A composite organism consisting of a fungus and an alga or cyanobacterium living in symbiotic association. Lichens may be crustlike, scaly or leafy, or shrubby in form and are classified on the basis of the fungal partner. Many lichens are extremely sensitive to atmospheric pollution and have been used as pollution indicators.
