Lichens
Lichens are comprised of an alga and a fungus growing together in a close, mutually beneficial or symbiotic relationship. Lichens rely on the photosynthesizing alga to provide fixed energy and the fungus to provide moisture and mineral nutrients that it absorbs from the surrounding environment. Because lichens have no roots and depend upon stable surfaces to grow, we often find them on the bark of trees and on rocks. We don't know how many lichen species there are in the world; however, California catalogs 1575 lichens. Many of these are threatened by air pollution.
