The black truffle mycelium burns a parcel of land around the base of the host tree (generally an oak or hazelnut tree). The fact that vegetation is missing at the bottom of a tree usually means that truffles are  underneath the surface of the ground. This is called the “brulé” method.

"Mouche method"

It is also possible to find truffles by following flies. Some of them lay their eggs over truffle-growing area. Our advice, be patient and observe carefully!
