Description: Thallus crustose, very thinly episubstratic, forming sparse, irregular, dark brown to almost black, poorly delimited flecks. Perithecia black, sparse, c. 0.3 mm across, half immersed, at first covered by a thin thalline layer, then the emerging part naked at least in upper half, hemispherical, smooth. Involucrellum thick, black, 0.4-0.5 m across, limited to the upper half of the perithecium, adpressed to exciple; exciple brown to brown-black in upper part, pale 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, clavate, I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of a delicate rostrum, 108-110 x 43-48 µm. Ascospores 1-septate, hyaline, ellipsoid, 38-45 x 14-18 μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
