WHAT IS A MYCORRHIZA?
The word mycorrhiza comes from the greek mukes, which means mushroom and the word rhiza which means rooot.

A mycorrhiza is the symbiotic association of the root of a higher plant with a fungus. (FRANK 1885)

There are several types of mycorrhiza, but our activity refers mainly to ectomycorrhizae and endomycorrhizae.

Ectomycorrhizae are found only in a proportion of 3 to 5% in terrestrial vegetation, but they have a significant importance in forest ecosystems.
They have a more or less narrow specificity of the host-species or the soil and represent a real interest in the production of edible mushrooms. Ectomycorrhizae can be recognized with a binocular magnifying glass, by analyzing the root system infected with mycorrhize.

They refer to:

Mycorrhized fungus that represents forestrial interest like: Laccaria, Hebeloma, Suillus, Paxillus, Rhizopogon, Pisolithus found on a large variety of conifer and decidous hosts.

Mycorrhized edible fungus like Lactarius, Suillus, Boletus, Ammanita, Cantharellus, including underground species, Tuber melansoporum, Tuber uncinatum, Tuber magnatum, found more or less at host-species like Pinus, Picea, Abies, Quercus, Corylus, Castanea, Tilia, Populus, Cedrus.

Endomycorrhizae represents the most frequent symbiosis form that colonizes over 90% of terrestrial plants. They refer especially to ornamental species or fruit bearing species, but at the same time they are associated with forestrial species like Fraxinus, Acer, Juglans, Prunus.
