Caloplaca (sensu Arup et al. 2013)

8 species recognized in the region. Caloplaca in a modern sense ( Arup et al. 2013) is morphologically circumscribed by almost lecanorine apothecia and crustose thallus, formed by thin continuous crust or areoles, rarely tiny squamules. Apothecia are present in all species, vegetative diaspores are present (in 5 recorded species) or absent. Literature: Arup et al. (2013), Šoun et al. (2011), Vondrák et al. (2008).

Caloplaca cerina s.lat.: 27 localities at altitudes 140–1550 m, in humid and occasionally arid non-alpine habitats. Substrate: very common on trunks and twigs of Populus tremula , also on Betula , Juniperus , Larix , Pinus sylvestris , Populus laurifolia , Salix and Sorbus ; one epilithic record (Vondrák 10405) on dust-impregnated sunny schist. Šoun et al. (2011) demonstrated that the morphologically circumscribed C. cerina is not monophyletic in the ITS tree and more phylogenetic species are presumed to exist within it. We consider the population common on Populus throughout Altai-Sayan region to be a single species, but the population which is common on Pinus sylvestris in Tyva may belong to a separate species. Specimens from P. sylvestris (Frolov 1805, Vondrák 18262, 18410) have distinctly darker, red apothecia and dark grey thallus resembling the Mediterranean C. haematites .

Caloplaca chlorina : 4 localities at altitudes 250–1450 m, in humid and arid non-alpine habitats. Substrate: siliceous and calcareous rocks, usually in damp and +/- shaded places.
