    I looked at this tree a month ago and was puzzled then. Forgot about it and misplaced my notes. Going to schedule another site visit this week but these are the pictures I took on Aug 13th.

    I have looked through all of my usual resources, and a few new ones and cannot find a good match.

    Any help would be appreciated.

    the raised areas are a leaf gall. I had some similar galls (but they didn't turn as black) on my Pin oak. I couldn't identify them. Found a very similar picture on an Arboretum website and emailed them to ask what they were...their PhD entomologist didn't know... Many, many, many leaf galls are not well identified/documented because they are insignificant to tree health.

    The other browning areas look to be Oak anthracnose.

    Thanks Joe,

    I neglected to mention that she had another Oak with significant thinning. I wanted to get a full picture of what is going on with all of her trees before I gave any recommendation.

    Also some leaf spot, possible midvein gall amongst others.
