    What is Artillery Fungus?

    The artillery fungus resembles scaly dirt or black spots, its scientific name is “Artillery Branched Stereum” and it is mostly found growing on logs or dead wood.

    Artillery Fungus is defined as a wood-decaying fungus responsible for causing unsightly spots on objects located in its immediate vicinity. These spots are often mistaken for tar spots, scale insects, or insect frass.

    It grows slowly and can take up to five years for it to fully develop into a full body.

    What Causes Artillery Fungus to Grow on Car Paint

    1. Decaying Wood

    Decaying wood offers the most conducive environment for the Artillery fungus to grow.

    When you have some decaying wood that’s infested with artillery fungus next to your car park, the fungus may grow rapidly and land on your car.

    This is particularly the case if your car garage is cool and moist.

    2. Wood Chip Mulch

    Wood chip mulch is one of the leading causes of Artillery fungus on your car paint.

    If you have this type of mulch near your car, it accelerates the growth of this fungus, especially after a rainy stretch.

    When the fungus surfaces, it bursts and shoots small black dots, which land on anything that’s within a 25-foot radius.

    3. Infested Houses

    If your house is infested with artillery fungus, you can transfer the fungus to your car.

    When a homeowner decides to scrape, sand, or remove the fungus mess on the sides of their homes, the spores can fall on your vehicle.

    The spores are dormant but alive. So, they will thrive under favorable conditions.

    4. Infested Nursery Plants

    You can also cause artillery fungus to grow on the car paint by bringing in infested nursery plants in your homestead.

    If some spores are stuck under the leaves, they might be moved by wind and land on your car. When the leaves fall on the mulch, the cycle continues.
