Substrate and Habitat. Corticolous on hardwoood trees, particularly on canopy branches.
Distribution. Eastern North America; in North Carolina found throughout.
Note. Usnea endochrysea is morphologically indistinguishable from the common and widespread U. strigosa, but can be distinguished by slightly smaller ascospores (compared with 9-10 x 5-6 μm in U. strigosa).
