Summer truffles are in deed black truffles. While they do have a black exterior they are white fleshed on the inside, and as stated are far less aromatic and pungent, not to mention much less expensive. Compared to black winter truffles that are black on both the exterior and interior. Fresh white truffles are only available in the fall. If look back to the posted photos you will notice the distinct difference in color between the outer layer and flesh of the truffle. In New York they are available at most gourmet stores such as Dean & Deluca and the like (about $15/oz).
