White threads of fungal mycelium are sometimes visible underneath leaf litter in a forest floor. A mycorrhizal network (also known as a common mycorrhizal network or CMN ) is an underground network found in forests and other plant communities, created by the hyphae of mycorrhizal fungi joining with plant roots.
Suzanne Simard (born 1960) [3] is a Canadian scientist and Professor in the Department of Forest and Conservation Sciences at the University of British Columbia. [4] After growing up in the Monashee Mountains, British Columbia, [3] [5] [6] she received her PhD in Forest Sciences at Oregon State University. [4]
This experiment showed that through fungal mycelia linkage of the roots of two plants, plants are able to communicate with one another and transfer nutrients as well as other resources through below ground root networks. [55] Further studies go on to argue that this underground “tree talk” is crucial in the adaptation of forest ecosystems.
A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules by photosynthesis and supplies them to the fungus in the form of sugars or lipids, while the fungus supplies the plant with water and mineral nutrients, such as phosphorus, taken from the soil.
Ectomycorrhizal symbiosis, showing root tips with fungal mycelium from the genus Amanita. An ectomycorrhiza (from Greek ἐκτός ektos, "outside", μύκης mykes, "fungus", and ῥίζα rhiza, "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species.

The hyphal network of arbuscular mycorrhizal fungi (AMF) extends beyond the depletion zone (grey), accessing a greater area of soil for phosphate uptake. A mycorrhizal-phosphate depletion zone will also eventually form around AM hyphae (purple).
The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
