Usnea is not a plant but rather a fruticose lichen combination of two kinds of organisms,
Fungus and alga, growing in a symbiotic union. Some Usnea species reproduce
by soredia, whereby a moldlike fungus captures and entraps microscopic green
algae, resulting in a new stable thallus of a specific structure with no resemblance
to its fungal or algal antecedents. Usnea has vague species limits with considerable
morphological variation within single populations, making species identification
difficult or even impossible. It grows on the bark and wood of coniferous
(e.g., Douglas fir and ponderosa pine) and deciduous hardwood (e.g., oak,
and apple and other fruit trees) host trees in orchards and damp forests throughout
the northern hemisphere in Asia, Europe, and North America (Hale and Cole,
1988; Hobbs, 1986; Kjeldsen, 1997).
