Description: Thallus crustose, endosubstratic, greenish white, smooth to slightly farinose, with gloeohyphae. Perithecia black, 0.2-0.3 mm across (in section), almost completely immersed in pits of the rock, slightly projecting with the apical part, globose, with a flattened ostiolar region. Involucrellum absent; exciple brown-black throughout; hamathecium of periphyses and slender, branched periphysoids; interascal filaments absent; hymenial gel I+ red, K/I+ blue. Asci 8-spored, ellipsoid to clavate, K/I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum. Ascospores 5-7-septate, sometimes submuriform with an incomplete longitudinal septum, hyaline, narrowly ellipsoid, 42-56 x 11-18 μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: on calcareous rocks in Eastern and Central Europe, with a few records from the Eastern Alps (Austria), mainly in the montane belt; to be looked for in the Italian Alps.
