  • pH of the substrata: intermediate between very acid and subneutral (2) to subneutral (3)
  • in sun-exposed sites, but avoiding extreme solar irradiation (4) to sites with very high direct solar irradiation (5)
  • humidity requirements: mesophytic (3) to xerophytic (4)
  • in sites with no eutrophication (1) to sites with very weak eutrophication (2)
  • from the mediterranean-montane belt (3) to the oroboreal belt of the Alps (4)

    Note: on sunny basic siliceous rocks along seepage tracks. This taxon was synonymised by Hafellner & Türk (2001) with Cryptothele rhodosticta. However, for several reasons (see Nimis 1993: 589), I prefer to leave it here under Pyrenopsis waiting for surther studies on this very difficult complex
