Witches' Hair (Alectoria sarmentosa)
forming a symbiotic relationship). It lacks central strands. It is high in fiber and contains nitrogen.
When parts of it fall to the ground, it mixes with the soil, enriching it. Its presence is an indicator of
little or no pollution in the environment.
Regarding its edibility, it contains usnic acid (an antibiotic), but it is not recommended to consume it
internally. Animals, such as deer and elk use it as a small component of their diets without any apparent
negative side effects. Externally, it can be used to dress wounds or in diapers because of its absorbent
and antibiotic properties. It can also be used as bedding in an emergency situation; when dry, it makes
good tinder.
Regarding whether or not this lichen harms the host tree, it looks like it doesn't. Many of these "fungi"
can be seen on sick trees--which, apparently where already sick before the "tenants" moved in.
Old man's beard (Usnea barbata) is a similar lichen, but has central, flexible strands.
