Violella fucata (Stirt.) T. Sprib.

Sorediate, mostly sterile, on acidic bark of various trees. Abundant on beech trunks in older managed and old-growth forests. It also grows on bark of coniferous trees, typically on branches, both living and dry. Common on wood – snags or well-lit lying logs. Abundant in montane and submontane areas in the Czech Republic, disappearing towards lowlands. Similar climatic preferences are observed throughout the continent – it grows mainly in northern Europe or in mountains. Easily identified based on amorphous black fruiting bodies of basidiomycetous Tremella lichenicola, a commonly associated parasite or parasymbiont.
