Description: Thallus crustose, episubstratic, grey-white to dark grey-green, thin, developing on the thalli of Baeomyces-species, immersed in the thallus of the host and appearing as a dark spot. Apothecia lecideine, black, 0.2-0.5 mm across, sessile, not constricted at base, with an initially urceolate, then concave to finally flat, smooth disc, and a thick, rugose, persistent proper margin. Exciple dark brownish green in the outer and innermost parts, paler inbetween; epithecium brownish to greenish brown, K-; hymenium colourless, inspersed with oil droplets, I ; paraphyses free, slender (to 2 μm thick), branched and anastomosing, not thickened at apex; hypothecium brown in lower part. Asci 8-spored, subcylindrical to clavate, the wall of young asci with a poorly developed tholus and an ocular chamber, that of mature asci more or less uniformly thick throughout. Ascospores (8-)12-15-septate, hyaline, acicular, thin-walled, (20-)30-70(-90) x 2-3.5(-4) μm. Pycnidia black, usually superficial, rarely immersed. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
