what kind of tree do truffles grow under
Truffle The mycelia of truffles form symbiotic, mycorrhizal relationships with the roots of several tree species including beech, birch, hazel, hornbeam, oak, pine, and poplar.[20][21] They prefer argillaceous or calcareous soils that are well drained and neutral or alkaline.[22][23][24] Truffles fruit throughout the year, depending on the species, and can be found buried between the leaf litter and the soil.
