Protoblastenia siebenhaariana (Körb.) J. Steiner subsp. albida Cl. Roux ined.

Syn.: Protoblastenia rupestris (Scop.) J. Steiner subsp. albida Asta & Cl. Roux [invalidly published, ICN Art. 40.1 + 8], Protoblastenia rupestris (Scop.) J. Steiner subsp. albida Cl. Roux, Protoblastenia siebenhaariana (Körb.) J. Steiner subsp. albida (Asta & Cl. Roux) Clauzade & Cl. Roux comb. inval.

Lichenised. Poorly known taxon.

Substrate: siliceous rocks, calciferous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: similar to var. siebenhaariana, but with a colourless hypothecium and a different ecology (mostly associated to Lecanora albula); the application of the name was often inconsistent, so that the distributional data (outside France) are hardly reliable.
