Puffball mushrooms are rare in southeast US regions
Puffball mushrooms are a unique type of fungus, with a ball-shaped fruit body and no visible stalk or stem. They are often spherical and white, and can be distinguished from other mushrooms by their pure white insides, with no gills or markings. They are usually found in meadows, fields, and deciduous forests, and are common in many parts of the world, including the United Kingdom and North America.
However, puffball mushrooms are notably rare in the southeast regions of the United States. While they are widespread throughout the rest of the country, they are less commonly found in these southern states. This rarity may be due to a variety of factors, such as climate, soil type, or other environmental conditions that are less favourable for the growth of puffball mushrooms in this specific region.
Puffballs are well-known to Native American tribes across North America, who have traditionally used them for various purposes. Some tribes, such as the Cherokee Indians, used puffballs to help heal sores and burns, while others wore dried puffballs around their necks to ward off evil spirits. Despite their traditional uses, it is important to exercise caution when consuming puffball mushrooms, as they have some extremely poisonous look-alikes, including young destroying angel and death cap mushrooms.
Foragers and mushroom enthusiasts often seek out puffball mushrooms for their culinary and medicinal properties. They are considered a wild edible, with a mild, earthy flavour, and can be used in various recipes, such as stir-fries and burgers. However, it is crucial to correctly identify puffball mushrooms before consuming them, as only young puffballs with pure white flesh are safe to eat. As they mature, the flesh turns yellowish or greenish-brown, indicating the presence of spores, which can cause digestive issues.
Puffballs are also known for their unique reproductive mechanism. They are massive spore factories, producing billions of spores that are released into the wind or when disturbed by raindrops, forming a cloud of spores that can spread and grow into new puffballs. This characteristic makes them fascinating to observe in nature, and their ability to decompose organic matter contributes to the ecological balance of their habitats.

They are edible and have medicinal uses
Puffball mushrooms are not only fascinating in their unique structure and life cycle but also offer culinary and medicinal value. While some species are indeed rare, others are more common and have been used by humans for centuries. Regarding edibility, not all puffball mushrooms are safe to consume, but several species are considered delicious and nutritious treats.
The most well-known and widely consumed puffball variety is the Giant Puffball (Calvatia gigantea). This species can grow to impressive sizes, sometimes reaching diameters of up to 15 inches (38 cm) and weighing several pounds. When young, the interior of the Giant Puffball is firm and white, making it ideal for eating. It has a mild flavor and a texture similar to tofu or egg custard, absorbing the flavors of accompanying ingredients in cooked dishes.
To ensure safety, proper identification is crucial, as immature puffballs can be mistaken for immature button mushrooms or other toxic look-alikes. When identifying edible puffballs, it's important to ensure the interior is completely white and firm, and the exterior is smooth and unblemished. As the mushroom matures, the flesh turns yellow-green and develops a strong, unpleasant odor, indicating that it is no longer safe to eat.
In addition to their culinary uses, puffball mushrooms have a long history of medicinal applications. Various cultures have utilized these fungi to treat wounds, stop bleeding, and address various health concerns. For example, the Giant Puffball has been used topically to treat skin irritations and infections, and its astringent properties have been employed to help contract tissues and reduce bleeding from minor cuts and scrapes.
Puffball mushrooms are also known for their potential immune-boosting properties. The presence of complex carbohydrates, known as beta-glucans, in these fungi is thought to stimulate the immune system and enhance its response to foreign invaders. Additionally, puffballs contain antioxidants that can help protect the body from the damaging effects of free radicals, thereby reducing the risk of chronic diseases and promoting overall health.
While puffball mushrooms offer these potential benefits, it is always important to exercise caution and properly identify the species before consumption, as some similar-looking mushrooms can be toxic. Additionally, as with any wild mushroom, it is advisable to consume only a small amount initially to ensure no allergic reactions or sensitivities occur.

