Makes an excellent dye for wool but its not as common in my immediate area so usually only harvest from the ground. I was happy to see this big doug loaded with it.

While this lichen doesn't fluoresce under UV, a little section did light up. I have wondered if it isn't another lichenicolous fungi colonising the Letharia.
