Description: Thallus crustose, greenish or grey-green, minutely granulose, very thin and often indistinct. Apothecia lecideine, 0.2-0.4 mm across, round to sometimes confluent and irregular in outline, yellowish-brown, red-brown to finally sometimes brown-black, with a concave to finally strongly convex disc and an initially raised, but soon excluded proper margin. Proper exciple pale yellow to dark brown in outer part, more or less colourless in inner part, 40-60(-70) μm thick at base, K-; epithecium pale brown; hymenium colourless, (35-)40-60 μm high, I+ blue; paraphyses not coherent, more or less branched in upper part; hypothecium pale yellow, K-. Asci 8-spored, clavate, with an amyloid, slightly broadening tube-structure, approaching the Psora-type. Ascospores 1-septate, with unequal cells, hyaline, ellipsoid (6-)8-13(-15) x (3-)4-5(-6) μm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
