Alectoria variegata (Samp.) Tav.

Syn.: Alectoria dichotoma var. variegata Samp., Alectoria ochroleuca var. variegata (Samp.) Zahlbr.
Lichenised. Poorly known taxon.
Substrate: acidic soil (mostly on siliceous substrata)
Altitudinal distribution: alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)
Note: a species of doubtful taxonomic value, differing from other Alectorias of the A. ochroleuca-group mainly in the conspicuous violet-black patches on the thallus surface; described from siliceous boulders in the montane belt in Portugal and hardly recorded from elsewhere, except one terricolous finding in the alpine belt of the Western Alps (France).
France: Haute-Alpes;
