Lichen

These photos probably won't be as popular as birds and flowers, but I love all the colorful varied lichens you find on the rocks on the prairies. Lichens are symbiotic organisms consisting of algae or cyanobacteria (or both) living among filaments of a fungus. Most of these ones on the rocks are "cructose" or crusty lichens. On a positive note, healthy lichens are a sign of good air quality!
