Grayish-white bark and looks short of flakey. The fruit is longer than it is wide, about 1-1.25" in length. The leaf is has multiple long tips and it base shape is not round or oval or eliptical. It can be confused with a swamp chestnut oak, except for the size of the fruit (smaller) and the leaf. A swamp chestnut has an oval or elliptical leaf with tiny edges on it. Hope that helps!
