Mycorrhizal fungi are mushrooms that work symbiotically with plant life, eg. our crops, by exchanging nutrients, carbohydrates, sugars, and water. Plants can benefit from this relationship by receiving moisture and nutrients trapped in the soil too deeply for the plants roots to access. The mushroom network, aka 'mycelium' acts as an extension of the root system by bringing these materials to the plants roots. The mushrooms, in exchange, receive the carbohydrates and sugars that support their own growth and health. These mycorrhizal associations improve soil microbiology, soil texture, and crop yields. They also enable plants to have a more secure source of water during drought-like conditions. Interested in more? Check out 'Paul Stamets', a mycologist, and http://mycorrhizas.info/
