This recently described truffle was found scattered amongst an oak-dominated forest from mid-Summer through late Fall when the first frosts began to set into the landscape of Mid-Michigan. Formerly known only as Tuber sp. 47, the group which described this species was finding this truffle frequently in Florida and also noted its presence on pecan roots in a Brazil plantation (Grupe, 2018).
This truffle, as with all truffles, grows hypogeously below ground. When mature, it produces a distinct, almost nutty odor. The sandy-loam soils this truffle was found in have a pH of 7.5 and were recently disturbed by farm equipment. Truffles seen in Figure 1 only represents three of around 60 T. floridanum truffles found at this site in 2018. One of the close look-alikes to this truffle is T. arnoldianum which can be distinguished by the tenancy for T. arnoldianum ascospores to be longer (23–51 μm) than T. floridanum ascospores (18–47 μm)(Grupe, 2018).
