Description: Thallus crustose, episubstratic, not subgelatinous when wet, continuous to usually strongly rimose or cracked-areolate, (35-)50-120 μm thick, grey-green or pale to dark brown, smooth, matt to slightly glossy, up to several cm wide. Cortex poorly developed, paraplectenchymatous, with or without a brown pigment; medulla very thin, inconspicuous, without a black basal layer. Perithecia forming 0.2-0.5 mm wide, low to rather distinct projections, covered by a thalline layer on the flanks, with the black, naked, convex apex exposed, the ostiolar region visible as a pale, 20-110 μm wide, flat or depressed spot. Involucrellum limited to the apex or well-developed and spreading outwards and downwards almost to base-level; cell lumina in lower part of involucrellum not much enlarged, completely carbonised or with dotted pigmentation; exciple subglobose, 0.14–0.22 mm across, the wall c. 20 µm thick, colourless or patchily pale brown in lower part; hamathecium of c. 20 µm long periphyses and 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, (21.5-)24-29(-35) x (8.5-)10.5-12.5(-14.5) μm, with a thin perispore. Photobiont chlorococcoid, the cells irregularly dispersed (not arranged in columns). Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
