Artillery fungus can be a nuisance for homeowners, but you can manage it with the right approach. These tiny fungi shoot spores onto surfaces, leaving unsightly black spots that can be difficult to remove. Understanding how to identify and prevent artillery fungus helps maintain the beauty of your property.
Inspect mulch beds regularly, as they often harbor this fungus. Consider using alternative ground covers, like stone or rubber mulch, to reduce the risk. With mindful observation and proactive measures, artillery fungus becomes less of a threat to your home’s exterior.

Artillery Fungus: Identification and Prevention
Artillery fungus, often found in mulch, can be a nuisance for homeowners. This small, wood-decay fungus shoots spore masses that can stick to surfaces like cars, siding, and even windows, leaving unsightly black spots. Let’s dive into understanding how to identify this pesky fungus and ways to prevent it from taking over your outdoor spaces.
Understanding Artillery Fungus
Artillery fungus, or Sphaerobolus stellatus, loves to grow in moist, decaying organic material, particularly mulch. It gets its name from its powerful ability to “shoot” spores up to 20 feet away. These spores, also known as gleba, are sticky and can be difficult to remove once they adhere to surfaces.
Characteristics of Artillery Fungus
– **Size and Shape**: The fruiting body of the fungus is tiny, usually less than 0.1 inches in diameter. It resembles a small cup or saucer.
– **Color**: The spore masses are dark, typically black or brown, making them visible on light-colored surfaces.
– **Shooting Mechanism**: The fungus uses a unique mechanism to launch its spores, relying on sunlight to aim the discharge. This is why you often see spore spots on sunny sides of homes or cars.
Common Habitats for Artillery Fungus
Artillery fungus thrives in certain environments, mostly where organic material is plentiful and moisture is present. Here are some common habitats:
- Mulch Beds: Especially common in wood-based mulches, where decaying matter provides an ideal food source.
- Shaded Areas: Though it prefers sunlight for shooting spores, the fungus itself can grow in shaded, moist areas.
- Decaying Wood: Old stumps, logs, and wood piles can serve as breeding grounds for the fungus.
Identifying Artillery Fungus
To deal with artillery fungus effectively, you must first be able to identify it. Here are the signs to look for:
Signs of Infestation
– **Black Spots on Surfaces**: Look for small, black tar-like specks on cars, siding, and windows. These are spore masses.
– **Presence in Mulch**: If you see the small, cup-like fruiting bodies in mulch, you likely have an infestation.
– **Seasonal Appearance**: Artillery fungus is most active in the spring and fall when conditions are moist and cool.
Preventing Artillery Fungus
Prevention is the best strategy to keep artillery fungus at bay. Here are some effective methods:
Choosing the Right Mulch
– **Avoid Wood-Based Mulch**: Since artillery fungus thrives in wood, try using alternatives like pine bark, cypress, or hardwood mulch.
– **Use Inorganic Mulch**: Consider rocks, gravel, or rubber mulch, which do not support fungal growth.
Proper Mulch Maintenance
– **Regularly Turn Mulch**: Turning mulch helps to dry it out and disrupts fungal growth.
– **Replace Old Mulch**: Every year or two, replace old mulch to minimize decaying material that feeds fungus.
Environmental Controls
– **Improve Drainage**: Ensuring good drainage around mulch beds will help reduce moisture, making it less hospitable to the fungus.
– **Increase Sunlight Exposure**: Trim back overhanging branches to allow more sunlight to reach mulch beds, reducing moisture levels.
Dealing with Artillery Fungus Spots
Unfortunately, once the spores have adhered to a surface, they can be difficult to remove. Here’s how you can address them:
Cleaning Techniques
– **Physical Removal**: Scraping the spots with a plastic scraper can help, but be careful not to damage the surface.
– **Use of Cleaners**: Some homeowners find success with cleaning solutions like vinegar or a mixture of water and baking soda. Test on a small area first.
Professional Cleaning Services
– **Pressure Washing**: In some cases, pressure washing can remove spores, but use caution on delicate surfaces.
– **Professional Products**: Some companies offer specialized cleaning products designed to tackle artillery fungus spores.
Long-Term Management Strategies
Once you’ve dealt with an initial outbreak, implementing long-term strategies can help prevent future infestations.
- Regular Inspections: Regularly check mulch and other potential breeding grounds for signs of fungus.
- Educate Yourself and Others: Understanding the lifecycle and habits of artillery fungus can help in early detection and prevention.
- Community Efforts: Work with neighbors to manage mulch and landscape practices, reducing the overall spore load in your area.
Understanding and managing artillery fungus requires vigilance and a bit of effort. By identifying the signs early and taking preventative measures, you can minimize its impact on your home and outdoor spaces. Remember, the key to control lies in choosing the right mulch, maintaining your landscape, and addressing any infestations promptly.

Frequently Asked Questions
What are the signs of an artillery fungus infestation?
Artillery fungus, or Sphaerobolus, is often identified by its small, black, tar-like spore masses that stick to surfaces such as siding, cars, and windows. These spores are difficult to remove and usually appear as tiny black spots that resemble specks of dirt or tar. If you notice an unusual number of these spots on the north side of buildings or on light-colored surfaces, it might be an indication of artillery fungus.
How can I prevent artillery fungus from spreading in my garden?
To prevent the spread of artillery fungus, avoid using wood mulch, especially if it’s not well-composted, in areas close to buildings or vehicles. Instead, consider using alternative mulching materials like stone, gravel, or synthetic mulches. Ensure proper drainage in your garden to reduce the moisture levels that favor the growth of these fungi. Regularly turn and aerate mulch to promote drying and decomposition, which can minimize fungus activity.
Can you remove artillery fungus spores from surfaces?
Removing artillery fungus spores can be challenging due to their sticky nature. For siding or cars, try using a mixture of water and mild detergent, along with a soft brush or sponge, to gently scrub the affected area. In some cases, power washing may help, but be cautious as it can damage surfaces. For stubborn spots, commercial cleaning products designed for tar or sap removal might be effective. However, complete removal might not always be possible, and prevention is often the best strategy.
Does artillery fungus pose any health risks to humans or pets?
Artillery fungus does not pose direct health risks to humans or pets. The main issue with artillery fungus is its ability to create unsightly black spots on surfaces, which can be difficult to clean. While the fungus itself is not harmful, its presence can be a nuisance, particularly when it affects the appearance of homes and vehicles.
Are there any specific environmental conditions that favor the growth of artillery fungus?
Artillery fungus thrives in moist, shady environments, which are often found in mulch beds. The fungus tends to be more active during cool, wet periods in spring and fall. Areas with high humidity and low sunlight, such as the north side of buildings or under dense foliage, provide ideal conditions for its growth. By managing moisture and sunlight exposure, you can reduce the likelihood of artillery fungus developing in your garden or landscape.
Final Thoughts
Identifying and preventing artillery fungus helps maintain a clean and appealing outdoor environment. Regularly inspect your mulch and choose resistant types to minimize the risk. Remove any contaminated mulch promptly and replace it with fresh material.
Implementing these proactive measures ensures your property remains free of unsightly spores. By staying vigilant and informed, you can effectively manage artillery fungus: identification and prevention are key to maintaining your landscape’s beauty.
