Description: Thallus crustose, episubstratic, inapparent or consisting of more or less scattered, yellowish white, strongly convex, up to 0.5 mm wide areoles developing on moss leaflets. Apothecia usually abundant, lecanorine, scattered to clustered, 0.3-0.7 mm across, broadly sessile or constricted at base, with an initially flat, then slightly convex, pale to dark brown or finally almost black disc, and a thin, smooth, often finally excluded thalline margin. Thalline exciple with relatively few algae, corticate, the cortex 50-75 µm wide in basal parts, consisting of more or less anticlinally oriented, thick-walled hyphae, often inspersed with crystals visible under polarized light, I+ faintly blue; medullary part rather loose, inspersed with crystals; epithecium greenish brown, brown in upper part, K+ greenish, N+ purple, often with crystals dissolving in K and reacting C+ red; hymenium colourless, 50-60 µm high; paraphyses strongly branched, coherent, the apical cells not capitate; hypothecium colourless, up to 70 µm high, I+ blue. Asci 8-spored, clavate, Lecidella-type. Ascospores 1-celled, hyaline, ellipsoid, 7-10 x 4-5 µm. Photobiont chlorococcoid. Spot tests: thallus and apothecial margin K+ yellow, C+ red, KC+ red, P-. Chemistry: alectorialic acid (major), plus traces of barbatic acid.
