Icmadophila ericetorum (L.) Zahlbr.

A boreal-montane lichen that inhabits a relatively wide substrate spectrum. Most often, it is found on a wet wood in a late stage of decomposition. It commonly grows also on acidic soil, peat or directly on partly shaded siliceous rocks and stones. The species prefers rather relict and humid habitats, such as screes, rocky ravines in sandstone areas, peat bogs, boggy forests and humid mountain forests. In the Czech Republic, it occurs mainly in mountains. Its occurrence at lower elevations is linked to deep, cold valleys and ravines. The lichen is rare in the country. Higher abundances are known only from the Šumava Mts, Krkonoše Mts and north-Bohemian sandstone areas. Within Europe and the Northern Hemisphere, Icmadophila ericetorum is a widespread but only locally common species.
