Oh sorry, no. Truffles grow as part of a symbiotic system around certain tree roots, and it's devilishly hard to recreate those conditions well enough in "captivity" if you get my drift.

Huckleberries are an interesting case and that nobody is quite sure why they fail as a crop, but at the end of the day the only way to grow more huckleberries is to clear woodland and let huckleberries grow there.
