Description: Thallus crustose, pale grey to pale brown, dull, epruinose, areolate, rimose-areolate or granular, up to 0.3 mm thick. Areoles subangular, flat, contiguous, 0.2-0.8 mm wide. Apothecia lecanorine (but thalline margin very soon excluded), sessile or adnate, 0.2-0.4(-0.6) mm across, with a pale beige to dark reddish brown, flat to slightly convex, epruinose disc (when wet becoming darker with a dark pigmented edge) and a thin, smooth margin. Proper exciple colourless or outer part pinkish brown and K+ purple, with narrow, conglutinated hyphae, sometimes with a few algae reaching the lower part, but usually without algae; epithecium colourless to pale brown; hymenium colourless or pale grey and K+ purple in dark apothecia, 45-70 µm high; paraphyses conglutinated in a hyaline gelatinous matrix, simple, 1-1.5 µm thick at base, the apical cells up to 3 µm wide; hypothecium colourless or pale straw-coloured. Asci 8-spored, cylindrical to clavate, with a K/I+ blue tholus and a central non-amyloid area, Bacidia-type. Ascospores (1-)3(-5)-septate, hyaline, narrowly fusiform, (11-)14-21(-28) x 2.5-3 µm. Pycnidia immersed, whitish, sometimes reddish-brown around the ostiole. Conidia filiform, strongly curved, 10-19 x 0.8-1.2 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a mainly temperate species found on rain-sheltered or vertical surfaces of base-rich to calciferous rocks in rather shaded places, such as in woodlands and gorges, sometimes overgrowing epilithic mosses, perhaps more widespread in Italy.
