Description: Thallus endosubstratic or very thinly episubstratic, usually poorly evident, whitish to grey. Apothecia initially lecanorine and immersed in thallus, becoming cryptolecanorine and sessile, with a dark brown to black, 0.2-0.4(-0.6) mm wide, concave to flat disc and a thin, whitish, rapidly excluded thalline margin; proper margin thick, prominent and entire at first, becoming thinner with age, usually persistent. Epithecium reddish brown; hymenium colourless, 60-80 µm high; hypothecium colourless. Asci 8-spored, narrowly clavate to clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, pale brown, thin-walled throughout, 12-18 x 5-7.5 µm, Rinodinella-type, the wall not ornamented, the septum very thin (1 μm or less), with ontogeny of type A. Conidia bacilliform, 5-6 x c. 1 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
