Calcareous soils with partner trees such as oak, beech, hornbeam or hazel. The fruiting body develops underground.
The autumn form mainly matures from September into winter, with local variation in phenology.
Identification and lookalikes
Other Tuber species, immature truffles and false truffles from other genera can be confused. Smell, outer colour or a map confirms neither species nor maturity. A cut surface and competent inspection are needed.
The map helps you search. Never identify.
Cepello does not identify mushrooms and never confirms that a specimen is edible. Have your entire collection checked by an official inspection service.
