Description: Thallus crustose, episubstratic, continuous to faintly rimose, 0.1-0.2 mm thick, pale yellow-grey to ash-grey. Cortex (20-)30-35 µm thick, the upper part brownish-yellow or almost colourless: medulla white, poorly developed, I-. Apothecia lecanorine-aspicilioid, 0.2-0.5 mm across, with a concave to flat, black, epruinose disc, and a slightly prominent, dark thalline margin. Exciple 40-50(-100) µm wide, dark greenish-brown, gradually narrowing downwards, I-; epithecium brownish yellow; hymenium 90-100 µm high, I+ blue, then brownish red: paraphyses sparingly branched, submoniliform, c. 1 µm thick at base, the uppermost cells to 3 µm wide; hypothecium c. 35 µm high, opaque. Asci 8-spored, clavate, the thin outer coat K/I+ blue, the wall and apical dome K/I-. Ascospores 1-celled, hyaline, ellipsoid, 16-18 x 9-10(-12) µm. Pycnidia immersed, with a black to brown, punctiform ostiole and a colourless wall. Conidia bacilliform, straight, 8-10 x c. 0.8 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-. Chemistry: without lichen substances.
