Altitudinal distribution: subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a species with a thallus consisting of olivaceous-grey granules and 3-septate ascospores (to 30 µm long), based on a calcicolous type from Canada (Ontario); the identity of the single European record from the Austrian Alps (on temporarily inundated schists in the subalpine belt!) needs confirmation.
