What is Shotgun Fungus?

Shotgun fungus (also known as Sphaerobolus, artillery fungus, and cannonball fungus) can be found in mulch, soil, and other organic matter. This fungus earned its name because it shoots tiny black balls (spores) onto nearby surfaces like houses, cars, and plants. 

Removing these spores can be challenging and cause unsightly black spots on affected surfaces. Shotgun fungus thrives in moist environments and is commonly found in warmer months.

Regularly turning and aerating mulch is essential to prevent this fungus’s growth.

What Causes Shotgun Fungus On Car?

The shout gun spores can be propelled by water droplets, such as rain, or by the force of the fungus’ expansion from areas where the fungus is likely to grow, such as rotting wood, house siding, moist landscape mulch garden, beds or wooded areas.

Once they land on a surface, they adhere tightly and can be difficult to remove without causing damage. When Artillery Fungus spores land on a car, they can be unsightly and difficult to clean and may even cause damage to the paint or other surfaces if left in place for too long.
