Note: "All our specimens of Ramalina webbii, as here delimited, came from a single locality in Fuerteventura, where they grew on a vertical rock face below 500 m altitude, together with Ramalina decipiens. On the basis of this rather limited material, in cannot be entirely ruled out that tha species merges with Ramalina crispatula and should be regarded as conspecific with it, but until more material of Ramalina webbii becomes available, we choose to treat them as separate species (Krog & Østhagen 1980: 293).
Ecology: Saxicolous.
Locality: Jandia, the northern part of Cuchillo del Cervo, 400 - 460 m, Krog & Osthagen 1299, 1301.
