LICHALP

Aspicilia viridescens (A. Massal.) Hue

Syn.: Pachyospora viridescens A. Massal.

Lichenised.

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: this species was often confused with A. contorta, but it occurs on siliceous rocks; it is rather common at low altitudes in the Western Alps.
