Lichenised.

Substrate: bark

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: a mild-temperate species found on the nutrient-rich bark of several trees (e.g. Acer, Fraxinus, Populus, Ulmus), in deep fissures of the bark seldom wetted by rain, with optimum at low elevations; recent records from the Alps are rare.
