Distribution: N - TAA (Nascimbene & al. 2022).
Description: Thallus crustose, endosubstratic or thinly episubstratic, continuous to irregularly rimose around the perithecia, whitish grey. Perithecia black, 0.4-0.5 mm across, 1/2-1/3 immersed and leaving pits in the rock, with a distinctly flattened apex. Involucrellum rather thick, limited to the region around the ostiole; exciple brown in upper part, colourless in lower part; hamathecium of 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, K/I-, fissitunicate, the wall thickened above, with a broad ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum. Ascospores muriform, hyaline, ellipsoid, pointed at one end, 30-42 x 14-20 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
