Catillaria atomarioides (Müll. Arg.) H. Kilias

Syn.: Catillaria lenticularis (Ach.) Th. Fr. var. atomarioides (Müll. Arg.) Erichsen, Catillaria microcarpa R. Sant., Lecidea atomarioides Müll. Arg.
Lichenised.
Substrate: siliceous rocks
Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: an inconspicuous lichen found on steeply inclined surfaces of hard siliceous rocks in humid situations, mostly in upland areas; very much overlooked and certainly more widespread in the Alps.
