  • pH of the substrata: very acid (1) to intermediate between very acid and subneutral (2)
  • in sites with diffuse light but scarce direct solar irradiation (3)
  • humidity requirements: rather hygrophytic (2)
  • in sites with no eutrophication (1)
  • from the oroboreal belt of the Alps (4) to the vegetation above treeline (5)

    Note: an arctic-alpine, probably circumpolar lichen, found on acid soil rich in humus and over bryophytes in fissures of siliceous rocks in cold, perennially humid situations, restricted to the Alps in Italy.
