We have black spots on our vinyl siding. We have been told it is probably a fungus from previous vines that have grown on the house, or also from mulch around the house. Is there a way to tell if this could be mold? When we rub it with our fingers, spots of it rub off, and so we are n0t sure if that could be mold or not since it does that.. Thanks for the help!!
