Puffball mushrooms are a unique type of fungus that encompasses several genera, including Calvatia, Calbovista, and Lycoperdon. They are characterized by their ball-shaped fruit bodies, which, upon maturity, burst on impact or contact, releasing a cloud of dust-like spores. Puffballs are saprobic, meaning they decompose dead organic matter to grow, and can be found in open areas such as fields, roads, and grassy forest clearings. They are also known for their medicinal properties, including antibacterial, antifungal, and antimicrobial effects. While most puffballs are edible when young and pure white inside, it is crucial to distinguish them from false puffballs and look-alikes, as consuming mature puffballs can lead to adverse reactions.

What You'll Learn

Puffball mushrooms are a type of fungus
Puffballs are unique in appearance compared to other types of mushrooms, lacking the typical cap and stem. Instead, they are spherical and have a distinct colour and texture. The spores are produced internally in a spheroidal fruit body called a gasterothecium (gasteroid 'stomach-like' basidiocarp). As the spores mature, they form a mass called a gleba in the centre of the fruit body. The basidiocarp remains closed until after the spores have been released.
Puffballs cover a wide number of species throughout North America, and most come into maturity in late summer or autumn. They range in size from a golf ball to a beach ball, with the Giant Puffball (Calvatia gigantean) being a highly prized find by wild food foragers. Puffballs are saprobic, meaning they decompose dead organic matter to grow, and they can be found in open areas such as fields, roads, trails, and grassy clearings in forests.
Puffballs are also known for their edibility and medicinal properties. Young puffballs are edible and have a white, spongy flesh. As they mature, the flesh turns yellow or brown and becomes unsafe to eat. Puffball spores have been found to possess antibacterial, antifungal, and antimicrobial properties, effective in fighting various bacteria and infections.
Puffballs have been used traditionally in various ways, such as by the Blackfoot Native American Indian tribe, who used dried puffballs as a reliable tinder for fire. In Tibet, puffballs were burned and used to make ink, and they were also believed to ward off ghosts and evil spirits.

They are edible if pure white inside
Puffball mushrooms are a type of fungus featuring a ball-shaped fruit body that, when mature, releases spores in a cloud of dust. They are saprobic, meaning they decompose dead organic matter to grow, and are therefore often found in open areas such as fields, roads, trails, and grassy forest clearings.
Puffballs are a fantastic wild edible, but they have several deadly look-alikes, so it is important to know how to identify them. Firstly, true puffballs do not have a visible stalk or stem, whereas false puffballs, which are inedible, do. Secondly, puffballs should be perfectly white inside. If they are at all yellow or greenish, they are too old to eat. This rule is universally accepted in the foraging world and will keep you safe.
It is also important to inspect the root base of the mushroom for larvae and cut away any infested portions. If you are unable to source your own local supply, you can buy spores for edible puffballs online.
Puffballs have a mild, earthy flavour and a familiar texture. They can be used in endless recipes in place of shop-bought mushrooms and can even replace aubergine or be used as a meat alternative. They can be dehydrated, frozen, or cooked in a variety of ways, including breading and frying, sautéing, and stir-frying.

They can be poisonous if mistaken for Amanita mushrooms
While most puffballs are not poisonous, they can sometimes look similar to young agarics, especially the deadly Amanita mushrooms. Amanita mushrooms, also known as death caps or destroying angel mushrooms, can be very toxic.
Puffballs are generally considered edible and are placed by wild food harvesters among the "Foolproof Four" of edible fungi. However, some dangerous fungi can resemble puffballs in their early growth stage, known as the "'button' or 'egg' stage". These dangerous fungi include poisonous Amanita mushrooms, which can be identified by their gills when sliced open, as opposed to the pure white flesh of common puffballs.
It is important to distinguish between true puffballs and false puffballs, as none of the stalked or false puffballs are edible. False puffballs, such as Hymenogastrales and Enteridium lycoperdon, are hard, bitter, and inedible. True puffballs, on the other hand, do not have a visible stalk or stem, and have a powdery gleba when mature.
To ensure the edibility of a puffball, it is recommended to slice it in half and examine the interior. The outer rind should be thin, and the interior should be pure white and uniform, resembling marshmallow or fresh mozzarella. If a small mushroom shape is visible inside, it may be the "egg" stage of a deadly Amanita mushroom, and it should be avoided.
Additionally, it is important to inspect the root base of the puffball for any larvae and to cut away any infested portions. The presence of green or yellow colouring may indicate that the puffball is too old and bitter for consumption.

