description Usnea florida Overview

Usnea florida is a fruticose beard lichen that forms bushy, branching tufts on the bark and branches of trees. Like other members of Usnea, it has threadlike branches with a central elastic cord inside the outer algal layer, a structure that helps distinguish beard lichens from superficially similar mosses. Its presence is associated with long-lived woody surfaces and humid, relatively clean air, but species-level identification usually requires close examination.
