Recognized by sight: same color as Alectoria, but Usnea has a “rubber band” in the center of its branches — pull on a branch until it snaps in two, if it breaks cleanly it’s Alectoria or Bryoria, if a stretchy central cord is revealed which breaks last after the rest of the branch has already split then it’s Usnea.

Had a ball snapping these yesterday (Friday). Didn’t expect that.
