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