Methusalah's Beard
The beard's scientific name is Usnea longissima. A tuft of hanging sort of hair. Methusalah's is a lichen, 15-35 cm long. It is found on trees and shrubs. This particular strand of lichen is found in the pacific northwest. Apparently it is really sensitive to air pollution, and is beginning to vanish. Because of this it is slow to grow, and should never be picked. I feel bad now.
