A distinctive epiphytic lichen of boreal natural humid mountain coniferous and mixed forests (waterlogged climax spruce forest, Pinus rotundata boggy forests, beech-fir forests etc.). It grows mainly on bark of conifers (spruce, fir), less often on birches, beeches and other trees. A comparison of historical and recent data indicates its radical decline in the Czech Republic. Nowadays, the species is relatively common only in the Šumava Mts and the Novohradské hory Mts. However, even in the mentioned areas, its occurrence is restricted to old-growth, microclimatically stable forests. In the northern and eastern part of the country, the lichen probably disappeared.taxonomic classification: most frequented synonyms:Arthonia leucopellaea
