Unfortunately, not much. These little black spots are the result of what’s commonly referred to as Artillery Fungus or Shotgun Mold. It develops in hardwood mulches around the foundation of a house and is usually a greater problem in the spring and the fall, when conditions are likely to be cool and moist. Trying to remove these spots is almost impossible and usually leaves a small brown dot. The best solution is to remove the hardwood mulch from next to the house and replace it with a different ground cover such as granite or decorative rock.
