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: the brown, persistent involucrellum reacting K+ green, as well as the strongly branched interascal filaments are diagnostic; usually on smooth bark in woodlands with a long ecological continuity; the total distribution is incompletely known.
