A lichen is a mutualistic association between a fungus and a green algae or cyanobacteria. There are clear morphological differences in lichen body form; some have flat bodies and are very close together, others have leaf-like bodies, and still others grow upright. The association between the two organisms is so complete that lichens are classified as a single organism.
