There were a few of these last year, but it's covered this year. The
leaves are covered with black powder also, some kind of

Do I need to do anything with it?

The black lumps are aphids, a pretty bad infestation from the looks of
it. The black powder on the leaves is sooty mold, growing on the
sugary excretia of the aphids.

Aphids? I never would have guessed that. Thanks for the help, I can
always count on austin.gardening.
