Lichenised.

Substrate: bark, lignum

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: this species differs from L. symmicta, of which it is treated as a synonym by several authors, in the dark green to black apothecial discs and the early excluded apothecial margins; on twigs of Calluna and other shrubs, more rarely on lignum and bark of coniferous trees and oaks; most records from the Alps are ancient.
