Description: Thallus crustose, thinly episubstratic, whitish to whitish grey, smooth to rimose, often delimited by a black prothallus. Medulla I-. Apothecia lecideine, (0.2-)0.4-0.6 mm across, adnate to sessile, with a flat to slightly convex usually epruinose but sometimes thinly white-pruinose disc, and an initially rather thick and prominent, then thinner, rarely finally excluded proper margin. Proper exciple brown to olivaceous, 40-60 µm wide, K- (section!); epithecium brown to olivaceous: hymenium colourless, without oil droplets, 70-90 µm high; paraphyses c. 2 µm thick at mid-level the apical cells (3-)4-5.5 µm wide, brown-pigmented; hypothecium with oil droplets. Asci 8-spored, clavate to cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass), the wall I-, but the thin outer gel I+ blue, Bacidia-type. Ascospores 1-septate, brown, often slightly curved, (12-)14-17(-19) x (5-)5.5-7(-8.5) µm, Callispora-type with a slight subapical wall thickening when young, Buellia-type at maturity, the apices pointed, the wall roughly ornamented, the ontogeny of type C (subapical inner wall thickenings produced before septum formation). Photobiont chlorococcoid. Spot tests: K+ yellow, C-, KC-, P-. Chemistry: thallus with atranorin.
