LICHALP

Pyrenopsis picina (Nyl.) Forssell

Syn.: Synalissa picina Nyl.

Lichenised. Poorly known taxon.

Substrate: siliceous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: a species close to P. grumulifera from which it is often not distinguished, but with an effuse, thin, black thallus overgrowing mosses; overall distribution poorly documented, with a few records from the Western Alps (France).