They grow anywhere their spores land
Puffballs are a unique type of fungus, with a ball-shaped fruit body that bursts on contact or impact when mature, releasing a cloud of dust-like spores into the surrounding area. They get their name from this distinctive feature.
Puffballs grow anywhere that their spores have landed, unlike other mushrooms that grow in the same spots year after year. They are not parasitic and do not bond with particular trees, but rather decompose dead organic matter, such as leaf litter, to grow.
Puffballs can be found in fields, forests, and along roads and trails. They are often discovered in rings, which some people call "fairy circles". They are usually found in late summer or fall.
While most puffballs are not poisonous, it is important to identify them correctly as some poisonous mushrooms resemble puffballs in their early growth stage. True puffballs are solid white inside, and all true puffballs are edible if picked young enough. As they mature, the interior turns yellow, green, or brown, and they are no longer safe to eat.
Puffballs have been used for various purposes throughout history, including as a natural remedy for burns and to stop bleeding. They have also been used to make ink in Tibet and as a natural anaesthetic for honey collection by rural Americans.

They have medicinal and antibacterial properties
Puffball mushrooms are a type of fungus with a ball-shaped body that bursts on impact, releasing a cloud of dust-like spores. They are not parasitic but rather decompose dead organic matter to grow. They are found in open areas such as fields, roads, trails, and grassy clearings in forests.
Puffballs have been used for various purposes throughout history. Some Native American tribes wore dried puffballs around their necks to ward off ghosts and evil spirits. The Blackfoot Native American tribe, for instance, believed that puffballs were stars that had fallen to the Earth during a supernatural event. They also used dried puffballs as a reliable tinder to start fires.
Puffballs have also been used for medicinal purposes. The spores of puffballs have been found to possess antibacterial, antifungal, and antimicrobial properties. They can fight harmful bacteria such as E. coli, Salmonella typhimurium, and Staphylococcus aureus (the cause of staph infections). The Cherokee Indians used puffballs to help heal sores and burns, and the Lakota tribe used dried puffball spores to treat bleeding, promote blood clotting, and heal wounds.
In addition to their medicinal properties, puffballs are also edible and highly prized by wild food foragers. When young, puffballs have undifferentiated white flesh, whereas the gills of immature poisonous mushrooms can be seen upon close examination. Before consuming puffballs, it is important to inspect the root base for larvae and ensure that the flesh is pure white. They can be dehydrated, frozen, or cooked in various recipes such as stir-fries.
Puffballs also have antioxidant properties and can help prevent oxidative damage and protect the body from illnesses. They contain bioactive compounds such as beta-sitosterol and melanin, which promote anti-inflammatory effects and help regulate the immune system.

Frequently asked questions
Puffballs are a unique type of fungus that encompasses several genera, including Calvatia, Calbovista, and Lycoperdon. They are spherical and don't have the typical cap and stem of most mushrooms.
Puffballs grow in open areas such as fields, roads, trails, and grassy clearings in forests. They are commonly found in late summer or fall. Unlike other mushrooms, puffballs grow where their spores land, so they can appear in different spots each year.
Yes, most puffballs are edible when young and have pure white flesh. However, it's important to correctly identify them as some poisonous mushrooms resemble puffballs. Always cook them before consuming.
Puffballs reproduce by releasing clouds of spores when they mature and burst or are disturbed. These spores then spread and grow into new puffballs. Each puffball can release billions of spores, but only a fraction of them grow into mature fungi.