They are not parasites
Puffball mushrooms are not parasites. They are saprobic, meaning they decompose dead organic matter in order to grow. They are often found in fields, meadows, and forests, and are characterised by their spherical shape and lack of a typical mushroom cap and stem. Instead, they produce spores internally in a structure called a gleba, which is located in the centre of the fruit body. When the puffballs mature, the gleba may turn yellow or green, indicating that they are no longer edible.
Puffballs are part of the Basidiomycota division and encompass several genera, including Calvatia, Calbovista, and Lycoperdon. They are known for their unique appearance and can be easily identified by their solid white interior. Young puffballs that are pure white inside and out are edible, with a mild, earthy flavour. However, it is important to distinguish them from poisonous look-alikes, such as the death cap and destroying angel mushrooms.
Unlike parasitic mushrooms, puffballs do not depend on a host organism for their survival. They obtain their nutrients from decomposing organic matter, making them an important part of the ecosystem. While they are not parasites, some people may consider them a nuisance when they appear in lawns or gardens. However, for those interested in foraging, puffballs can be a rewarding find.
The Giant Puffball (Calvatia gigantea) is one of the most well-known species, growing up to one foot in diameter. It is commonly found in meadows, fields, and forests during late summer and autumn in temperate regions worldwide. Other species, such as the Warted Puffball (Lycoperdon pyriforme), are also sought after by foragers but are only edible when young, before the caps turn brown.
In summary, puffball mushrooms are not parasites but rather saprobic fungi that play a vital role in decomposing organic matter. They are valued for their edibility, unique appearance, and cultural significance, with some Native American tribes using them for medicinal and spiritual purposes. However, it is crucial to accurately identify puffballs before consumption due to the presence of poisonous look-alikes.

They are used to make ink
Puffball mushrooms are not rare. They cover a wide number of species throughout North America and are usually found in fields, by roads and trails, and in grassy clearings in the forest. They are usually found in late summer or fall.
Puffballs are also used to make ink. One source details how a girl found a puffball mushroom in a bog, and she and the narrator decided to make ink from it, inspired by monks in the abbeys who would do the same. They soaked the mushroom with cloves for a few days and then simmered it to reduce the liquid.
Another source details how to make ink from the Inky Cap mushroom (Coprinopsis atramentaria). The author harvested six of the most degraded Inky Caps and put them into a glass jar to sit for about a week. Each day, they checked on the mushrooms to see what was happening. Over time, the whitish-gray parts of the mushroom transformed into a black, almost oily liquid. The author strained the ink solution through a fine-mesh filter into another jar and used it with their turkey quill pens, bamboo and reed pens, and paintbrushes.
A third source provides instructions on how to make ink from Shaggy Mane Inky Caps. You need to pick 6 to 12 Shaggy Mane mushrooms and place them in a container. After about 12 hours, you can start straining the mushrooms for ink. If you don't want to strain them, it takes about two weeks for the mushrooms to dissolve into ink. The author adds that the decaying mushrooms start to smell after several days, so they add a couple of drops of Melaleuca essential oil, thyme oil, or oregano oil to eliminate the smell.

They are not poisonous but have poisonous look-alikes
Puffball mushrooms are a fantastic wild edible but they have several deadly look-alikes. The interior of an immature puffball is white, while that of a mature specimen is greenish brown. The fruiting body of a puffball mushroom develops within a few weeks and soon begins to decompose and rot (at which point it is dangerous to eat).
The best way to check if you have a puffball is to cut the mushroom in half from the top of the cap to the bottom. The inside of edible puffball mushrooms should be solid and pure white, like a marshmallow, or fresh mozzarella balls. There should be no patterning, marks or colors inside, or anything other than pure white, and especially no signs of gills. If there are any gills present, then it isn’t a puffball mushroom.
Some poisonous mushrooms that resemble puffballs include the Destroying Angel and other Amanita species like the Death Cap Mushroom. This is because of their white oval shape in their egg stages. However, when you pluck young Amanitas from the ground, you will notice a stout stem encased in a volva—a trait absent in puffballs.
The Pigskin Poison Puffball, or Scleroderma citrinum, is also a poisonous look-alike. It is distinguished by its small size and dark purple to black interior, even when young and firm. However, true puffballs are always pure white inside.
Honey mushrooms, or Armillaria mellea, are another group of fungi that can resemble puffballs. False Parasol mushrooms also look similar to edible True Parasol mushrooms, but toxic C. molybdites have a shorter stem and wider cap.
