Description: Thallus crustose, whitish to grey-green, continuous, mostly small-granulose to verrucose. Apothecia frequent, biatorine, sessile and constricted at base, 0.4-1.3 mm across, with a grey, dark reddish brown to blackish brown, long concave to flat disc which becomes convex in old apothecia, the margin thin but evident in young apothecia, persistent, only finally excluded, smooth, concolorous with or paler than disc, often somehow shiny. Proper exciple colourless or patchily reddish brown, 65-95 µm wide laterally; epithecium brownish to olive-brown, K-, N-; hymenium colourless, 70-110 µm high; paraphyses simple, coherent, c. 2 µm thick at mid-level, the apical cells slightly wider; hypothecium pale to reddish brown in upper part. Asci 8-spored, cylindrical-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 wal laterally vey thin, K/I- but surrounded by an I+ red-brown, K/I+ blue outer layer, the ocular chamber relatively small, Biatora-type. Ascospores (1-)3(-5)-septate, hyaline, ellipsoid-cylindrical to fusiform, 15-30 x 4-9 µm, without a distinct perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
