Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: distinguished from A. lignicola by the narrower ascospores (< 3 µm); on wood, more rarely on siliceous rocks in forests; in the study area so far only reported from Switzerland.
