Description: Thallus crustose, episubstratic, grey-brown, thinly rimose-areolate to verruculose, subeffigurate, delimited by a distinct, zoned, blue-black prothallus. Apothecia lecanorine, at first innate, then sessile and strongly constricted at base, sometimes substipitate, round to angular by mutual compression, with a dark brown, epruinose, flat to finally convex disc, and a thin, finally sometimes excluded thalline margin. Epithecium brown; hymenium colourless, I+ blue; hypothecium colourless. Asci 8-spored, clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, 2-4-times as long as wide, with obtuse ends, often biguttulate, Photobiont chlorococcoid. Spot tests: unknown. Chemistry: unknown.
