The Tuberaceae are a family of mycorrhizal fungi. It includes the genus Tuber, which includes the so-called "true" truffles. It was characterized by the Belgian botanist Barthélemy Charles Joseph du Mortier in 1822. A molecular study of ribosomal DNA by mycologist Kerry O'Donnell in 1997 found that a small clade now redefined as Helvellaceae is most closely related to the Tuberaceae.
