Distribution:

Description: Thallus crustose, thinly episubstratic, finely rimose, smooth, dark brown. Perithecia at first completely immersed in thallus, later projecting with the black, slightly pruinose, convex apical part, forming 0.6-0.8 mm wide projections. Exciple dark throughout, c. 450 μm across; involucrellum present, thick, limited to the apical part and widely spreading from the ostiolar region; hymenial gel I+ red (I+ blue at very low concentrations of iodine), K/I+ blue; hymenial algae more or less isodiametric; hamathecium of periphyses and periphysoids, interascal filaments absent. Asci 8-spored, clavate, the wall thickened above, with an ocular chamber, after dehiscence with a delicate extruded endotunica, I-, K/I-. Ascospores muriform, long remaining hyaline, then pinkish orange, ellipsoid, 40-68 x 12-28 μm. Photobiont chlorococcoid, present in both thallus and hymenium). Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: on periodically inundated, compact calcareous rocks at mid- to moderately high elevations; so far only known from the Western Alps (France); to be looked for in the Italian Alps.
