Ramonia calcicola  Canals & Gomez-Bolea Cf.

    Thallus crustose, epilithic, more or less uneven, sometimes slightly cracked, white-greenish, white-pinkish, eventually orange tinged owing to the photobiont. Apothecia immersed or slightly superficial, 0.2-0.3 mm diam., with aperture of the same size (Gyalecta-like), slightly indented, disc pinkish to pink-orange. Ascii clavate to cylindrical, 8-spored, 90-100 x 12-16 µm. Ascospores fusiform, perispore gelatinous, 3-5(7)-septate, 18-23 x 4-6 µm. Photobiont: Trentepohlia. C-, K-, KC-, Pd-. Rare, on shaded and humid vertical walls of calcareous rocks. Differs from Petractis luetkemuelleri by its habitat, soft, humid calcareous rocks, its thallus rough to granulose without visible pink tinge, its numerous apothecia hardly visible, and by its ascospores,  3-5-septate.

N.B. Probably here a lusus of Petractis luetkemuelleri
