Puffball mushrooms are a unique type of fungus that grows in spherical shapes without any gills, caps, or stems. They are often large, white, and edible, making them a delightful treat for foragers and chefs alike. While they are not commonly found in grocery stores or farmers' markets, they can be found in nature, especially in well-fertilized lawns, open fields, and woods. However, cultivating puffball mushrooms is a challenging endeavour due to their complex relationship with plant roots and their low germination rate. In this article, we will explore the fascinating world of puffball mushrooms and provide a comprehensive guide on how to identify, forage, and attempt to cultivate these intriguing fungi.

Choose a location: puffball spores can grow anywhere from gardens to woods to lawns
Puffball mushrooms can grow in a variety of locations, including gardens, woods, and lawns. They are not typically found in grocery stores or farmers' markets, but they can often be discovered in nature, especially during exploration or play in wooded areas.
Puffballs are unique in that they do not bond with a particular tree, unlike other mushrooms such as chanterelles or hen of the woods, which emerge in the same spots each year. Instead, puffballs can be found in various locations, depending on where their spores have landed. They are massive spore factories, and their spores can spread out and land in different places, leading to their versatile growth habitats.
When choosing a location to cultivate puffball mushrooms, it is important to consider their ecological role and the type of organic matter they require. Most puffball mushrooms are saprobic, meaning they contribute to the decomposition of organic matter and the recycling of nutrients back into the soil. They typically grow on leaf litter, grass thatch, or other plant-based substrates like fallen leaves.
Some species, such as Lycoperdon pyriforme (Apioperdon pyriforme), are saprobic fungi that grow on and contribute to the decomposition of hardwood and conifer deadwood. They break down and feed on plant material, and their growth may be influenced by the presence of livestock manure or other high-nitrogen substrates.
While puffballs can grow in various locations, their cultivation remains challenging due to their complex relationship with plants. Puffballs, as mycorrhizal mushrooms, engage in a symbiotic relationship with plant roots, exchanging sugars for water and mineral nutrients. Recreating this intricate relationship during cultivation is extremely difficult, and successful attempts have not been published.
Despite the challenges, choosing a suitable location based on the ecological needs of puffball mushrooms can increase the chances of successful cultivation.

Prepare the substrate: fill a bucket with spring water and release spores into it
To prepare the substrate for planting puffball mushrooms, you will need to gather the necessary supplies, including a spore syringe, spawn bags, a substrate, a pressure cooker, a grow box, and a spray bottle. These items can typically be found at your local gardening or specialty food store.
Once you have the required materials, you can begin the process by preparing the spores. This involves injecting the spores into the spawn bags, where they will take root. After that, transfer the spawn bags into the pressure cooker to sterilize them.
Now, you can focus on preparing the substrate by mixing it with the spawn in a sterile environment. This step requires careful monitoring and maintenance to ensure optimal growth conditions for the mushrooms. Maintain a consistent temperature and humidity level in the grow box to promote healthy mushroom development.
While puffball mushrooms can be challenging to cultivate due to their complex growing requirements, you can increase your chances of success by creating a "spore slurry." Fill a bucket with spring water or distilled water, adding a small spoonful of molasses and a pinch of salt to enhance the mixture. Stir the contents with a clean wooden spoon until the salt dissolves.
Obtain mature puffball mushrooms that have not yet released their spores. Sanitize your hands and the surrounding area, then carefully poke a hole in the puffball. Position the hole above the bucket and squeeze the mushroom to release the spores into the water. Seal the bucket and shake it gently to distribute the spores evenly.

Inoculate the growing area: pour the mixture onto grass and keep the area misted
Puffball mushrooms are a group of mushrooms that includes several different species. They are spherical and do not have a cap, gills, or stems. Young puffballs are edible and solid white inside.
Puffballs grow anywhere that their spores have landed, unlike other mushrooms that come up in the same spots every year. They are often found in fields, deep woods, and directly on trails.
While there are no published successful cultivations of true puffballs, there are some methods you can try to grow them yourself. One method is to inoculate the growing area by pouring a mixture of spores, molasses, and salted water onto the grass and keeping the area misted. This process is detailed in the book "Growing Gourmet and Medicinal Mushrooms" by Paul Stamets.
Another method is to use a liquid culture and transfer the growing mycelium into a manure mixture or high-nitrogen substrate. You can also try cloning a fresh mushroom, which does not require germinating any spores.
It is important to note that puffball cultivation is challenging because they are mycorrhizal, meaning they often rely on their association with tree roots. Recreating this process synthetically is difficult, but creating the right conditions may lead to successful growth.

Harvesting: use a sharp knife to cut the mushrooms at the base when they are still white
When harvesting puffball mushrooms, it's important to act quickly, as they have a very short shelf life. Puffballs are best when the flesh is white, firm, and dry. The white flesh will turn yellow as the mushroom matures, and eventually, it will turn brown and black with powdery spores. Therefore, it's best to harvest puffballs when they are still white.
To harvest, use a sharp knife to cut the mushrooms at the base, where they connect to the ground. You can also gently pull them out of the ground, but using a knife is preferable if you want to preserve the mycelium so that the puffballs will continue to grow back year after year. Before cutting, check the bottom of the mushroom for any signs of larvae or worms, as insects love puffballs! If you see any bugs, cut them out right away to prevent them from infesting the rest of your harvest.
Once you've harvested your puffballs, it's best to process them for eating or freezing as soon as possible. They can start to deteriorate rapidly, and you may only have a day or two before they turn yellow and become inedible. To prepare the puffballs for eating, start by cutting through the middle of the mushroom to ensure it is white and firm inside. If it has started to turn yellow or shows any signs of gills, it is too old to eat. If the inside looks good, continue by cutting, peeling, and discarding the outermost layer of the white skin, which is rubbery and about a quarter-inch thick.
After that, you can cut the mushroom into slices of your desired thickness. Puffball mushrooms are best grilled, fried, baked, or sautéed, and they go well with a splash of lemon juice or vinegar to offset the fats. They also freeze well, lasting up to two years when stored properly. Simply brown the slices in butter on both sides, let them cool, and then stack them on wax paper before freezing in sealable bags.

Frequently asked questions
First, fill a 5-gallon bucket with 2 gallons of spring water. Then, break open a puffball mushroom over the bucket and press until spores are released. The spores will sink into the water. You can also add the mushroom pieces to the water to soak out the remaining spores. Next, pour the mixture onto a lawn, grassy field, or area where puffball mushrooms have previously grown. Mist the area every few days. Mycelium will penetrate and grow in the ground. You can expect fruiting in 3-4 weeks. Harvest the mushrooms while they are still white, using a sharp knife to cut them off at the ground.
Late August is the peak time for puffball mushrooms to grow. The growing conditions need to be right, including a wet month with plenty of rain.
Puffball mushrooms are spherical and white, without any gills, caps, or stems. They can be as small as a penny or as large as a cantaloupe.
Yes, all true puffballs are edible if they are young and completely white on the inside. If the mushroom is soft, brownish, or full of spores, it is too old to eat and may cause an upset stomach or severe poisoning.
