Altitudinal distribution: subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a peculiar species with brownish grey, cushion-like, dense, radially arranged podetia arising from a crustose basal thallus, apical ascomata with a black, epruinose mazaedium, and 1-septate ascospores with a helicoid perispore; on the top of not too tall spruce trees often visited by birds; widespread in the Holarctic region, with a single record from the Eastern Alps (Austria).
