Hi! I'm new here, so please forgive my general ignorance. Thanks in advance for your help. We live in a pecan grove converted into a community in Queen Creek, Arizona (suburb of Phoenix). We were walking around the yard today inspecting the trees (as if I knew what I was looking for) and noticed what looks like a tree fungus to me. After looking closer, it looks like something is using the growth as a nest and burrowing into the tree. Maybe. I'm clueless. I posted pics below. Is this something I should treat or get help with? Let me know if you need more information, and again, I really appreciate the advice. Thank you!
