus crustose, thin, granular to irregularly areolate, white to pale grey, usually pruinose. Areoles, when developed, 0.3-1.5 mm wide and c. 0.5 mm thick, flat, smooth. Apothecia scattered and rounded to crowded and slightly deformed, broadly sessile, up to 0.8 mm across, with a flat to slightly convex, reddish brown to black, often white-pruinose disc (slightly paler and dark-spotted, with a dark pigmented edge when wet), and a thin, pale grey-white pruinose thalline margin which is often excluded in old apothecia (with a few algal cells restricted to the lower edges of the apothecium). Epithecium brown- to brown-black-spotted, the pigment sometimes partly extending deeper into hymenium; hymenium colourless below, 55-80 µm high; paraphyses strongly conglutinated, unbranched, 2-2.5 µm thick, the apical cells strongly clavate, up to 6 µm wide; hypothecium colourless. Asci 8-spored, clavate, with a K/I+ blue tholus and a central non-amyloid area, Bacidia-type. Ascospores 1-septate, hyaline, ellipsoid or oblong-fusiform, straight, not constricted at septum, thin-walled, (8-)10-13(-15) x (4-)4.5-5.5(-6) µm Pycnidia rare, immersed, dark-brown or black around the ostiole. Conidia filiform, mostly strongly curved, 12-20 x c. 0.8 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: on calcareous rocks, mortar, basic siliceous rocks, brick and roofing tiles, often on man-made substrata, usually below the subalpine belt; probably the most common saxicolous species of the genus in Italy.
