Description: Thallus foliose-umbilicate, monophyllous or of a few connected lobes, rather thin (0.2-0.5 mm thick when dry), attached by one or rarely a few central holdfasts. Lobes usually concave (5-)7-18(-25) mm wide. Upper surface grey to almost black in parts, epruinose or only partially pruinose; lower surface smooth to partly verrucose. Upper cortex (40-)50- 90(-110) μm thick, brown in the uppermost part, with an epinecral layer of air-filled hyphae; medulla consisting of c. 3 μm thick hyphae; lower cortex (30-)40-60(-70) μm thick, the outermost part brown, consisting of 5-8 cell layers; crystals visible in polarized light and soluble in K present in the lower cortex. Perithecia dark brown to black, immersed, with a slightly protruding ostiole, more or less spherical, without involucrellum, the wall colourless except in the brown uppermost part. Hamathecium or periphyses and periphysoids, interascal filaments absent; hymenial gel hemiamyloid. 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, with more or less uniseriately arranged ascospores. Ascospores 1-celled, hyaline, narrowly ellipsoid, 7-10.5(-11.5) x 4.5-6(-6.5) µm. Pycnidia very rare, black. Conidia 5-6 x c. 1 μm. Photobiont chlorococcoid. Spot tests: cortex and and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
