tuberaceae

Labyrinthomyces is a genus of truffles in the Tuberaceae family.

Instead, this narrowly defined group is most closely related to the true truffles of the Tuberaceae.

Molecular analysis of DNA sequences revealed that the species is not related to the truffle genera of the family Tuberaceae, including Tuber, Dingleya and Reddellomyces.

Phylogenetic analysis of DNA sequence data shows that within the Pezizales order, Caloscypha fulgens belongs in an evolutionary lineage with the families Helvellaceae, Morchellaceae, and Tuberaceae.

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.
