My guess is it is Pecan, I have had lots of spalted Pecan and it looks very much like this. Also the area of the country your in would re-enforce my belief.
Looks good Chris, good form, nice figure. I would have liked a bit more rounding into a small foot, but that will come. A round bottom with a small foot will lift the piece off the table and make it appear to float off the surface. Keep it up!
