It looks like you possibly have Quince rust. The spores just aren't present right now. The galls look dry and inactive. The dead branches have been girdled by the fungus. I see this a lot on hawthorns too.

Wasn’t this asked about yesterday as a Silverberry? I was dubious about the id then.

Floral, that confused me then too. My immediate thought was Rust, but then I thought Silverberry? So yes, it is rust on a serviceberry, and you need to get it treated with antifungus tree medicine: I am speaking from experience.

Really sorry for the confusion! I always call our Serviceberry trees Silverberry. This Spring, all of the fruit had Quince Rust. When I read about it, it seemed that it only would affect the fruit and not the tree. Based on that I couldn't figure out what was going on. I appreciate the replies, what should I do now and next Spring to prevent Rust?

Call an arborist - they will be able to treat your tree, no matter how big it is, with antifungal stuff. I have had my guys, who are terrific, do the sprays and the injections, and the injections worked much better, but YMMV.

Cedar rust can’t be treated with fungicide once the symptoms are already visible; you would need to treat it preventively for the following year. Another option is to remove any nearby host cedars (if they’re on your property.)

sah - you are completely correct. I am sorry that I didn't spell that out clearly.

I'll definitely pre-treat early each Spring moving forward. Thanks

Is that a cottony substance on the leaves? I have had wooly aphids or something similar on my serviceberry trees some years - on the undersides of the leaves. One tree that I had totally died, was cut down, and then totally regrew very quickly from side shoots into a full tree again! I talked to my local nursery, and they recommended spraying with a product called “Captain Jack’s”. I did that this spring and have not seen any “wooly” residue on the underside of the leaves. - but it has been a very dry, hot summer also. Still, some of the leaves seem to turn yellowish and fall off early (early August) on some of the smaller twiggy branches. They have been doing that for years. Don’t know what’s going on...
