Spicil. Fl. Germ., 1: 109, 1794.
Synonyms: Amphoridium rupestre (Schrad.) A. Massal.
Description: Thallus crustose, endosubstratic, forming a grey-white to pale brown discoloration on the rock, without a distinct prothallus. Perithecia black, fully immersed in the rock or rarely very slightly projecting only with the up to 0.3 mm wide apical part, leaving pits in the rock when they fall off. Involucrellum black, up to 0.4 mm across, the upper part thick, becoming progressively thinner toward the base, usually encircling the exciple or reaching at least to mid-level; exciple c. 0.3 mm across, the wall dark in upper part, pale in lower part; hamathecium of periphyses and periphysoids, interascal filaments absent; hymenial gel 1+ blue turning reddish. 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, oblong-ellipsoid, 17-25 x 9-13 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
