A lichen is a composite organism that arises from algae or cyanobacteria (or both) living among filaments of a fungus in a symbiotic relationship. The combined life form has properties that are very different from the properties of its component organisms.Lichens come in many colors, sizes, and forms.yanobacteria photobionts are called cyanobionts.
