Description: Thallus crustose, fully endolithic, usually covering large surfaces, white to pale grey, often delimited from adjacent thalli by a dark prothalline line. Upper cortex (lithocortex) densely prosoplectenchymatous, of conglutinated hyphae intermingled with microcrystals; algal layer discontinuous, photobiont cells in clusters; medulla prosoplectenchymatous, with oil cells (macrospheroids) in the lower part. Perithecia numerous, completely immersed in thallus and leaving pits in the rocks when they fall off. Involucrellum black, disc-shaped, with radial cracks around the ostiole, c. as large as or slightly larger than the excipulum (0.2-0.3 mm); excipulum dark throughout; hymenium colourless, K/I+ blue; hamathecium of periphyses in the ostiolar canal, and short periphysoids in the upper half of the perithecial cavity. Asci 8-spored, two-layered, fissitunicate, with a thin tholus reacting I-, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, often poorly developed, 13-26 x 7-15 µm. Photobiont chlorococcoid. Spot tests: all negative. Chemistry: without lichen substances.
Note: a mainly mild-temperate lichen found on compact limestone and in exposed situations, with optimum in the submediterranean belt; albeit rarely, it also occurs in disturbed habitats (e.g. on monuments in Rome).
