LICHALP

Protoparmelia olivascens (Nyl.) Llimona

Syn.: Lecanora olivascens Nyl.

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)

Note: a silicicolous species resembling P. montagnei, but with effigurate margins, and medulla reacting K+ yellow, then red; apparently more widespread in SW Europe, with a few records from the Western Alps (France).
