Description: Thallus crustose, episubstratic, pale grey-brown to pale brown, 0.15-0.23(-0.3) mm thick, not gelatinous when wet, irregularly cracked-areolate, delimited by a discontinuous, black prothallus, the fertile areoles 3-4 times taller and wider than the sterile ones. Cortex 20-30 μm thick; algal layer c. 100 μm thick, continuous, the cells arranged in more or less distinct columns; medulla whitish, c. 100 μm thick, paraplectenchymatous, in lower part often patchily brownish, especially around the perithecia. Perithecia black, immersed in the centre of areoles, 1(-3) per areole. Involucrellum adpressed and completely surrounding the exciple, 50-70(-80) μm thick; exciple 0.2-0.25 μm across, the wall dark brown throughout; hamathecium of up to 40 μm long periphyses and periphysoids, interascal filaments absent. 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 x 8-10(-12) μm. Pycnidia black, completely immersed in thallus, 100-150 μm across. Conidia oblong, 6-8 μm long. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
