Bacidia viridifarinosa Coppins & P. James

Lichenised.

Substrate: siliceous rocks, bark

Altitudinal distribution: submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)

Note: a suboceanic species growing on shaded, smooth and not too acid siliceous rocks in oceanic humid woodlands, sometimes on smooth bark at the base of old deciduous trees; mostly sterile, with confluent soralia giving raise to yellow-green farinose soredia; the type material is from an old Tilia tree; it is not a Bacidia and belongs in the Pilocarpaceae; from the Alps there are only a few scattered records.
