Evernia prunastri

Epiphytic lichenised fungus with strong preference for acidic-barked broadleaves; extremely common on mature oak.

Also abundant on ash bark, particularly in moist western woodlands.

Commonly colonises rowan bark in upland and montane woodland.

Golden Oriole incorporates oakmoss lichen as key camouflage and structural material in its suspended nest.
