    Thallus crustose, endolithic, smooth to slightly rugose, well delimited, prothallus inconspicuous, pale pink-purple, matt, often minutely dotted with dull black, but sometimes faded. Perithecia usually numerous, 0.1-0.2 mm diam., uniformly scattered all over the thallus, immersed in minute wells, apices little protruding or flat hardly visible, involucrellum black with radiating ribs; after perithecia loss minute cavities remain. Mature ascospores unknown. Photobiont: green algae. Chemical spot tests negative. Not especially maritime, absent in our prospection region, on  humid and shaded or little-lit hard limestone rocks, mainly in Mediterranean region. See Bagliettoa marmorea of which the thallus is more bright pink-purple with numerous pycnidia, larger perithecia without involucrellum and mature ascospores, on well-lit calcareous rocks.
