Black on japanese maple identification

Good day, this is a home depot type sango kaku in my garden that is unwell. Pseudomonas syringae or Verticillium wilt?

Must have happened during this summer or fall.

My guess is P. Syringae. Here is an article that may be helpful.

Thanks, after some further searching the forum I found this post: https://www.bonsainut.com/threads/terminally-ill-sango-kaku.34205/post-570501

I keep my more developed JMs in a better environment than my cheap ground grown plants. I think this sango will meet its fate tonight

This plant was sacrificed in the name of science. Not really looking too much like verticillium wilt does it?

Verticillium presents as wilt, not blackening. It does darken vascular tissue, but you'd notice the foliage wilting before you see anything presenting on the bark/trunk.
