Morphology
Usnea + barbata
Although 'barbata' is not listed in the provided dictionary, it is a Latin adjective meaning 'bearded' or 'hairy' and 'Usnea' names a genus of hanging lichens. As a compositional binomial (genus + descriptive adjective) the phrase literally describes a 'bearded' Usnea with long hanging strands, so a B1 learner who knows both constituents could infer the meaning.
Etymology
Usnea barbata comes from old Latin words: Usnea named a kind of lichen and barbata means 'bearded'. The name gives a clear image of long, green strands like a beard hanging from tree branches, so the name fits this lichen today.
