Caloplaca subpallida H. Magn.
Syn.: Caloplaca oxfordensis auct. non Fink ex J. Hedrick, Rufoplaca subpallida (H. Magn.) Arup, Søchting & Frödén
Lichenised. Poorly known taxon.
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 cool-temperate to arctic-alpine lichen found on mineral-rich siliceous rocks, sometimes parasitic on other lichens (Aspicilia, Rhizocarpon, Xanthoparmelia). The species has been often considered as a synonym of C. oxfordensis J. Hedrick, a taxon described from North America, but molecular data indicate that the two species are different.
