Understanding Stinkhorn Mushrooms

Stinkhorn mushrooms are a type of fungus that belong to the Phallaceae family. They are named after their peculiar shape, which often resembles a phallic structure. Despite their offensive odor, stinkhorn mushrooms serve a crucial role in natural ecosystems by breaking down decaying organic matter. They thrive in damp environments and can appear in your garden, lawn, or even on rotting wood.

One of the most distinctive features of stinkhorn mushrooms is their foul smell. This odor, often compared to the scent of rotting meat, is intended to attract flies and other insects that aid in spore dispersal. While the smell can be overpowering and unpleasant for humans, it is an essential adaptation for the survival of these fungi.


Proper identification of stinkhorn mushrooms is crucial before you begin any removal or preventive measures. Here are some key characteristics to help you identify these fungi:

Physical Appearance

Stinkhorn mushrooms typically have a long, slender stem with a bulbous or egg-shaped structure at the top. This structure, known as the “head” or “cap,” contains the spores. The color of the cap can range from white to pink, orange, or brown.

When mature, the cap may develop a slimy or sticky texture. It is in this mature state that the stinkhorn mushroom emits its distinctive odor. The length of the entire mushroom can vary, but it is not uncommon for it to reach heights of 6-10 inches.

Growth Habit and Location

Stinkhorn mushrooms thrive in moist, organic-rich environments. They are commonly found growing in gardens, lawns, mulched areas, compost piles, and even on rotting wood. These fungi are more likely to appear during warm and humid periods, typically late spring or early autumn.

The appearance of stinkhorn mushrooms may initially start as small, white oval structures emerging from egg-like casings in the soil. As they mature, they elongate and develop their characteristic shape and smell.

Risks and Concerns

While stinkhorn mushrooms are not typically harmful to humans or pets, their offensive smell and unsightly appearance can present an issue. Additionally, the spores produced by these mushrooms can spread easily and lead to the growth of more mushrooms, exacerbating the problem. It is important to address the issue promptly to prevent the mushrooms from spreading and to maintain the aesthetic appeal of your outdoor space.

Caution should be exercised when handling stinkhorn mushrooms or their spores. Although rare, some individuals may experience skin irritation or allergic reactions upon contact. It is advisable to wear gloves when removing or disposing of the mushrooms and to thoroughly wash your hands afterward.

Removal Methods

Now that we understand the nature of stinkhorn mushrooms, let’s explore effective methods to eliminate them from your property:

1. Manual Removal

The most straightforward approach to remove stinkhorn mushrooms is to manually pick them out of the ground. Ensure that you wear gloves to avoid direct contact with the mushrooms and their spores. Gently grasp the stem near the base and pull it out from the ground.

If the mushroom is too mature and begins to release spores upon contact, place it directly into a trash bag to prevent further spread. Dispose of the bag in an outdoor waste bin to prevent any lingering odor from infiltrating your home.

Note that manual removal is best suited for small-scale infestations. If you’re dealing with a widespread problem, consider combining manual removal with other methods for better results.

2. Improve Drainage

Stinkhorn mushrooms thrive in damp and humid conditions. By improving the drainage in your garden or lawn, you can create an environment that is less favorable for these fungi. Ensure that water does not accumulate or pool in your outdoor spaces, as excessive moisture can encourage mushroom growth.

Consider adding organic matter, such as compost or well-rotted manure, to improve soil structure and drainage. Additionally, aerating the soil and regularly removing any debris or vegetation can help prevent the buildup of moisture.

3. Remove Infested Mulch or Wood Chips

If you have mulched areas in your garden or yard, inspect them for signs of stinkhorn mushrooms. If you spot any, remove the infested mulch or wood chips and dispose of them properly. This will help eliminate a potential source of spores and prevent future mushroom growth.

Be cautious when removing the infested mulch to avoid inadvertently spreading the spores. Place the infested material directly into a sealed bag and dispose of it in an outdoor trash bin or compost pile.

4. Fungicide Treatment

In severe cases or when other methods fail to eliminate stinkhorn mushrooms, fungicide treatment can be used as a last resort. It is important to choose a fungicide specifically labeled for use on fungi and follow the instructions carefully.

Fungicides containing active ingredients such as chlorothalonil or mancozeb can be effective in eradicating stinkhorn mushrooms. However, it is important to keep in mind that these chemicals may also harm beneficial fungi and organisms in the soil. Use fungicides sparingly and as a last resort to minimize potential harm to the ecosystem.

Apply the fungicide according to the manufacturer’s instructions, typically by spraying it onto the affected areas. Ensure that you wear protective clothing, including gloves and a mask, during the application process. After treatment, monitor the area closely and repeat applications if necessary.

Prevention Tips

While removing existing stinkhorn mushrooms is crucial, taking preventive measures can help minimize the likelihood of their return. Here are some tips to prevent stinkhorn mushrooms from becoming a recurring issue:

1. Maintain Good Garden Hygiene

Regularly clear away fallen leaves, plant debris, and other organic matter that can serve as a food source for stinkhorn mushrooms. By keeping your garden clean and free of decaying vegetation, you remove potential breeding grounds for these fungi.

Dispose of garden waste properly by composting it in a designated compost bin. Proper composting practices, such as maintaining the correct balance of carbon and nitrogen materials, can help prevent the growth of stinkhorn mushrooms.

2. Avoid Overwatering

Overwatering your garden or lawn can create the ideal conditions for stinkhorn mushrooms to thrive. Be mindful of watering practices and ensure that you only provide the necessary amount of water for your plants. Consider using drip irrigation or soaker hoses to target specific areas and reduce excess moisture.

Regularly monitor the moisture levels in your soil and adjust your watering schedule accordingly. Pay attention to any areas that tend to retain water for prolonged periods and take steps to improve drainage in those areas.

3. Choose Resistant Plant Species

Some plants are more susceptible to stinkhorn mushroom growth than others. When planning your garden or landscape, opt for plant species that are less likely to attract these fungi.

Research which plants are known to be resistant to stinkhorn mushrooms or consult with local gardening experts for specific recommendations. By selecting the right plant species, you can reduce the likelihood of encountering stinkhorn mushroom infestations.

4. Regularly Inspect and Address Issues

Perform regular inspections of your garden or yard to spot any signs of stinkhorn mushrooms early on. Promptly address any emerging mushrooms to prevent them from spreading and to minimize the impact on your outdoor space.

Remember that early detection and intervention are key to preventing larger-scale infestations. By staying vigilant and taking immediate action, you can nip the problem in the bud before it becomes overwhelming.
