Puffball mushrooms are a type of fungus with a ball-shaped body that bursts on impact, releasing spores. While most puffballs are not poisonous, some look similar to toxic species, such as the death cap or destroying angel mushrooms. Puffballs are edible when young and uniformly white inside, but can become bitter as they mature and turn yellow or green. Foraging for puffballs can be dangerous as poisonous look-alikes include deadly species. Additionally, inhaling puffball spores can be harmful to both humans and dogs, and some individuals have reported allergy-like reactions to consuming puffballs.

What You'll Learn
Puffball mushrooms are edible when young, but poisonous look-alikes exist
Puffball mushrooms are a type of fungus featuring a ball-shaped fruit body that bursts on contact or impact when mature, releasing a cloud of dust-like spores. They are edible when young, but poisonous look-alikes exist, so it is important to know how to identify them.
True puffballs do not have a visible stalk or stem, whereas stalked puffballs have a stalk that supports the gleba. None of the stalked puffballs are edible as they are tough and woody mushrooms. False puffballs, which are hard like rock or brittle, are also inedible as they are bitter. The genus Scleroderma, which has a young purple gleba, should be avoided.
To identify a puffball mushroom, look for a round or pear-shaped fruit body with a small foot or stem. The surface is covered in tiny pyramid-shaped 'pearls', which when rubbed off leave a net-like pattern. The surface is white/cream when young and darkens with age, developing a darker central umbo when mature. The flesh is almost pure white and spongy when young, turning yellow/green as it matures and the spores develop. The stem is similar in colour to the fruiting body and is also covered in the 'pearls'.
To ensure that a puffball mushroom is safe to eat, cut it in half and examine the inside. The outer rind should be as thin as an eggshell; if thicker, it may be a poisonous earthball (Scleroderma sp.). The interior should be white and completely uniform. If a small mushroom shape is folded inside, it may be the 'egg' stage of a deadly species such as the death cap, Amanita phalloides, which is toxic and can cause serious illness or even death if consumed. If the inside is yellow or brown, the puffball is too old and bitter to eat.
Puffball mushrooms have a mild taste and a spongy texture, making them versatile for cooking. They can be deep-fried, grilled, or fried in butter. They can also be marinated in soy, lime juice, and ginger and then stir-fried. However, it is important to exercise caution when consuming wild mushrooms, as there is a risk of mistaking poisonous look-alikes for edible puffballs. Always cook mushrooms thoroughly before consuming them, as eating raw mushrooms can be dangerous.

Some puffball mushrooms can cause allergic reactions in humans
Puffball mushrooms are a type of fungus featuring a ball-shaped fruit body that, when mature, releases spores. While most puffballs are not poisonous, some can cause allergic reactions in humans. It is important to distinguish between true puffballs and false puffballs, as well as identify poisonous look-alikes, before consuming any puffball mushrooms.
True puffballs, such as the giant puffball (Calvatia gigantea), do not have a visible stalk or stem, while stalked puffballs like the Podaxis pistillaris have a stalk that supports the gleba, or the mass of spores. All true puffballs are edible when they are young and have undifferentiated white flesh within. However, as they mature, the flesh turns yellow or green as the spores develop, and they become bitter and unsafe to eat.
False puffballs, on the other hand, are inedible as they are tough and bitter. False puffballs include the Hymenogastrales and Enteridium lycoperdon, a slime mold, as well as all stalked puffballs. Additionally, the genus Scleroderma, which has a young purple gleba, should be avoided as it belongs to the poisonous look-alikes of puffballs, known as Earthballs.
To ensure the safety of consuming puffball mushrooms, it is crucial to properly identify them. When identifying puffballs, it is important to examine their physical characteristics. Puffballs are usually round or pear-shaped with a small foot or stem, and their surface is covered in tiny pyramid-shaped 'pearls', leaving a net-like pattern when rubbed off. The surface is white or cream when young, darkening with age, and they lack gills, pores, or spines.
While puffballs are generally considered safe for human consumption when properly identified and prepared, it is important to note that a few individuals have reported allergy-like reactions to eating them. Therefore, it is always advisable to exercise caution and consult a medical professional if any adverse reactions occur after consuming puffball mushrooms.

