Mushrooms are the reproductive structures of fungi, and while they can be a sign of healthy soil, they can also be a cause for concern, especially if you have young children or pets. Most mushrooms are harmless, but some are toxic and can cause severe illness or even death if ingested. It is therefore crucial to never consume wild mushrooms unless they have been identified by an expert. Some common poisonous varieties include Amanita, which accounts for 90% of mushroom-related deaths, and the Destroying Angel, which is also stark white in colour. On the other hand, Fairy Ring mushrooms, which often appear in circles or rings, are non-poisonous, although they don't smell pleasant.

What You'll Learn
Fairy ring mushrooms are non-poisonous but smell bad
If you've spotted white mushrooms in your pasture, it's important to identify them correctly before deciding what to do. While some mushrooms are harmless or even beneficial, others are toxic and can cause serious health issues if ingested.
One common type of mushroom that grows in pastures and yards is the false parasol, or Chlorophyllum molybdites. These mushrooms are toxic and can cause extreme digestive problems if consumed. They are commonly found in North America and are identified by their green gills and brown tissue adorning the cap and stipe.
However, there is another type of mushroom that goes by the name of "fairy ring mushroom" that is non-poisonous but may smell bad. The fairy ring mushroom, or Marasmius oreades, is native to North America and Europe and often grows in grassy areas such as lawns, meadows, and even coastal dunes. While it is considered edible, it can be easily confused with toxic species, so caution is advised. It has a tan to reddish-brown, knobbed cap with off-white gills and a bell shape that becomes broadly convex as it dries out.
Fairy rings are a result of the central area of a mycelium dying while its outer edges remain and spread outward in search of nourishment. Each year, the fairy ring grows larger, and the mushrooms that spring up within it are all part of the same organism. While fairy rings have been associated with folklore and believed to be caused by witches, devils, or fairies, they are not inherently dangerous. However, it is important to correctly identify any mushroom before consuming it, as some poisonous mushrooms can be deadly.
In summary, while the fairy ring mushroom is non-poisonous, it may have an unpleasant smell and should be identified with caution due to its resemblance to toxic species. If you are unsure about the identity of a mushroom, it is best to leave it alone or seek expert advice.

False parasols are toxic and common in North American yards
If you have white mushrooms growing in your yard, they could be false parasols, or Chlorophyllum molybdites. False parasols are toxic mushrooms that are common in yards across North America from spring to fall, especially after rain. They are also known as "vomiters" because they can cause extreme digestive problems if eaten. Although they haven't caused any known deaths, their prevalence has made them one of the most consumed poisonous mushrooms in the U.S.
False parasols are widespread and prolific, growing in meadows, lawns, and parks in great numbers across North America. They are especially common in late summer and fall and can be identified by their brown caps and green gills. They often grow in large groups or fairy rings, making them very visible and attractive to some people. They are also known as the green-spored parasol or green-gill parasol due to the distinct green shade of their gills as they mature.
False parasols are toxic to humans and animals if consumed and can cause severe gastrointestinal distress, including vomiting, diarrhea, and abdominal pain. They are often mistaken for edible mushrooms, which can lead to accidental poisoning. It is important to properly identify mushrooms before consuming them and to seek medical help if you suspect poisoning.
To avoid accidental ingestion of false parasols, it is recommended to leave mushrooms in your yard alone or remove them safely. If you are interested in foraging for edible mushrooms, it is best to consult field guides or join local amateur mycology societies to learn about proper mushroom identification. Additionally, purchasing mushrooms from a grocery store is a safer option than foraging for them in your yard or the wild.

Amanita mushrooms are poisonous and can be fatal
White mushrooms in your pasture could be Chlorophyllum molybdites, or false parasols, which are toxic and can cause severe digestive problems. They are often mistaken for edible puffballs or button mushrooms. However, there are several other types of poisonous white mushrooms, including some Amanita species.
Amanita muscaria, commonly known as the fly agaric or fly amanita, is also poisonous and can cause severe intoxication. It is a large white-gilled, white-spotted mushroom with a bright red cap. It is often mistaken for the edible Amanita caesarea, especially after heavy rain when its white spots wash away. It is used by some for its psychedelic and hallucinogenic effects, but it can be dangerous, especially in children.
Amanita bisporigera, or the destroying angel, is another toxic white Amanita species. It is similar in appearance to Amanita phalloides but does not grow in fairy rings.
If you suspect that you or someone you know has been poisoned by mushrooms, seek immediate medical attention. Do not consume wild mushrooms that have not been identified by an expert. Even washing or cooking poisonous mushrooms may not make them safe to eat.

