It sure is! As I was wondering what it was all over those leaves. I had also noticed that it was on only that one species of Oak. That's why I took the picture, because it had my full attention.
Now he did state, that a Gall on another tree that was caused by Wasp was almost nut size, very rough and dark brown. And in clusters. So now, if I run across that somewhere else, I'll know.........
Thank you for your help.

Was told by Missouri Dept. of Conservation Naturalist that these Galls are caused by Midges.

Oak leaf galls possibly produced by Cynipidae wasps.
