Pertusaria stenhammari Hellb.
Lichenised.
Substrate: bark
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: a very rarely collected, apparently panboreal-montane species found on the bark of conifers, with optimum in the upper montane and subalpine belts. Normally fertile, but the var. elatina Erichsen, described from the Alps, is sorediate.
Austria: Tirol; Italy: Trentino Alto Adige; Slovenia: Alpine and Pre-Alpine Slovenia;
