LICHALP

Rinodina luridata (Körb.) H. Mayrhofer, Scheid. & Sheard subsp. immersa (H. Mayrhofer & Cl. Roux) Cl. Roux

Syn.: Rinodina iodes H. Mayrhofer & Poelt var. immersa H. Mayrhofer & Cl. Roux

Lichenised.

Substrate: calciferous rocks

Altitudinal distribution: submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)

Note: this taxon differs from the nominal subspecies in the endolithic thallus and the ecology (on hard, compact limestones, often with Bagliettoa marmorea); for the study area there are a few records from the Western Alps only (France), but the species could have not been distinguished elsewhere.
