Unfortunately for me, here on my property, there is a strain of black mold that overwhelms most Lactobacillus, or I'd be making sourdough.

I didn't do it last fall, but sometimes in the Spring & Fall, I do the double cheesecloth over flour and water outside thing to capture wild yeast. I've never had any black mold take over. This is good because I would freak out if that happened.
