Stinkhorn mushrooms are commonly found near mushroom sheds and are known for their unpleasant odour, which resembles that of rotting meat. They are reddish-orange in colour and can grow up to 8 inches (20 cm) tall. These mushrooms emerge from egg-like structures in mulch or other damp, decomposing material. While they do not harm plants or cause disease, their strong smell can be off-putting to people. Stinkhorn mushrooms break down organic matter, contributing to the recycling of plant debris and improving soil fertility. However, their presence near mushroom sheds can be a nuisance, leading to complaints and legal battles with nearby residents.

Stinkhorn mushrooms: their smell attracts insects that spread spores
Stinkhorn mushrooms are fungi that are found in both tropical and temperate regions. They are characterised by their unpleasant odour, which is often described as a putrid, rotting meat smell. This odour is produced by the mature stinkhorn, which is coated in a spore-containing slime. While the smell repels people, it serves the important function of attracting insects, particularly flies, that feed on the slime and inadvertently carry the mushroom's spores to new locations. This process is comparable to the distribution of pollen by bees.
Stinkhorn mushrooms start out as white, egg-like structures in mulch or other damp, decomposing organic matter. They can also be found in lawns and areas with bare soil. Most of the fungal structure is underground, and when enough water is available, the egg-sac structure will rupture, and the mature mushroom will emerge. Stinkhorns develop rapidly, sometimes growing up to four to six inches per hour, and can generate enough force to break through asphalt.
The smell of stinkhorn mushrooms is the result of the volatile chemicals emitted from the spores. These chemicals are detected by invertebrates, such as flies, bees, and beetles, which then feed on the spore mass. The ingested spores are dispersed via the foraging invertebrates' excrement or are transported to new sites attached to the invertebrate's body. In this way, stinkhorn mushrooms ensure the spread and maintenance of genetic diversity as the insects move from one mushroom to the next.
While stinkhorn mushrooms are often considered unwanted additions to home gardens due to their unpleasant odour and visually shocking appearance, they do not cause plant disease and can be beneficial. Stinkhorns break down organic matter, contributing to the recycling of plant debris into nutrients that improve soil fertility and can be used by garden plants. They are especially helpful in landscapes with naturally sandy and nutrient-poor soils.

Stinkhorns are beneficial: they break down rotting material into nourishment for plants
Stinkhorns are mushrooms that are found in both tropical and temperate regions. They are characterised by their unpleasant odour, which some people describe as a putrid, rotting meat smell. They are often considered unwanted in gardens due to their strong odour and unusual appearance, which can vary from horn-like to penis-like shapes. Some species even have multiple appendages, resembling an octopus.
Despite their unsightly appearance and offensive smell, stinkhorns are beneficial to the ecosystem. They grow on dead organic material, breaking it down into nutrients that improve soil fertility. This process is especially advantageous for landscapes with naturally sandy and nutrient-poor soils, such as Florida. By breaking down organic matter like mulch, stinkhorns make essential nutrients available for plants to absorb.
Stinkhorns start out as white or reddish-orange, egg-like structures in mulch or other damp, decomposing material. When sufficient water is available, the egg-sac structure ruptures, and the mature stinkhorn mushroom emerges. The foul odour produced by the mature stinkhorn attracts flies and other insects, which then pick up and carry the mushroom spores to new locations, aiding in the dispersal of the fungi.
While stinkhorns may be undesirable from an aesthetic and olfactory perspective, they do not cause plant disease and are not harmful to landscape plants or grasses. They are short-lived and will naturally disappear within a few weeks. Homeowners can take comfort in the fact that stinkhorns are seasonal and typically appear only once or twice a year, especially during wet and cool weather.
In summary, despite their unpleasant odour, stinkhorns play a beneficial role in ecosystems by breaking down rotting organic material and converting it into nourishment for plants, thereby contributing to improved soil fertility and plant growth.

Stinkhorns are edible: they are nutty and can be good if cooked right
Stinkhorn mushrooms are known for their unpleasant odour, which some people describe as a putrid, rotting meat smell. They are reddish-orange mushrooms that can resemble a wiffle ball, an octopus, or a straight stem. Despite their offensive smell, stinkhorns are edible and can be quite tasty when cooked properly. In fact, some people describe the taste as nutty.
Stinkhorns are often found in gardens and yards, particularly in mulch beds or other areas with decomposing organic matter. They can be a nuisance to gardeners due to their strong odour, but they are not harmful to plants and can even be beneficial by helping to break down organic matter and improve soil fertility. However, because of their smell, many people want to get rid of them. Unfortunately, there are no chemicals or sprays that are effective at removing stinkhorn fungi. The best way to deal with them is to remove the decaying organic matter that they grow on, such as underground stumps, dead roots, and sawdust.
Stinkhorns are short-lived and will naturally disappear quite rapidly. If the smell becomes too strong or they attract too many insects, they can be plucked from the ground and discarded. However, it is important to note that removing stinkhorns will not eradicate them. The stinkhorn hyphae will remain in the soil or mulch and will eventually produce more stinkhorn mushrooms.
So, if you come across stinkhorns in your garden, you may want to try cooking them instead of throwing them away! Of course, it is always important to properly identify any wild mushroom before consuming it to ensure it is safe to eat. While stinkhorns are edible, other similar-looking mushrooms may not be.
In conclusion, stinkhorns may have an unpleasant odour, but they are edible and can be quite tasty when prepared correctly. They are known for their nutty flavour and can be a unique and interesting addition to your meal.

