LICHALP

Caloplaca concinerascens (Nyl.) H. Olivier

Syn.: Lecanora concinerascens Nyl.

Lichenised. Poorly known taxon.

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: this species (with a grey-brown epithecium reacting K+ weakly pale violet) belongs to the Pyrenodesmia-complex. It has been probably confused with C. conversa (with a brown epithecium reacting K+ purple), and its distribution is therefore poorly known. It was hitherto found on sun-exposed surfaces of weakly to strongly calciferous rocks in the French Southern Alps, the Mediterranean region and the warmest parts of the Massif Central.
