So I made a mistake. I said there was a walnut tree in my backyard, but when I looked at the leaves on the ground and the pods on the trees, they did not match that of a walnut.

As for the pods, they are spherical, about an inch in diameter, and they have a rough light brown surface.
I honestly do not know what it is.
