We do apologize but there are no fungicides legally registered (labeled) for use against the artillery (shotgun) fungus so we are unable to make a recommendation. This is typically something that comes from mulch but can get on houses, trees, etc. in the area as the spores can shot up to 20 ft. There is some advice online from a Dr. at Penn State here.
