Mycorrhizal Fungi - More Photos

1.  95% of the root system of this plant is colonized with ectomychorrhizal fungi. Ectomychorrhizae are important for nutrient absorption by tree and grape roots. The fungus does not actually invade root cells, but forms a sheath that penetrates between plant cells. The shealth is this photo is white, but it may be black, orange, pink or yellow. Ectomycorrhizal fungi usually found on evergreen plants.
