LICHALP

Arthopyrenia salicis A. Massal.

Syn.: Leiophloea salicis (A. Massal.) Trevis., Pyrenula salicis (A. Massal.) Trevis.

Non- or doubtfully 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 temperate coloniser of the smooth bark of deciduous trees and shrubs, especially Carpinus and Corylus, most frequent in upland areas. The species was probably mistaken for A. punctiformis and related species in the past.
