Description: Thallus endosubstratic to (rarely) thinly episubstratic and forming c. 30 µm wide specks, pale grey to brownish grey, sometimes separated from adjacent thalli by dark prothalline lines. Perithecia black, without involucrellum, immersed in pits in the rock, (0.3-)0.4-0.5(-0.7) mm across. Exciple dark throughout; hymenial gel I+ red (I+ blue at very low concentrations of iodine), K/I+ blue; hymenial algae isodiametric to shortly oblong, 2.5-5 x 2.5-3.5 μm, 1-2 times as long as wide; hamathecium of periphyses and periphysoids, interascal filaments absent. Asci 8-spored, clavate, the wall thickened above, with an ocular chamber, after dehiscence with a delicate extruded endotunica, I-, K/I-. Ascospores muriform, hyaline to yellow-brown at maturity, ellipsoid, (25-)30-40(-45) x (15-)18-25(-28) μm. Photobiont chlorococcoid, present in both thallus and hymenium.
