Yes, in fact the cultivated truffle industry is starting to get going now. In the past few years, farmed truffles have appeared on the market. I tried truffles for the first time a month ago and they came from Australia, presumably one of the new farms there.
The history of this is pretty fascinating.
Truffles grow in the roots of certain oak trees. To cultivate them, you need to plant those trees, carefully protect them from other undesired fungi, and wait 7 to 10 years for the fungus network to mature in the trees roots. Any given tree has an active lifecycle of only about 30 years, so after that, you have to replant. This process was figured out in the late 1700s. By the 1800s, there were over 100,000 acres of truffle farms in France, and truffles were a reasonably priced easily available foodstuff.
Then WWI hit. 20% of the male workforce was killed and many others had left rural areas and moved into cities. Without expertise and available labor, many truffle fields were lost. This is when they became a rare expensive luxury.
In the past few decades, after truffles became fashionable, cultivation has started again. It's only in the past few years that these new fields have begun to sell product. Going forward, you can probably expect real truffles to become more common and less expensive.
Oh, and the truffle I tried was shaved on top of a mushroom risotto. It's possibly the best tasting thing I have ever eaten.
