Observation 209782: Tuber P. Micheli ex F.H. Wigg.

Found beneath native hazel nut bush, Corylus americana, and no other hosts nearby as it’s a commercial plantation of them. Several specimens. Largest one is about size of the last digit on your pinky finger (male). Very strong truffle aroma, similar to mature Oregon white truffles.

Habitat For Tuber lyonii.

Tuber lyonii associates with a wide variety of hosts from Mexico City north to Quebec, from Florida at least west to Arizona (and probably the entire West Coast as well). Hosts include pecan, heartnut, hazelnut, oak, hawthorne, basswood, and many other tree species. T. lyonii seems to reach its largest size when associated with pecan, and has been called the Pecan truffle.

BTW, Corylus cornuta var. california (California hazel) is also a native hazelnut, and hosts many Tuber species as well.

I hope you plan on doing microscopy, Britt. This looks similar to Tuber candidum, T. maculatum and T. shearii. T. maculatum is known from your area, and is also associated with hazel, so must be considered in the mix of possible fungi here.

without question. I’d suspect Tuber lyonii, which can associate with many, many trees and shrubs. Here’s the rub: Tuber lyonii looks completely different when associated with different hosts.
