Why does my orange tree have thorns? I?

Question

My orange tree looks like 2 trees in one. Could something have grafted to it by mistake? If so what do I do?

Answer 1

What kind of orange do you have? We have a small tree, a "hardy orange" I think it's called, that produces small inedible (I think?) fruit that become a yellow-orange and lightly fuzzy. It DOES have thorns.

Answer 2

it might be a type of fungus