Stinkhorns are non-poisonous but have a strong smell
If you have white mushrooms growing in your pasture, they could be Chlorophyllum molybdites, commonly known as false parasols. False parasols are toxic if consumed and can cause extreme digestive problems, although they have not caused any known deaths. They can be identified by their brown tissue and green spores.
False parasols have a deadly look-alike called the destroying angel (Amanita bisporigera), which is an uncommon species that grows on the soil in ancient woodlands associated with trees. The destroying angel is stark white with white spores and does not grow in fairy rings.
While some fungi can be harmful to ingest, many are harmless or even beneficial. For example, the Lawyer's Wig mushroom (Coprinus comatus or Shaggy Mane) is an edible mushroom commonly found in North America, Europe, and other parts of the world. It gets its name from its distinctive appearance, which resembles a shaggy, white or gray wig.
Another type of mushroom that can appear in pastures is Psilocybe, commonly known as "magic mushrooms" or "shrooms." These mushrooms grow in various habitats, including forests, pastures, and sometimes in backyard settings.
It is important to note that you cannot tell if a mushroom is poisonous without identifying the individual mushroom. Some poisonous mushrooms can be deadly, so it is best to leave them alone unless you are certain they are safe to consume. If you are concerned about mushrooms growing in your pasture, you can try to dig them out of the ground, including any mycelium, before they release spores.

Most mushrooms are harmless but some are toxic
Mushrooms are a type of fungus that has been consumed and cultivated by humans for centuries. They are a great addition to recipes and can be foraged or cultivated. However, it is important to exercise caution as not all mushrooms are edible. While most mushrooms are harmless, some are toxic and can cause serious health issues, including death.
Mushroom poisoning occurs when toxic mushrooms are ingested, often due to misidentification or accidental consumption by children or pets. Poisonous mushrooms contain various toxins, including amatoxins, orellanine, and muscarine, which can have severe and sometimes deadly effects. Symptoms of mushroom poisoning can range from mild gastrointestinal discomfort to organ failure and death. It is important to note that the period between ingestion and the onset of symptoms can vary, and serious symptoms may not appear immediately, sometimes taking days or weeks to manifest.
Some of the most lethal mushrooms include the death cap (A. phalloides), the destroying angel (A. verna), and the fool's mushroom (A. verna), all belonging to the genus Amanita. Other deadly mushrooms include the deadly webcap (C. rubellus) and the fool's webcap (C. orellanus) from the genus Cortinarius. Additionally, several species of Galerina, Lepiota, and Conocybe contain lethal amounts of toxins.
To prevent mushroom poisoning, it is crucial to properly identify mushrooms before consumption. Familiarize yourself with both edible and toxic mushroom species, especially those that resemble each other. Joining local amateur mycology societies or consulting field guides can be helpful for safer foraging. While most white mushrooms, such as fairy ring mushrooms, are considered non-poisonous, there are toxic varieties like the false parasol or Chlorophyllum molybdites, commonly found in lawns across North America. These mushrooms can cause severe gastrointestinal issues if ingested, earning them the nickname "the vomiter."

Frequently asked questions
It depends on the type of mushroom. Most white mushrooms are not poisonous, but some can be toxic and cause severe illness or even death if ingested. For example, the Amanita genus of mushrooms is poisonous and can be identified by their white colour, umbrella-shaped tops, and a cup at the base of their stems. Another poisonous mushroom is the Chlorophyllum molybdites, commonly known as the false parasol or "the vomiter", which causes severe gastrointestinal distress.
It can be very challenging to identify poisonous mushrooms as they may not look or taste dangerous. It is recommended to consult a mushroom expert or field guide before consuming any wild mushrooms. Some key features of poisonous mushrooms include gills on the underside of the mushroom caps, brown patches on the cap, and umbrella-shaped tops with a cup at the base.
If you find mushrooms in your pasture, it is important to avoid consuming them unless they have been positively identified by an expert. It is also crucial to keep children and pets away from the mushrooms to prevent accidental ingestion. While most mushrooms are harmless, it is always best to exercise caution.
