Syn.: Physcia pusilla Mereschk., Physcia pusilloides Zahlbr., Physcia suzai Nádv.
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 species found on isolated deciduous trees with nutrient-rich bark, especially Juglans and Fraxinus in montane valleys, absent from urban areas, somehow less frequent in semi-natural stands; often confused, in the past, with other species.
