Syn.: Verrucaria amylacea Hepp nom.illeg. non Ach.

Lichenised.

Substrate: siliceous rocks, calciferous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: on limestone and dolomite in sheltered situations protected from rain, e.g. with Caloplaca cirrochroa; perhaps regionally overlooked, and more widespread in the Alps.
