Boreal Oakmoss - Evernia mesomorpha

This is a fruticose (shrublike) lichen, though its thicker branches remind me a bit of antlers. (Beard lichens and reindeer lichens have thinner branches.) Boreal oakmoss is a pale yellowish green, and the branches are pliable, not brittle. Branches are wrinkled and irregular, more so if tiny reproductive structures called soredia are present.
