This article elaborates the mycorrhizal interactions, characterizes the types of mycorrhizal fungi and identifies the important points in the practical use of these fungi and shows information brought up to date on the subject. The techniques of modern Science formed the bases of the mycorrhizalogy that spread in world and today represents an important branch of Biological Sciences, with great possibilities for the commercial scanning, aiming to magnify the wood production, vegetable fibers and foods and to reduce the costs and the impact of modern systems of production on environment. The Brazil, due to its edafoclimatic conditions, agricultural, forestal and pastoral aptitudes and the scarcity of financial resources presents enormous potential for use of mycorrhiza, since it promotes production and consequently financial rollback.
