LICHALP

Physcia dimidiata (Arnold) Nyl. var. ornata (Nádv.) Moberg

Syn.: Physcia dimidiata (Arnold) Nyl. f. ornata Nádv.

Lichenised.

Substrate: calciferous 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 variety with narrow lobes and crenate tips; usually on rocks with high content of calcium, often under overhangs; apparently this is the most common variety in Eastern and Central Europe, but it was not generally distinguished, so that the distribution in the Alps is insufficiently known.
