Truffle Origins: Does tree species make a difference?

Hi.

I was browsing a website selling truffles, and saw a claim that the species of tree that the truffle (melanosporum) was harvested from affected the character of the truffle.

Have any of you heard this claim before? Have you ever had the chance to sample truffles from different species of tree?

Have you ever heard of melanosporum growing on the roots of walnut trees? Does the high concentration of juglone in the roots of walnut trees affect the truffles one way or another?

Thanks!

    Definitely. I've truffle hunted several times in Europe and therefore have eaten tons of fresh truffles. We go for the prized white Tuber magnatum pico (Italy and Istria, Croatia) and occasionally Tuber melanosporum. We usually hunt in oak, poplar, beech and hazelnut. As they are underground, they are dependent on a host. Truffles have a symbiotic relationship with trees and only grow around certain ones. But they do not compete with the trees. I have not heard of them growing under walnuts but you never know.

    This year was not great for truffles due to drought, especially in Istria, so we did not hunt this time. Our house in Croatia is in the middle of Tuber magantum pico territory. The second largest white truffle ever found was in Istria and it weighed 1.3 kg and sold for 100,000 euros I believe.

      I've never heard of truffles on walnuts, either -- in France, it's typically oak, though once in a while I hear mention of the other trees that chefathoome lists.
