Distribution:

Description: Thallus squamulose, of contiguous to slightly overlapping, 3-7(-9) mm wide, flat to slightly convex, pale to medium brown squamules with down-turned margins, forming compact pillows. Lower surface black, without rhizohyphae, attached by 0.1-0.5 mm thick and to 15 mm long, branched and sometimes anastomosing, black rhizines. Upper cortex paraplectenchymatous, 40-100 µm thick, of 5-10(-13) µm wide cells, with a 10-25 µm thick epinecral layer; algal layer with vertically arranged photobiont cells; medulla white, prosoplectenchymatous, up to 100 µm thick; lower cortex absent. Perithecia black, pyriform, up to 0.6 mm across, immersed in the squamules, without involucrellum. Exciple up to 40 µm thick, with a pigmented outer layer and a colourless inner layer; periphyses 30-40 x 3-4 µm; interascal filaments absent. Asci 8-spored, oblong-clavate, the wall I-, with (sub-)biseriately arranged spores. Ascospores 1-celled, hyaline, ellipsoid, 14-18 x 7.5-9 µm. Pycnidia laminal, immersed in the squamules, Endocarpon-type. Conidia short-cylindrical, 4-6 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a species growing on calciferous soil, with a wide altitudinal range, described from Greece and also known from Cyprus and the Irano-Turanian region. To be looked for in Southern Italy.
