Description: Thallus crustose, episubstratic, continuous and smooth to finely verrucose, rimose or rarely areolate. Apothecia biatorine or lecideine, 0.3-0.5 mm across, broadly sessile, round to irregular in outline, often confluent into 1-1.5 mm wide, tuberculate aggregates, with a greenish blue to blue-black, at first concave, then flat to convex disc, and an initially raised, markedly glossy, finally sometimes excluded proper margin, which, especially when wet, usually appears darker than the disc. Proper exciple colourless or paler in outer part, blackish green to blackish blue and almost carbonized within, K+ blue to green, N+ violet-red; epithecium 5-10 µm high, colourless, greenish-black or dark brown, N+ reddish; hymenium colourless to pale brown or pale green, 50-60 µm high, I+ blue turning red-brown; paraphyses strongly coherent, usually simple, the apical cells not or only slightly swollen, 2-4 µm wide; hypothecium colourless or yellowish brown, 75-100 µm high. Asci 8-spored, clavate, with a K/I+ blue apical dome penetrated by a narrow, K/I- apical cushion surrounded by a narrow, deeply K/I+ blue zone, the wall K/I- but surrounded by an I+ red-brown, K/I+ blue outer layer, the ocular chamber relatively small, Biatora-type. Ascospores 1-celled (rarely 1-septate), hyaline, narrowly ellipsoid, 10-16(-20) x 3-5 µm. Pycnidia black-brown. Conidia 1-celled, bacilliform, 4-6 µm long. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.
