Syn.: Lecidea clavulifera Nyl., Micarea clavulifera (Nyl.) Coppins & P. James
Lichenised.
Substrate: siliceous rocks, acidic soil (mostly on siliceous substrata), 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: on acid siliceous stones and consolidated soil of dry underhangs, on banks or on the roots of fallen trees; perhaps overlooked and more widespread in the Alps, but certainly rare.
