Quercus toumeyi, particularly the more spinescent-leaved form, is often confused with Q. turbinella. The latter species has acorns on peduncles greater than 10 mm, and more or less evenly distributed minute, flat, stellate trichomes on the abaxial leaf surface, in contrast to the subsessile acorns and longer straight hairs along the midvein of the abaxial leaf surface in Q. toumeyi.
