Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: this is a member of the L. albella-group, which includes species with a pruinose disc and an ecorticate apothecial margin. It is distinguished by the polysporous asci and the Pd+ yellow apothecial margin (psoromic acid), and has a mainly northern distribution in Europe, growing on bark in rather shaded and humid situations
