Any ideas?

Not positive what kind of oak tree this is but check out these little things on leaves.   Tried cutting into one and it's very hard to cut into. Never saw anything like it. There's a bazillion oak trees up here in Ithaca

Looks like the dreaded "wooly gall",lol

Rounded leaves belong to the white oak family, sweeter than the red or black oak family with thier pointed leaves and leaf intersections.  The red/black oak's are more acidic.

If you've got a lot of white oak consider yourself lucky.

When the trees get diseased they don't drop nuts

Yep, those are galls. Generally don't really hurt the tree.

That would be unfortunate.

Ditto what he said!!! Also, you have a gold mine there with white oak trees!!! Keep a look out for a nice spot to hang a stand!!!

It's only a goldmine if they have nuts... take a pair of.bios amd.look into the tree tops you need confirmation of ripe.nuts..my trees have dropped their nuts already due to water stress or.lack there of.. Beach nuts look good as they se to be in wetter areas that hold water better. And a certain wHite oak will be better than others why who know maybe it's sweeter but trying to hunt the right tree is most important rather than a whole grove

I wish I had these trees on the property I hunt. However these were 2.5 hours away in Ithaca and I'm in Buffalo area. Too long a shot even for an expert marksman like myself 

Sadly I have zero food source where I hunt. 

Great info everyone. Thank you
