Placopsis lambii Hertel & V. Wirth

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: a species resembling juvenile thalli of P. gelida without cephalodia, usually sorediate, rarely with apothecia and normally poorly developed; ecologically similar to Lecanora subaurea, found on low outcrops and small boulders of metal-rich siliceous rocks in sites with an oceanic climate; in the study area known from a few localities, all below treeline in the Eastern Alps (Austria).
