Can you identify

Asked July 2, 2019, 11:55 AM EDT

I had some pictures sent to me via email. They would like to know what is going on with their Maple tree. I think there is two different problems happening. The first two pictures look like Maple tree Gall, the third looks like tar spots. I would just like a confirmation or an answer. Thanks,

Yes, gall mites are the culprits of the deformities in the leaves. The dark spots do appear to be tar spot. Neither the tar spot nor the mites are a cause for concern. Check out the following links:
