Protoparmeliopsis graeca (J. Steiner) Sipman & Cl. Roux
Syn.: Lecanora graeca J. Steiner
Lichenised. Poorly known taxon.
Substrate: calciferous rocks, intermediate rocks (such as calciferous schists)
Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: hitherto known only from the eastern Mediterranean, the Maritime Alps of France, and the Central Apennines, this lichen occurring on base-rich or slightly calciferous siliceous rocks is worthy of further study.
