Magic,

Alectoria Sarmentosa or "Old Man's Beard" is a form of lichen and isalso known as "Witch's Hair". In the big woods its a favorite food source of whitetails and grows on evergreen trees. Up here you can see the "lichen browse line" up to where the deer can reach. I tend to find a lot of sheds under jack pines, where they fall off while the deer are eating lichen.
