Mycorrhizae are mutualistic relationships between soil fungi and plants.
Because mycorrhizae colonize the area around plant roots, they are found mostly in soil.
The fungi involved typically belong to the phyla Glomeromycota or are sac fungi.
Because mycorrhizae are a part of a mutualistic relationship, plantsare benefitted by increased mineral uptake while fungi are benefitted by receiving carbohydrates from plants.
