Notes: Even when immature, the smokey black gleba of Tuber gibbosum is visible through the peridium (outer truffle skin). When completely mature, T. gibbosum can be so black as to be nearly the same color as Leucangium carthusianum, as I hope these photos demonstrate. In addition, Tuber oregonense is never grayish in the gleba, so a quick fingernail scratch should be able to distinguish these two species even in the field.
