Lecanactis abietina (Ach.) Körb.

Lecanactis abietina produces typical conspicuous white pycnidia, containing gyrophoric acid (C+ red reaction). In the Czech Republic, the lichen is characteristic for mountain and boggy spruce forests, where it usually grows on spruce trunks or snags. It prefers old-growth natural forests but, in their vicinity, it may spread also into managed forests. In rather humid areas, the species may occur even in beech-fir forests directly on firs or beeches. In Europe, L. abietina is a boreal-montane element. In the Czech Republic, it is currently more abundant only in the Šumava Mts. The species was probably more common also in other higher mountains in the past, but has declined in consequence of acid rain.
