Lichen is a simple slow growing plant. Characteristically, it forms a low crust-like, leaf-like, branching growth typically on rocks, walls and trees . They are composite plants comprising a fungus that has photosynthetic algal cells. Lichens get their supply of water and nutrients from the atmosphere and they may be sensitive indicators of atmospheric pollution.Lichen is an ecologically obligate, stable mutualism between an exhabitant fungal partner and an inhabitant population of unicellular or filamentous algal or cyanobacterial cells. Lichen plays an important role in soil formation. They impart their grey, yellow or green color to the surface they cover.
The fungal partner of lichens is usually an ascomycete (sometimes a basidiomycete), the algal partner being a green (chlorophyta) or a blue-green (cyanophyta) alga. About 19% of all fungi and 42% of all ascomycota are lichenized. The number of photosynthetic partners involved in lichen formation is relatively small; out of 40 genera involved, 25 are algae and 15 are cyanobacteria.
