Lovely Lichen

It was cold and windy today (and not particularly spring-like), and all of the creatures I saw on my walk this afternoon stayed too far away for pictures. Lichen, however, doesn't move, and once I started noticing it on the trees, I saw it everywhere, and in so many colors and patterns! Here's my favorite lichen-y sight of the day, like someone splashed generous amounts of neon paint on this tree:
 

It occurred to me to try to identify some of these lichens (it looks like there are at least three different species here), but as it turns out, there are a lot of lichens in our area, and no clear identification resources (that I can find) online. Maybe someday I'll learn to identify lichens, but I'll just have to settle for the much simpler process of admiration for now. :)
