Usnea species, Old Man's Beard, Beard Lichen, Treemoss.

Usnea species (species of lichen in the family Parmeliaceae, that generally grow hanging from tree branches) prefer specific chemical and physical qualities and choose to grow on certain tree species. One of the main factors, affecting their occurrence is the acidity of bark, which varies according to tree species; for example, Betula pendula has normally acid (pH 3.4–4.0).
