It’s leaf gall, a fungus know as Exobasidium vaccinii. It needs to be cut off and any others as well. What’s the situation like for irrigation? Mulch? Any other spots like this? It’s also contagious to other plants so be sure to wash your hands thoroughly after handling it.

Thanks for the diagnosis! It's a shady area that often stays damp after rain. I put down new mulch a few months ago.
I guess I'll just cut off the affected areas? Are the green growths under the leaves the same thing?
I would probably prune that whole stem, just to be safe. You may also want to replace the mulch under it to remove any spores hidden in the old mulch.
