Tuber gibbosum is the only Tuber species which is found in quantity in the spring. These appear 2-3 months from maturity. There are other species which this could be. I see no darkening of the gleba yet, nor indication of mature spores near the peridium, where they would likely mature earlier. As such, as Dr. James Trappe was fond of telling me, it is more accurately described as Tuber species. Until mature spores are present identification to species not possible. You are probably right in your identification, based on collections of Tuber submitted to NATS in past and my own experience.
