Yes, it’s time for a Fall Gall edition. These are the structures created by the tree, in this case, in response to insects (in these cases) who lay their eggs on the tree. This one is, I think, a Hedgehog Gall.
Not sure on this species.
Nor this. This one was much smaller and looked like felt.
This one white oak in Green-Wood has at least four gall-forcing species on it. These three were evidenced on fallen leaves and twigs. (Here’s the fourth.)
