Description: Thallus crustose, episubstratic, continuous to usually cracked, pale to dark brown, somewhat shiny, smooth, sometimes delimited by a whitish prothallus. Perithecia black, 0.2-0.3 mm across, immersed in (0.2-)0.3-0.6(-0.6) mm wide, conical-hemispherical projections with a brown to black apex, half to almost completely covered by a thalline layer. Involucrellum adpressed to exciple or slightly divergent in lower part, most often apical, rarely extending to the base of the perithecium; hymenial gel I+ red (I+ blue at very low concentrations of iodine), K/I+ blue; hymenial algae subglobose to oblong-ellipsoid, 1-1.5 times as long as wide, 2-4(-5) μm; hamathecium of periphyses and periphysoids, interascal filaments absent. Asci 2-spored, clavate, the wall thickened above, with an ocular chamber, after dehiscence with a delicate extruded endotunica, I-, K/I-. Ascospores muriform, pale to dark brown, oblong-ellipsoid to narrowly oblong, (30-)37-50(-60) x 13-25(-30) μm. Pycnidia black, frequent, Dermatocarpon-type. Conidia bacilliform, straight or slightly curved, 3-4 x c. 1.2 μm. Photobiont chlorococcoid, present in both thallus and hymenium. Spot tests: K-, C-, KC-, P-, UV-.
