We don't know what it is. We know it's everywhere on the farms. After a full season of watering on the crops, this tends to show up on the ground in certain areas. It's slimy and slippery when you walk on it. My fellow co-workers and I call them "brains" because of the obvious; they look like nasty diseased brains. I was walking amongst a "brain" patch today, and thought of how disgusting this stuff was... wouldn't this make for good props in a horror movie? :0 (Gross!)
