I should make it clear that I'm not an expert on this subject. These photos include microcosms inhabited by other small beings - plants, mosses, liverworts, and so on; probably some of what I think are lichens are not. The great reference book on the subject is LICHENS OF NORTH AMERICA by Irwin M. Brodo, Sylvia Duran Sharnoff, and Stephen Sharnoff (Published by Yale University Press). It's expensive and heavy, but comprehensive and beautiful. That's the place to go if you really want to learn about these beings - but if you browse on this webpage you can accompany me on six months of lichen-stalking in Maine. I hope you receive from the expedition some of the enjoyment that I did.

These photos have been selected and set up to make it worth while to zoom in, increasing the magnification many times. Many of them get sharper and more fascinating as you do so. (See the Instructions on the home page if you're not sure about doing this.)
