Description: Thallus crustose, episubstratic, pale grey-brown to medium brown, not gelatinous when wet, 60-480 μm thick, smooth, matt to slightly glossy, usually cracked. Cortex brownish, weakly developed; thallus cells not or only weakly arranged in columns; medulla without a black basal layer. Perithecia black, 0.2-0.4 mm across, immersed, the apex sometimes slightly projecting. Involucrellum absent or very poorly developed around the ostiole, not spreading; exciple brown throughout or colourless in lower part; hamathecium of periphysoids, interascal filaments absent; hymenial gel hemiamyloid, I+ red (I+ blue at very low concentrations of I), K/I+ blue. Asci 8-spored, clavate, I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, (23-)25-31(-36.5) x (10.5-)11.5-13(-14.5) μm, (1.9-)2.1-2.6(-3) times as long as wide, often with a 0.8-2.5 μm thick, gelatinous perispore. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
