Lichen on a Log

I think that had I multiple lives to live, I would spend one of them studying lichen and moss. I love the patterns and colors of both these complicated living things. Lichen is a composite organism that arises from algae or cyanobacteria (or both) living among filaments of a fungus in a symbiotic relationship. See Wikipedia: Lichen. Lichen is not a plant. There are over 20,000 known species of lichen, but I suspect that there are many more yet to be classified or even discovered. I always notice the lichen. This log is in the Denali National Park in Alaska.