Stinkhorns are seasonal: they appear for a few weeks once or twice a year
Stinkhorns, also known as stinkhorn mushrooms, are fungi that are known for their unpleasant odour, which some people describe as a putrid, rotting meat smell. They are often considered unwanted additions to gardens and yards due to their strong odour, but they do not harm plants or cause plant diseases. Instead, they contribute to the recycling of plant debris into nutrients that improve soil fertility.
Stinkhorns are seasonal and typically appear for a few weeks, once or twice a year, especially during wet and cool weather. They are short-lived and will naturally disappear quite rapidly. However, their presence can be bothersome to homeowners, and they may attract insects and other pests.
The stinkhorn's smell serves a purpose—it attracts ants and flies, which then pick up and carry the mushroom spores to other places, aiding in the spread of the fungi. This is especially beneficial in landscapes and gardens with naturally sandy and nutrient-poor soils, as stinkhorns help break down organic matter and make nutrients available for plants.
While stinkhorns can be beneficial, some people may want to remove them due to their unpleasant odour. There are no chemicals or sprays effective at removing stinkhorn fungi. Homeowners can remove decaying organic matter, such as sawdust piles, dead roots, and underground stumps, as stinkhorns grow on rotting organic material. Additionally, the fungi grow on decomposing hardwood mulch, so replacing it with pine needles, straw, or chopped leaves may help prevent their growth.
Stinkhorns are also edible and can be consumed by humans. While they may have an unpleasant odour, they are described as nutty and can be good to eat if cooked properly.

Mushroom farms: residents have complained about the odours produced and sued the farms
Mushroom farms have been a source of controversy for residents living in nearby areas, with complaints about the odours produced and even lawsuits filed against the farms. One notable case involves Greenwood Mushroom Farms, located near the village of Ashburn, about 65 kilometres northeast of Toronto. The farm, one of Canada's largest mushroom producers, has been locked in a legal battle with residents who have launched a $10 million lawsuit due to the putrid smell emanating from the farm.
The residents of Ashburn have documented the odours produced by the farm through daily logbooks and the use of "nasal rangers", devices that detect the presence of airborne compounds that produce smells. They describe the odour as "putrid, rancid, and nauseating", claiming that it has devalued their homes and severely impacted their quality of life. One resident, Ken Giles, who lives about 1.5 kilometres from the farm, says, "We've been made prisoners in our own homes. When the smell is bad, you can't step outside. It even stinks inside. The smell gets in your clothes."
The conflict between the mushroom farm and the residents highlights the growing tension between suburban expansion and established rural industries. As cities expand, they increasingly encroach on farmland, leading to conflicts with residents who are disturbed by the odours and operations of these farms. This issue is not unique to Ashburn, as similar battles have been fought in California, Pennsylvania, and other parts of North America.
To address the concerns, the mushroom farm owners have incurred significant costs, spending a substantial amount on legal fees and odour reduction measures. For example, they installed a system that mixes ozone with gases from the composting sheds, which has helped mitigate the odour to some extent. However, residents claim that the odour persists and continues to affect their daily lives.
The situation has led to a costly and protracted legal battle, with the farm owners defending their operations and disputing the severity of the odour's impact. While the farm owners acknowledge the presence of a smell, they believe that the issue has been exaggerated. This conflict remains unresolved, with residents continuing to seek legal recourse and farms facing the challenge of balancing their operations with the concerns of nearby residents.

Frequently asked questions
The awful smell near mushroom sheds is likely due to stinkhorn mushrooms, which emit a putrid, rotting meat-like odour to attract flies that spread their spores.
Mushroom sheds smell bad due to the presence of stinkhorn mushrooms, which thrive in the decomposing organic matter and mulch commonly found in and around mushroom farms.
To reduce the stench, you can install a system that mixes ozone with the gases emitted from the sheds. While this may not eliminate the odour entirely, it can help to make it less offensive. Additionally, removing decaying organic matter and replacing hardwood mulch with pine needles, straw, or chopped leaves can help prevent the growth of stinkhorn mushrooms.
Stinkhorn mushrooms can vary in appearance, ranging from stalk-like, globular, or latticed structures. They are often reddish-orange and may resemble a wiffle ball, an octopus, or a straight stem. In their immature "egg" stage, they are white and egg-like, growing underground or within mulch.
