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?
