Those are absolutely black walnuts.

They may break down, but they will poison absolutely everything they touch and be sure nothing else will grow.

My first year growing a veg garden next to that bastard tree I learned my lesson. Raised beds from then on.

Yep black walnuts are allelopathic, the secrete a chemical that suppresses plant growth around them called juglone. Its most concentrated in the roots, flower buds and hulls of the fruit

We had one of these in our back yard when I was a kid. My brother and I would throw these at each other. At first they were hard and it would sting you. But as they rotted, they would turn black and smell so bad when they hit you. You would get a black stain on your hand and on your shirt if you got hit and the smell would linger. We would throw them at the back of the shed and leave stains on it and piss off my dad.
