Hello Mark -
Maples are often infected with fungal diseases.  To find out which of them your maple is infected with, I suggest sending a sample to the MSU lab.  For a small fee, they will diagnose your maple's disease for you.  https://www.canr.msu.edu/pestid/
Here is a link that explains the different pathogens and their treatment.  https://www.canr.msu.edu/news/maple_leaf_blister_and_anthracnose_two_foliar_diseases_that_can_appear_on_s

Good luck with your maple.
