All the leaves on our mature tree have developed these nodules. They are solid. We only noticed them about 10 days ago. I wrote you a week ago but haven’t gotten a response. We live behind Angostua Reservoir near the dam.

Expert Response
Hi Cathryn,
Do you know what kind of tree this is? If it's a hackberry, it could be hackberry nipple gall. Our Extension forestry specialist, Dr. John Ball, wrote a Tree Pest Alert article about hackberry nipple gall that I have attached. If you have further questions, you can contact him directly at <personal data hidden> (cell).
Sincerely,
Robin
This solved our mystery. Thank you. Cathryn
