Bagliettoa sp.
I can't find a colloquial name for this pinkish lichen from Bagliettoa genus - the genus itself does not seem as a very popular one on Internet and it was very difficult to ID... Lichen produces pinkish plaques of various sizes - I've found anything between 10 and 60cm in diameter or length on these cemetery slabs (and historic and protected monuments). It also sports black roundish perithecia, about 2mm in diameter, deeply embedded in thallus.
Found growing ina broad sunlight on many slabs in an ancient necropolis (the site is historic value and is protected by UNESCO), on slopes of mountains in Dubrovnik hinterland, near the tripartite border between Croatia, Bosnia and Montenegro. The climate is Mediterranean, hot and dry in summer, and the vegetation Mediterranean maquis and pine forest.
I thought of two look-alike species, B. cazzae and B. marmorea, both producing pinkish thallus - but I believe this would be the later because growing in plein sunlight (please see second reference).
