Pecan-associated truffle
Tuber floridanum is a truffle that grows with pecan trees in orchards of the southeastern United States and has a recorded food use in Brazil. Sources describe its odour as unappealing, and the evidence for eating it is limited.
Overview
Tuber floridanum is a truffle that forms a partnership with pecan roots. It was described in 2018 from commercial pecan orchards in the southeastern United States, and the catalogue records a food use in Brazil. The catalogue calls it the pecan-associated truffle. Its food use is newer and less documented than that of truffles with long traditions.
Identity and ecology
Tuber floridanum was described together with Tuber brennemanii. Both were among the most commonly detected ectomycorrhizal fungi in the pecan orchards studied. The catalogue records the species as ectomycorrhizal in a pecan plantation, and its supply as unknown.
Brazil
A Brazilian study reported the species as the first truffle recorded in Brazil. It described the aroma as having a composition unlike that of the commercial and non-commercial truffles analysed at that time. The occurrence in Brazil is thought to have come on the roots of imported pecan seedlings. The 2024 audit records a Brazilian food use with limited evidence, including the authors' own observations, rather than proof of wide traditional use.
Aroma and use as food
Sources describe the odour of this species as pungent and unappealing. A study of Tuber maculatum in Uruguay notes that these pungent species are generally considered unsuitable as whole foods, and suggests they could be used as a spice. The species is small, which the sources also give as a reason people are unlikely to eat it in quantity.
Safety
The sources read here establish no safe preparation for this species, and the catalogue leaves its safety for specialist review. The food-use record does not establish that the fungus is safe for everyone. This page gives no verdict on edibility.
