There are no other nearby trees this could've come from. The 3rd picture shows an exit hole. The 2nd and 4th pictures show opposite ends. In the 6th and 7th photos you can see the indentation where it grew around and attached to a stem.

It had an odd missing section, visible in the 8th picture. The 9th photo shows it as I found it while the 10th shows the host tree.
