Description: Thallus crustose, ecorticate, endosubstratic to (very rarely) thinly episubstratic, smooth to rarely finely rimose, effuse, pale grey to brownish grey, often with a pinkish tinge when fresh. Perithecia black, 0.5-1.2 mm across, one quarter- to half-immersed, conical-hemispherical, often flattened and with distinct papillose ostioles. Involucrellum dimidiate, spreading outwards from the exciple; exciple colourless; hymenial gel I-, K/I-; pseudoparaphyses persistent, slender, sparingly branched or anastomosing, long-celled; periphyses absent. Asci 8-spored, narrowly cylindrical, K/I-, fissitunicate, the apical dome with a broad ocular chamber surmounted by a hemispherical meniscus-like structure. Ascospores 1-septate, not or slightly constricted at septum. the septum thick and the cells equal, hyaline, ellipsoid with rounded or rarely pointed ends, 12-19 x 6-9 μm, uniseriately arranged in the asci, surrounded by a perispore which appears verrucose in water, smooth in K. Pycnidia frequent and often numerous, black, 0.1-0.2 mm in diam. Conidia acrogenous, ellipsoid, simple, colourless, c. 3-3.5 x 1.5 μm. Photobiont trentepohlioid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a mild-temperate species of compact limestone and dolomite, mostly in woodlands, on sheltered faces seldom wetted by rain, with optimum in submediterranean areas, but reaching near treeline in the Apennines. The forma carnea Arnold, with pale perithecia, has been reported from the Julian Pre-Alps (Tretiach 2015).
