Mycorrhizal Networks Dr. Simard writes: Mycorrhizal fungi form obligate symbioses with trees, where the tree supplies the fungus with carbohydrate energy in return for water and nutrients the fungal mycelia gather from the soil; mycorrhizal networks form when mycelia connect the roots of two or more plants of the same or different species.  …… Mycorrhizal networks may be critical in helping forest ecosystems deal with climate change.
