Description: Thallus crustose, thinly episubstratic, white to grey, rarely brownish or inapparent, continuous to somewhat cracked. Perithecia black, sometimes grey-pruinose, (0.25-)0.3-0.7(-1) mm across, strongly projecting from the rock, not covered by thallus. Involucrellum well-developed, covering the upper third of the perithecium; exciple dark in upper part, colourless or pale brown in lower part; hamathecium of periphyses and periphysoids, interascal filaments absent; hymenial gel I+ red (I+ blue at very low concentrations of I), K/I+ blue. Asci 8-spored, narrowly ellipsoid to clavate, I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of a delicate rostrum. Ascospores 1-septate, hyaline, ellipsoid, (17-)21-32(-40) x (7.5-)10-14(-16.5) μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
