Palicella filamentosa (Stirt.) Rodr. Flakus & Printzen

A crustose lichen, typically growing on death twigs of pines or spruces (usually on wood). However, it has a broader ecological amplitude and occurs also directly on bark of live trees, snags and worked timber, such as fences. It is a typical mountain-boreal element. In the Czech Republic, it is one of the relatively common species, for example, in mountain spruce forests, raised bogs or boggy pine forests. Palicella filamentosa is nearly absent at lower elevations, at middle elevations it is found rarely and locally. The lichen is more common for example in the Třeboň basin. It is a relatively toxitolerant acidophile and occurs epiphytically even in places where the effect of pollution by sulphur dioxide is still apparent and where Lecanora conizaeoides still dominates, e.g. on dead trees in the Jizerské hory Mts. The species if quite morphologically variable and its light forms may be mistaken for the similar Lecanora symmicta.
