Description: Thallus mostly endosubstratic, thin and inapparent, whitish grey, probably not lichenised. Apothecia black, epruinose, 0.1-0.3(-0.4) mm across, round to angular, with a concave to slightly convex, epruinose disc sometimes hidden by a very thin, raised and inflexed, most often poorly evident proper margin. Proper exciple black in outer part, paler within, not extending below the hymenium; epithecium brown, inspersed with granules; hymenium colourless to pale brown, 60-75 µm high, I+ pale blue; paraphyses 1-2 µm thick, mostly simple or sparingly branched and anastomosing, thread-like, the apical cells brown, to 4 µm wide; hypothecium colourless to pale yellowish brown, 20-30 µm high. Asci (4-)8-spored, broadly clavate to ellipsoid, bitunicate, the apical thickening with an internal beak, K/I-. Ascospores 1-septate, slightly constricted at septum, with slightly unequal cells, at first hyaline, finally pale brown, sole-shaped, (14-)18-22(-23) x (5.5-)7-9(-11) µm, when young bearing 2–3 flagella-like appendages which disappear with age. Photobiont absent (or thallus loosely associated with trentepohlioid algae). Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
