Default What's The Substance On My Two Hybrid Elm Trees?

Same thing happened last October, but not in prior years. Elms
planted about 25 years ago. Researched a dozen "tree" books; found
nothing. What is this substance? Thank You.

Sooty mold is the only thing that comes to mind from the discription.
Good luck
