These peridioles are forcibly ejected from reproductive structures, or fruiting bodies, of the fungus. Distribution Sphaerobolus is distributed in most temperate climates throughout the world. The fungus grows on manure, rotting wood, or other organic matter, and is often found on tanbark and wood chips in mulched foundation plantings. It is most prolific in open areas that are not too shady. The fungus also requires adequate moisture to complete its life cycle.
Fungal populations tend to be higher in areas that have a northwest exposure.
Occasionally, this fungus is found indoors associated with mulched potted plants, and in the greenhouse on old wooden benches or other rotting wood. Life History Sphaerobolus fruiting bodies, approximately 2 mm in diameter, appear in large numbers on rotting wood as spherical, white or yellow globes that resemble tiny puffballs. A single peridiole, which is 1 mm in diameter, is produced inside and sits in liquid at the bottom of the cup. Several hours later the cup is violently turned inside out, catapulting the peridiole into the air. Sphaerobolus is strongly phototrophic and will shoot its peridioles toward the strongest source of light, which can be any reflective surface such as the siding on a building or the bumper of a car.
