In today’s steady rain, a couple of miles up Buffalo Bill Creek, the only “sunshine” I saw was this brightly colored lichen. Its yellow color is derived from two poisonous substances, pinastric and vulpinic acids which occur only in lichens and are thought to deter grazing by insects and other invertebrates. Pretty, isn’t it!
I’m afraid that I know very little about lichens, but there are sure a lot of them around here. Perhaps I should start learning. I brought back more photos of some other and I will post them soon for anyone interested.
Every time you post a lichen or fungus, I think I should look around and see if we have some. I know there are a few that attach to some of the trees. I need to look more closely – mushrooms sort of pop up and demand attention, but lichens seem more quiet and retiring.
