Thank you for your question. These are spindle galls, created by mites, that do not harm the leaf or tree. You can read about them here: http://hortsense.cahnrs.wsu.edu/Public/FactsheetWeb.aspx?ProblemId=832

Thanks very much! It's a big relief to know the mites and galls won't case damage to the trees. Whew!

Yes; they look worse than they are!
