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 of the C. crenulatella-lactea-group with a well-developed thallus consisting of yellow areoles becoming squamulose towards the margin; on limestone, mostly in at least seasonally dry habitats; in the study area so far only known from the Western Alps, in a xerothermic station.
