There is a great diversity of plants and fungi that naturally form mycorrhiza. More than 700 species of fungi are known to establish mycorrhizal relationships with vegetables. From an anatomical point of view we can differentiate between two major types of mycorrhizae:
Ectomycorrhizae, which are more frequent in tree roots, and which significantly modify their branching. More than 2,900 species of vascular plants form ectomycorrhizae. 95% of ectomycorrhizal species (pine, fir, Douglas fir, larch), 94% of fagaceae (beech, holm oak, hazelnut, chestnut, etc.) are 90% Of the mirtáceas (eucalyptus) 83% of salicáceas (willows, poplars …) 70% of the betuláceas (birches) many ulmaceae (maples), juglandáceas (walnuts) cistáceas (rock roses, Cistus and Helianthemum …) In other words, ectomycorrhizas form practically all trees (95%) and many shrubs of interest in the temperate forests of the Northern Hemisphere, including the Mediterranean ones.
Endomycorhizae, usually in shrubs and herbaceous plants that do not modify the external appearance of the root, although its internal morphology. Plants that basically form endomycorrhizas: leguminous (apiaceous), rosacea, oleaceous, euphorbiaceous, scrophulariaceae. Rubiaceous, cyperaceae, grasses (poaceae) and composite (fabaceae). That is, most of the crops, fruit trees and plants for gardening, as well as the natural herbaceous stratum of many ecosystems of the planet are endomicorrícicos.