Puffball spores can be dangerous to dogs
Puffball mushrooms are a type of fungus featuring a ball-shaped fruit body that bursts on impact, releasing a cloud of dust-like spores. While most puffballs are not poisonous, some poisonous look-alikes include the death cap (Amanita phalloides) mushroom, which starts out as a round egg that resembles a puffball. Earthballs (Scleroderma species) also look similar to puffballs from the outside but have a thicker peridium and the internal gleba soon turns purplish-black.
Although puffballs are edible, it is important to rule out these poisonous look-alikes before consuming them. Cut puffballs in half from top to bottom and examine the cut surface. The outer rind should be as thin as an eggshell; if thicker, the fungus may be a poisonous earthball. The interior should be white and completely uniform. If a small mushroom shape is folded inside, the specimen may be the 'egg' stage of a deadly or dangerous species such as the death cap, which can cause death and serious illness if consumed.
While puffballs are generally safe for human consumption, inhaling their spores can be dangerous for dogs. In one case, a two-year-old dachshund suffered from puffball mushroom toxicosis (lycoperdonosis). Another study reported a case of inhalation pneumonitis in a dog from inhaling puffball mushroom spores. Therefore, it is important to be cautious and prevent dogs from inhaling puffball spores, as they can be harmful to their health.
To identify a puffball mushroom, look for a round or pear-shaped fruit body with a small foot or stem. The surface is usually white or cream-colored when young, darkening with age, and will have a darker central umbo when mature. The flesh is white and spongy when young, turning yellow or green as the spores develop. The stem is similar in color to the fruit body and is covered in tiny pyramid-shaped 'pearls', which leave a net-like pattern when rubbed off.

Puffball mushrooms are toxic when old and bitter
Puffball mushrooms are a type of fungus featuring a ball-shaped fruit body that, when mature, releases spores. While most puffballs are not poisonous, some poisonous look-alikes include the death cap (Amanita phalloides) mushroom, which starts out as a round egg that resembles a puffball. Puffballs are edible when they are young and uniformly white inside. However, they become bitter and toxic when old, with a yellow or brown interior.
Puffballs can be identified by their ball to pear-shaped fruit bodies, sometimes with a base like an inverted cone. They lack gills, pores, or spines and can be found growing in woodlands or grass. The surface of the fruit body is covered in tiny pyramid-shaped 'pearls', which when rubbed off leave a net-like pattern. The surface is white or cream when young, darkening with age, and will develop a darker central umbo when mature. The flesh is white and spongy when young, turning yellow or green as it matures and the spores develop.
It is important to properly identify puffball mushrooms before consuming them, as some poisonous mushrooms resemble puffballs. To identify a puffball mushroom, cut it in half and examine the inside. The outer rind should be as thin as an eggshell; if thicker, it may be a poisonous earthball (Scleroderma sp.). The interior should be white and uniform. If a small mushroom shape is folded inside, it may be the 'egg' stage of a deadly species such as the death cap. If the inside is yellow or brown, the puffball is too old and bitter to eat and may be toxic.
In addition to the risk of poisoning from consuming old and bitter puffballs, inhaling puffball spores can also be dangerous. While the disease is rare, it is possible to develop lycoperdonosis, or "Wolf Fart Disease", from inhaling a large quantity of spores. Dogs are particularly susceptible to suffering adverse effects from inhaling puffball spores.

Some puffball mushrooms are inedible due to their woody texture
While puffball mushrooms are generally edible and not poisonous, caution must be exercised as some puffball mushrooms are inedible due to their woody texture. It is important to properly identify puffball mushrooms before consumption to avoid ingesting toxic varieties.
True puffballs do not have a visible stalk or stem, while stalked puffballs possess a stalk that supports the gleba, or the mass of spores. None of the stalked puffballs are edible as they are tough and woody. False puffballs, which are hard and brittle, are also inedible due to their bitter taste.
To ensure the edibility of a puffball mushroom, it is crucial to examine its internal characteristics. Cut the puffball in half and inspect the inner flesh. Safe-to-eat puffballs have a uniformly white interior. If the inside is yellow or brown, the mushroom is too old and bitter for consumption. Additionally, if a small mushroom shape is present within, it may be the 'egg' stage of a dangerous species, such as the death cap, which is toxic.
Puffball mushrooms are versatile in culinary preparations. They can be deep-fried after dipping in flour, egg, and breadcrumbs, grilled, or fried in butter. Their spongy texture allows them to absorb other flavours effectively, making them suitable for stir-frying with various marinades.
It is worth noting that some individuals have reported allergy-like reactions to consuming puffballs. Additionally, inhaling puffball spores can be dangerous, potentially causing lung irritation and other respiratory issues. Therefore, it is advisable to wear a face covering when handling dried puffballs to prevent spore inhalation.
