Mushrooms are a type of fungus that can be found in various shapes, sizes, and colours. While some mushrooms are safe to consume and even offer health benefits, others can be extremely dangerous and even life-threatening. One such danger is the release of mushroom dust, which is a cloud of spores that can be released when a mature mushroom is disturbed or naturally deteriorates. Inhaling large amounts of these spores can lead to a rare respiratory disease called Lycoperdonosis, which is characterised by symptoms such as nausea, rapid pulse, and difficulty breathing. Therefore, it is important to be cautious when handling or interacting with mushrooms to avoid potential health risks associated with mushroom dust inhalation.

What You'll Learn
Inhaling mushroom dust can cause lycoperdonosis, a respiratory disease
Inhaling mushroom dust can be dangerous, as it may cause lycoperdonosis, a respiratory disease. Lycoperdonosis is an inflammation of the alveoli within the lung caused by inhaling natural dusts, specifically spores from mature puffball mushrooms. Puffballs are a type of fungus featuring a ball-shaped fruit body that bursts on contact or impact, releasing a cloud of dust-like spores. These spores can cause respiratory issues if inhaled in large quantities.
The disease typically progresses with symptoms similar to a cold, such as cough, fever, and shortness of breath, followed by nausea, rapid pulse, and dyspnea. In severe cases, individuals may require hospitalization and even intubation to assist in breathing. The disease is rare, as a large number of spores need to be inhaled for clinical effects to occur. However, it is important to be cautious and seek medical attention if you experience any of these symptoms after inhaling mushroom dust.
The giant puffball, Calvatia gigantea, is a notable example of a puffball mushroom that produces an estimated 7 x 10^12 spores when mature, more than any other known organism. It is important to be cautious around such mushrooms and avoid inhaling their spores. While most puffballs are not poisonous, some may resemble toxic varieties, such as the deadly Amanitas, so proper identification is crucial before consumption or handling.
It is worth noting that Lycoperdon species have been used in folk medicine for their believed haemostatic properties. However, inhaling the spores in large quantities can lead to severe respiratory issues, as evidenced by several reported cases of teenagers experiencing severe symptoms, including coma, liver damage, and the need for life support. Therefore, it is crucial to approach wild mushrooms with caution and avoid inhaling any mushroom dust to prevent the risk of lycoperdonosis.

Puffballs are a type of fungus that releases dust-like spores
Puffballs are a unique group of mushrooms that do not expose their gills and forcibly expel spores into the wind. Instead, they rely on external forces to release and disperse their spores. Puffballs are spherical, ball-shaped, or pear-shaped mushrooms that house a mass of dust-like spores inside. They are part of the division Basidiomycota and encompass several genera, including Calvatia, Calbovista, and Lycoperdon.
The distinguishing feature of puffballs is their method of spore production. Unlike other mushrooms, puffballs produce spores internally in a spherical fruiting body called a basidiocarp. The spores mature within a pliable, spherical sac called the peridium, which is entirely enclosed except for a small hole at the top through which the spores are released. This release occurs when the mature puffball bursts upon contact or impact, dispersing a cloud of dust-like spores into the surrounding area.
The most common way puffballs release their spores is through the impact of raindrops or small animals bumping into the peridium. When disturbed in this way, the spores are ejected en masse, creating a puff of smoke-like cloud. This method of spore dispersal is quite passive, as the energy needed to eject the spores is supplied by external forces, with the puffball simply needing to be present.
While puffballs are fascinating to observe and interact with, caution should be exercised to avoid inhaling the spores. Inhaling large amounts of spores from mature puffballs can lead to lycoperdonosis, a respiratory disease classified as a type of hypersensitivity pneumonitis. Symptoms can include cold-like symptoms, nausea, rapid pulse, and dyspnea. In severe cases, individuals may require hospitalization and even intubation to assist with breathing. Therefore, while puffballs are intriguing, it is important to maintain a safe distance and avoid inhaling their spores.

