Description: Thallus crustose, up to 0.6 mm thick, granular to irregularly areolate, white to pale grey, usually pruinose, the areoles, when developed, 0.3-1.5 mm wide, flat, smooth, corticate, the cortex c. 15–20 μm thick. Apothecia lecanorine, scattered and rounded to crowded and slightly deformed, broadly sessile, up to 0.8(-1) 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). Thalline exciple 70–100 μm thick, cupular, densely packed with photobiont cells, with a 15–20 μm thick, colourless or reddish brown outer layer; epithecium brown- to brown-black-spotted, the pigment sometimes partly extending deeper into hymenium; hymenium colourless below, (50-)55-75(-80) µm high, not inspersed with oil droplets; paraphyses strongly coherent, mostly simple, (1.5-)2-2.5 µm thick, the apical cells strongly clavate, up to 6(-7) µm wide; hypothecium colourless, inspersed with scattered oil droplets, 50-100 µm high. 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-)10-15(-18) x (4-)4.5-5.5(-6) µm, without a gelatinous perispore. Pycnidia rare, immersed, dark-brown or black around the ostiole. Conidia thread-like, mostly strongly curved, 12-20 x c. 0.8 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
