Wolf Lichen
Letharia vulpina
Lichenes

Wolf Lichen is usually associated with the northwestern part of the country. However, it is known that with the shipping and transfer of conifers to the southern states the lichen spores are apt to be shipped and transferred as well. The good part is that this invasive parasite does not enjoy long life in our semi-tropical environment, and rarely spreads from one dead tree to another.

To identify Wolf Lichen, look for mossy masses that are yellow to chartreuse in color, hanging from the branch in long tag-like clusters 4 to- 6 inches long. The tufts are irregular in size and length, and have a powdery texture. Its preferred habitat is on the trunks and branches of dead or dying pine, fir, spruce and cedar trees.
