What's the name of this little green fruit?

Question

I picked this off of a tree and I'm curious about what kind of fruit it is...

It's small (smaller than a tennis ball), fairly round and hard. The skin is rough (bumpy), and light green with black speckles all over. The inside is yellow and it's got a huge pit (like a peach) in the center.

It's definitely NOT an avocado, though it sounds like one, and it's not a lime or any kind of fruit traditionally sold in grocery stores.

If it helps any the tree is in the northeast of the US.

Answer 1

Could the fruit you are describing be a mango? The tree would not be native to the Northeast. The other which is green with a rough exterior is an Osage Orange. It is neither orange or edible.

Answer 2

green apple??? IDK

Answer 3

Sounds like a Sweet Gum Tree dropping its seeds.

Answer 4

Is it the fruit of a black walnut?
