Oh, I meant to say that when digging out the thorny vines, I found I have a few truffles! The first one - about 1 1/2 pounds got thrown on the fire with the thorny vine tubers. Broke my heart when I found and looked up the second one, and learned that it was a truffle. The second one is thriving nicely in its 'nest' among the roots of one of the trees in my front yard.
