Lecanora cenisia morph. à thalle gris-bleu.

    This morph differs from the type by its relatively thick crustose thallus, pale blue-green, pale blue, bluish grey, bordered by a bluish grey prothallus (or pink in areas subject to seawater splashes) and its apothecia with a reddish, red-brown disc, at first very small and immersed in the thallus then emerging from the thallus and at the end sessile with a brownish to blackish-brown disc. This morphotype is rare and localized on sheltered siliceous rocks rich in iron at the seaside.

N.B. Interpretation according to the British authors, the French authors consider that this species is mountainous.
