is a fungi that has a beneficial relationship with a plants roots.
When Mycorrhizal fungi comes into contact with a plants roots it begins
to colonize, or multiply, on the roots and begins to spread out into
the surrounding soil. These strands of mycorrhizal fungi effectively
become an extension of the roots and can increase the absorbtion area
of a plants root system by 10 to 1,000 times. This allows the root
system a more efficient intake of nutrients and water.
