As mentioned above truffle is part of the fungus family, growing with the roots of certain trees. What sets them apart from other mushrooms is not that they grow underground, but that they have a symbiotic relationship with trees. They attach to the roots of trees and issue long tendrils that gather nutrition for the plant. The carbohydrates that are returned from the host tree eventually form the “fruit” – the truffles. The white truffle can reach 12 cm diameter and a weight of 500 gr.
