Oriental Pear leaf issues

Asked October 21, 2019, 10:32 AM EDT

I found several leaves with these nodules on my oriental pear tree. This is the second year the tree has borne fruit, and otherwise appears healthy. What is it? Do I need to treat?

These appear to be galls, but we need to study them more to ascertain the species.
We would be very appreciative if you would send a sample to:

Thank you. I mailed 12 affected leaves today. They should arrive Friday.
