Lichen | Definition, Symbiotic Relationship, Mutualism, Types . . . lichen, any of about 15,000 species of plantlike organisms that consist of a symbiotic association of algae (usually green) or cyanobacteria and fungi (mostly ascomycetes and basidiomycetes) Lichens are found worldwide and occur in a variety of environmental conditions
