Parmelina tiliacea
It is a very common lichen, with big grey leafy-like tallus. Often on the bark of pine trees, oak trees and even on mossy rocks as in the present case. Easy to recognize by its light-grey color and big marginal lobes. The presence of dark brown isidia covering the surface of the tallus help to confirm the identification. Apothecia are rare in this species.
Spotted on top of a mossy granite rock. Reserva de la Biosfera del Real Sitio de San Ildefonso-El Espinar.
