Protoparmelia placentiformis (J. Steiner) Poelt

Syn.: Lecanora placentiformis J. Steiner
Lichenised.
Substrate: siliceous rocks
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: on sunny siliceous rock in dry areas; described from arid parts of Asia, after the record from Macedonia, the record from the Ligurian Alps is the second one from Europe. This characteristic lichen probably does not belong to Protoparmelia s.str.
