Mycorrhizal fungi. Hyphae (white) of a fungi (phylum Basidiomycetes) growing on the roots (brown) of the strawberry tree (Arbutus unedo). Mycorrhizal roots take up nutrients more efficiently than uninfected roots,while the fungi obtain carbohydrates and possibly B-group vitamins from the tree. The type of symbiosis (mutualism) seen here is known as an endotrophic mycorrhiza; the fungal hyphae form a mantle around the tree roots and also penetrate into the soil. In endotrophic mycorrhiza the fungus lives mainly within the cells of the root cortex | |
