Pecan truffle abundance swings wildly even within one orchard

Pecan truffles, a prized edible fungus that grows underground near pecan tree roots, don't spread evenly through an orchard. A new study found truffle DNA levels varied by over 50,000-fold between different sections of the same orchard, with younger trees surprisingly hosting the most truffle growth.
