Lichen


In this picture is a piece of rotting wood with lichen on it. Lichen is an organism that usually is made up of a fungus that grows symbiotically with algae or some cyanobacterium. Lichen usually takes up a crust-like or branching form on rocks or tree trunks. In the case of the lichen above, it seems to be a little more crust-like.
