Stinkhorn mushrooms are known for their distinctive appearance and foul odour, which is said to resemble decomposing flesh, rotting faeces, and sewage. Despite their unpleasant smell, they are not poisonous to humans and are even considered a delicacy in some cultures. Stinkhorns are saprophytic fungi, feeding on dead and decomposing plant material. They play an important role in ecosystems by contributing to the recycling of plant debris and improving soil fertility. The odour of stinkhorn mushrooms serves a purpose in attracting insects, which then spread the mushroom's spores to new locations. While not poisonous, there have been reports of dogs experiencing gastric irritation after ingesting stinkhorn mushrooms.

What You'll Learn
Stinkhorn mushrooms are not poisonous to humans
Stinkhorn mushrooms are characterised by their unpleasant odour, which has been described as similar to decomposing flesh, rotting faeces, and sewage. This foul smell is due to the presence of volatile compounds, such as dimethyl sulphides, within the slimy exudate or gleba. Despite their repulsive odour, stinkhorn mushrooms are not toxic to humans. No human fatalities have been recorded as a result of consuming these fungi.
However, it is important to note that stinkhorn mushrooms can cause gastric irritation in dogs, according to anecdotal veterinary evidence. Therefore, while stinkhorn mushrooms are not poisonous to humans, it is always advisable to exercise caution when consuming any type of mushroom, as some species may be toxic or have adverse effects.
Stinkhorn mushrooms are unique in their method of spore dispersal. Unlike typical mushrooms that rely on wind to disperse their spores, stinkhorns use insects. The odorous chemicals in the gleba, such as methanethiol, hydrogen sulfide, and linalool, attract flies and other insects, which then feed on the sticky spore mass on the tip of the mushroom. This ecological interaction between invertebrates and stinkhorns is beneficial for both parties, as the invertebrates receive a food source, and the stinkhorns utilise the insects for effective spore dispersal.
Stinkhorn mushrooms are saprophytic fungi, meaning they feed on dead and decomposing plant material. They are commonly found in gardens, on wood or bark-chip mulch, and on deep litter on the rainforest floor. They contribute to the recycling of plant debris, improving soil fertility and providing beneficial nutrients for garden plants. While they may be unwanted additions to home gardens due to their unsightly appearance and putrid smell, stinkhorn mushrooms do not cause plant disease and have a short life cycle.

They are considered toxic to dogs, causing gastric irritation
Stinkhorn mushrooms are considered toxic to dogs, causing gastric irritation. While stinkhorn mushrooms are not listed as toxic to humans, they have been reported to cause gastric irritation in dogs. The foul-smelling spore mass of these fungi is enough to tempt even the fussiest of dogs. The smelly liquid portion of the mushroom can cause digestive upset in dogs, leading to vomiting and diarrhea. In some cases, dogs have also shown signs of lethargy and bloody mucousy stools after ingesting stinkhorn mushrooms.
Stinkhorn mushrooms are not considered toxic to humans, and some cultures even consume them in their early stages of development, when they are said to have a hazelnut-like flavor. However, they can be dangerous to dogs and cause a range of symptoms, including gastroenteritis-like syndrome. While many cases of mushroom ingestion may result in no symptoms at all, it is important to remain cautious and seek veterinary advice if your dog has ingested a wild mushroom.
The recent wet weather in eastern Australia has driven the growth of stinkhorn fungi, leading to multiple dog fatalities in Queensland and northern New South Wales. The rotting meat smell of these fungi is highly attractive to dogs, and there is currently no antidote to the toxin. Therefore, it is crucial for pet owners to be vigilant and take preventive measures to protect their dogs from ingesting stinkhorn mushrooms. Keeping dogs on a leash while in parks or removing any wild mushrooms from yards before dogs have access to them can help reduce the risk of ingestion.
If you suspect your dog has ingested a stinkhorn mushroom, it is important to act quickly. Inducing vomiting within 30-60 minutes of ingestion may help to reduce the amount of toxin absorbed by your dog's body. Additionally, seeking early treatment from a veterinarian is crucial to your dog's survival, as they can provide treatment to make your dog bring up the fungi before it causes serious health issues.

