Description: Thallus crustose, continuous, endosubstratic, penetrating for up to c. 4 mm in the calcareous rock, pale greenish grey to pale pinkish grey, turning whitish in the herbarium, with macropycnidia only. Perithecia unknown. Macropycnidia 0.12-0.15 mm across, entirely immersed, pale except at apex, without involucrellum; macroconidia subapically inserted on the conidiogenous cell, (2-)3(-4)-septate, subcylindrical, with a gelatinous appendage, (10-)11.5-14.5(-16) x (2.5-)3-4.5(-5.5) µm; micropycnidia unknown. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a sterile, macropycnidiate, calcicolous species growing on sheltered calcareous rocks in the Mediterranean belt. Hitherto known only from southern France (Ardèche, Vaucluse) and Portugal (Algarve), but probably more widespread (Roux & al. 2004). To be looked for in Mediterranean Italy.
