Letharia columbiana
The brown eyes are the fruiting bodies where spores are made for reproduction.
Spotted on the forest floor. The lichen underneath that it is attached to is Platismatia glauca (ragbag lichen).
Letharia columbiana, a wolf lichen, is used by Native Americans in California as arrow poison (sometimes mixed with snake venom), abd the Okanagan-Colville Indians have used it as an external medicine for sores, or an internal medicine for stomach disorders. The most common use of Letharia is as a source for bright yellow boiling water dye (Brodo et al. 2001).