Stinkhorns attract insects with their putrid smell to spread spores
Stinkhorn mushrooms are renowned for their putrid smell, which has been likened to decomposing flesh, rotting faeces, sewage, and carrion. This foul odour is caused by a host of volatile compounds within the slimy exudate or gleba, including dimethyl sulphides, linalool, and trans-ocimene. Despite their unpleasant smell, stinkhorns are not poisonous to humans and are even considered a delicacy in some cultures.
Stinkhorns, unlike typical mushrooms, do not release their spores into the wind for dispersal. Instead, they attract insects and other invertebrates with their putrid smell. The odorous chemicals in the gleba, such as methanethiol, hydrogen sulfide, and dimethyl trisulfide, are detected by the invertebrates, 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 invertebrates' bodies.
Flies are particularly attracted to the stinkhorns' scent, and after feeding on the slimy spore mass, they fly off and dispense the spores wherever they land. Other insects attracted to the stinkhorns include blow-flies, slugs, and carrion insects, especially of the family Sarcophagaceae. This process of using insects for spore dispersal is comparable to the distribution of pollen by bees as they forage on multiple flowers.
The role of invertebrates in stinkhorn reproduction is essential for the spread and maintenance of genetic diversity as they move from one mushroom to the next. However, the ecological interactions between invertebrates and stinkhorns are not yet fully understood and require further study.

They are found in mulch, lawns, and bare soil
Stinkhorn mushrooms are not considered poisonous to humans. They are commonly found in mulch, lawns, and bare soil. They are introduced into a garden in organic materials, such as soils and mulches, that contain microscopic hyphae (fungal threads) of stinkhorn fungi. They are also found in deep litter on the rainforest floor.
Stinkhorn mushrooms are often first discovered in gardens, sprouting from an egg-like bulb with orange or red stalks. They produce a slimy, foul-smelling spore coating near the tip, which attracts flies and other insects. The smell has been described as similar to decomposing flesh, rotting faeces, sewage, or rotten meat. The colour of the stalks can vary, with most being white, red, or pink.
Stinkhorn mushrooms are considered noxious for their unpleasant odour and have been reported to cause gastric irritation in dogs. They are not toxic to humans, and there have been no recorded human fatalities resulting from their consumption. However, they are often unwanted in home gardens due to their unsightly appearance and putrid smell.
Stinkhorn mushrooms can be removed from gardens by plucking them out of the ground. However, it is important to note that removing the mushrooms will not eradicate them, as the hyphae will remain in the soil or mulch and will eventually produce new stinkhorn mushrooms.

Stinkhorns are eaten in salads, soups, sausages, and as a preservative
Stinkhorn mushrooms are not poisonous and are edible. They are often consumed in their immature "egg" stage, which is said to have a hazelnut flavour. The common stinkhorn, Phallus impudicus, is known to have a hazelnut flavour when eaten in its egg stage. Despite their unpleasant odour, stinkhorns are used in a variety of dishes, including salads, soups, sausages, and pickled items. They also serve as a short-term preservative.
Stinkhorn mushrooms are known for their distinctive odour, which has been described as similar to decomposing flesh, rotting faeces, sewage, or carrion. This odour is caused by volatile compounds, including dimethyl sulphides, linalool, and trans-ocimene. The smell attracts insects, such as flies, slugs, and carrion insects, which feed on the spore mass and help disperse the spores to new locations.
Stinkhorns are considered a delicacy in China, where they are commercially grown and used in various recipes. They are also known to attract dogs, which may experience gastric irritation if they ingest the mushrooms. While stinkhorns are not toxic to humans, they can cause gastric irritation in dogs and nervous system impairment.
Stinkhorn mushrooms are unique in their appearance, often resembling horns or penises, with some species having multiple appendages that give them an octopus-like or squid-like look. They are found in various colours, including white, tan, green, orange, red, and black. Stinkhorns typically grow on decaying wood or plant material and contribute to recycling plant debris into nutrients that improve soil fertility.
Stinkhorn mushrooms are often unwelcome in gardens due to their unpleasant odour and unsightly appearance. However, they do not cause plant disease and are short-lived, typically shrivelling up a day or two after their rapid growth spurt. Gardeners can reduce the number of stinkhorns by removing organic matter, such as mulch, or reducing soil moisture.
