| Descripción: | Picture taken at Garraf Park Information Center, on a brick wall, South exposure, vertical, 300 m. altitude. Common lichen on calcareous rocks and walls. Crustose lichen, very variable, areolate, thick, with a very typical white marginal area of the thallus and with not a very conspicuous dark prothallus.Apothecia present, with a black disc, with pruina , 1 mm diameter. It is very variable. It is necessary to compare with existing Rinodina species, very similar in form. I remind you a very good paper on Rinodina with keys: M. Giralt, X. Llimona (1997) The saxicolous species of the genera Rinodina and Rinodiella lacking spot test reactions in the Iberian Peninsula. Mycotaxon, Vol. LXII, pp. 175-224.
