Description: Thallus crustose, endosubstratic or very thinly episubstratic, whitish to pale grey, often bearing macropycnidia only. Perithecia rather rare, black, 0.3-0.6 mm across, only the lower fourth immersed in the thallus, round to usually elliptical, flattened at the top. Involucrellum blackish brown, extending to the base of the perithecium, markedly larger than the exciple, the latter colourless to brownish; hamathecium of paraphysoids which are mostly simple, and only rarely branched and anastomosing, except when adjacent to exciple. Asci 8-spored, narrowly clavate, bitunicate-fissitunicate, shortly stalked at base, the apex thickened into a tholus, with a narrow ocular chamber, I-. Ascospores (3-)6-7-transversally septate (rarely with a single longitudinal septum), hyaline, fusiform, 20-27 x (3-)4-5(-6.5) μm, uniseriate to sub-biseriate in the asci, not restricted at septa. Macropycnidia 0.1-0.25 mm across, half-projecting, black, rounded and somewhat flattened, resembling perithecia; macroconidia subapically inserted on the conidiogenous cell, (3-)5-7(-8)-septate, cylindrical, (18.5-)22-26(-28) x 3.5-4.5 μm, rounded at apex and with a gelatinous appendage. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
