Classification of Lichens: The systematic position of lichens is a controversial matter because it is a combination of two different members of two different groups. Polyphyletic, unrelated fungi that reproduce without a sexual cycle, are placed for convenience in a sixth group called a “form phylum.” Not all mycologists agree with this scheme. Lichens do not conform precisely to the usual biological classification categories as they are composed of two or more types of organism living within a single body. Lichens are slow growing, long living organism formed by the symbiotic association between algae and fungi that form a unique morphology distinct from both partner.
