i. Ectomycorrhizae:
In this association, the absorbing roots are almost completely enveloped by a mantle of very compact hyphae of the fungus. Plant like pines, willows, Picea, Cedrus, Betula develop their characteristic ectomycorrhizae.
The common fungal partners that enters the ectomycorrhuae are species of Cortinarius, Tricholoma, Amanita, Lactarius, Scleroderma. From the external mantle certain hyphae enter the cortex of roots and confine to the intracellular space of the cortical cells. The roots are stunted in growth, swollen due repeated dichotomy, become coral like and finally organised into condensed masses. The stellar portions and also the meristem at the apex are not inhabited by the fungus. Within the cortex of the root, the intercellular hyphae ramify extensively in the form of a reticulum to which the name 'Harting-net' is given (German botanist Hartigfound out this).
ii. Endomycorrhizae:
This kind of mycorrhizae is confined to the cells of the root system; causing internal infections of the cortex of root and rhizome of the plants.
The most important role of the fungus of endomycorrhizae is the disintegration of soil particles and absorption and transport of released particles in to the plants. The formation of endomycorrhizae does not alter the the morphology of the root system. The fungus is confined in the root cells and are grown externally root hairs are normally formed on the surface of the roots.

Endomycorrhizal Fungi form exchange mechanisms on the inside of the root cells, intracellularly (and the hyphae extend outside the root). Endomycorrhizal fungi form mostly with green leafy plants and most commercially produced plants. Examples: Most Vegetables, Grasses, Flowers, Shrubs, Fruit Trees, and Ornamentals. Approximately 85% of terrestrial plant species on Earth are endomycorrhizal.
Ectomycorrhizal Fungi form exchange mechanisms outside of the root cells, extracellularly. Ectomycorrhizal fungi form mainly with Conifers and Hardwoods, and are required mostly for woody plants/trees and forest trees. Approximately 10% of terrestrial plant species on Earth are ectomycorrhizal.