Some puffballs resemble toxic Amanita mushrooms
Puffball mushrooms are edible fungi that are commonly found in many meadows and forests. However, some toxic Amanita mushrooms closely resemble edible puffballs. These poisonous fungi include the young destroying angel and death cap mushrooms. Amanita verna, also known as the Fool's Mushroom or Spring Amanita, is another toxic look-alike that is responsible for numerous poisoning cases each year, with a high fatality rate of up to 50%.
Amanita mushrooms are distinguished by their white oval shape in their early growth stages, resembling the "button" or "egg" form of puffballs. However, when you pluck young Amanitas, you will notice a stout stem encased in a volva, a trait absent in puffballs. To differentiate between the two, it is recommended to slice the mushroom vertically from the top of the cap to the bottom. Edible puffballs should have pure white flesh, resembling marshmallows or fresh mozzarella, while Amanita species will reveal the future stem and cap in cross-section.
The toxic Amanita species can lead to fatal foraging accidents, with symptoms including nausea, vomiting, abdominal pain, diarrhoea, and other gastrointestinal issues. Inhalation of Amanita spores can also result in lycoperdonosis, a respiratory disease characterised by symptoms similar to a cold, followed by nausea, rapid pulse, and difficulty breathing. Therefore, it is crucial to correctly identify mushrooms before consumption and exercise caution when foraging in the wild.
While puffball mushrooms themselves are not lethal, overzealous dogs inhaling large amounts of their spores have been reported to suffer fatal consequences. Additionally, some people may experience rare allergic reactions to puffballs, further emphasising the importance of consuming new foods in small portions initially.

Lycoperdon species are used in folk medicine
Mushroom dust is dangerous when inhaled in large quantities. This is because mushroom spores are associated with a respiratory disease called lycoperdonosis, which is a type of hypersensitivity pneumonitis. It is an inflammation of the alveoli within the lungs caused by hypersensitivity to inhaled natural dusts. The symptoms of lycoperdonosis include a cough, fever, shortness of breath, myalgia, fatigue, nausea, rapid pulse, crepitant rales, and dyspnea.
Despite the dangers of mushroom dust, Lycoperdon species, such as Lycoperdon perlatum, have been used in folk medicine. Lycoperdon perlatum, also known as the common puffball, is considered a good edible mushroom when young. The fruit bodies can be sliced and fried in batter or egg and breadcrumbs, or used in soups as a substitute for dumplings. However, as it matures, it becomes inedible as the gleba turns yellow and then develops into a mass of powdery olive-green spores.
The spores of Lycoperdon species have been traditionally believed to possess haemostatic properties, that is, the ability to stop bleeding. This belief has led to several instances of teenagers inhaling the spores, resulting in severe cases of lycoperdonosis. In one case, an individual inhaled a large amount of spores and had to be placed on life support before recovering in about four weeks. In another instance, a teenager spent 18 days in a coma, underwent lung and liver surgery, and suffered severe liver damage.
The use of Lycoperdon species in folk medicine highlights the potential dangers of misusing natural substances. While some may believe in the medicinal properties of certain mushrooms, inhaling mushroom spores can lead to severe respiratory issues and even life-threatening situations. It is crucial to exercise caution and seek proper medical advice before consuming or inhaling any type of mushroom or spore.

Lycoperdonosis is a respiratory disease caused by inhaling spores from mature puffballs. It is a type of hypersensitivity pneumonitis, resulting in inflammation of the alveoli within the lungs. Typical symptoms include cold-like symptoms, nausea, rapid pulse, and dyspnea. In one case, an individual who inhaled a large amount of spores required life support and took about four weeks to recover. In another instance, a teenager who spent 18 days in a coma suffered severe liver damage and had portions of his lung removed.
Puffballs are a type of fungus that feature a ball-shaped fruit body. When mature, they burst on impact, releasing a cloud of dust-like spores. While most puffballs are not poisonous, some may resemble toxic young agarics or deadly Amanitas, such as the death cap or destroying angel mushrooms. Therefore, it is important to properly identify mushrooms before handling or consuming them.
Stump puffballs, or Lycoperdon pyriforme, are a type of mushroom that grows on decaying tree stumps in large clusters. In the fall and early winter, they transform into hollow, spore-filled air sacs. The spores are released naturally by forces like rain or animals. However, they can also be released when the mushrooms are disturbed by humans.
It is important to be cautious when encountering mushrooms and their spores. While liver damage from inhaling spores is rare, it is a serious condition. To prevent potential health risks, it is advisable to avoid inhaling mushroom spores and to seek medical attention if you experience any adverse symptoms after exposure.
