Description: Thallus crustose, episubstratic, subgelatinous when wet, dark brown to black, consisting of 0.02-0.1 mm wide, granular goniocysts, often visible only around the perithecia. Perithecia black, 0.35-0.5(-0.8) mm across, immersed, with only the apex projecting, rarely partly exposed. Involucrellum absent; exciple 35-60 μm thick, brown throughout but paler in innermost part, sometimes forming a short neck in upper part; hamathecium of slender, 75-95 μm long and 1-1.5 μm wide pseudoparaphyses below the ostiole, interascal filaments absent; hymenial gel hemiamyloid, I+ red (+ blue at very low concentrations of I), K/I+ blue. Asci (3–)4–8-spored, ellipsoid to clavate, K/I-, fissitunicate, the wall thickened above when young. Ascospores muriform, brown to dark brown, opaque when mature, ellipsoid to broadly epllipsoid, 70-90(-160) x 33-50(-92) μm, larger in the asci with less than 8 spores. Photobiont chlorococcoid, but verrucose cephalodia with Nostoc frequent. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
