What You'll Learn

How to identify 29 edible mushrooms
Identifying edible mushrooms can be tricky, and it's important to be cautious as some poisonous mushrooms can be deadly. There are some rules of thumb to follow, but the only way to be 100% sure is to be able to identify the individual mushroom species.
One way to learn about edible mushrooms is to consult a field guide for your region, which can help you become familiar with common edible and poisonous varieties. You can also take mycology classes at a local university, or connect with a mushroom expert through a local mycological group.
There are some general rules for picking safe mushrooms, but it's important to note that these are not always reliable. For example, it is easy to peel the cap of a Death Cap mushroom, and some safe mushrooms grow on wood, but this is also true of some deadly varieties, such as the Funeral Bell. It is also not true that mushrooms are safe to eat if you see other animals consuming them. However, there are some rules that can help you avoid poisonous mushrooms, such as avoiding those with white gills, a skirt or ring on the stem, and a bulbous or sack-like base called a volva. These characteristics will help you avoid the deadly Amanita family of mushrooms.
Some common edible mushrooms include:
- Chanterelles, which have a gold-yellowish or brilliant orange colour, making them easy to spot.
- Morels, which have an iconic honeycomb-looking or corrugated-type cap that grows above a white stem. They are hollow from the cap through the stem when cut open. They grow in almost every state except Florida and Arizona, which are too hot and arid.
- Hericium erinaceus, also known as the bearded tooth, hedgehog, or pompom mushroom. It has a distinctive shape that resembles a male lion's mane or a pompom, and grows on hardwood trees such as beech in late summer and fall.
If you are ever unsure about whether a mushroom is edible, it is best to consult an expert or err on the side of caution and avoid consuming it.

How to differentiate between safe and toxic fungi
There are many edible mushrooms out there, but it is important to know how to differentiate between safe and toxic fungi to avoid foodborne illness. Here are some ways to help ensure you are consuming safe mushrooms:
Firstly, it is important to be able to identify the mushrooms you are consuming. Frank Hyman, a professional mushroom hunter, has written a book called "How to Forage for Mushrooms without Dying", which provides an in-depth guide to the foraging process and details 29 edible mushrooms. The book includes realistic pictures, notes on mushroom anatomy, and safety reminders to help readers identify mushrooms confidently. It is a great resource for beginners and seasoned mushroom hunters alike.
Another way to differentiate between safe and toxic fungi is to look at the characteristics of the mushrooms. For example, when trying to identify whether a mushroom is a delicious morel or a toxic false morel, slicing it in half can help; if it's hollow, it's safe to eat.
Additionally, it is important to be aware of the growing location of mushrooms. Hyman's book groups the 29 common mushrooms by their growing location, such as "treeborne mushrooms with gills". This information can help readers identify mushrooms in the wild more accurately.
Finally, it is crucial to exercise caution when consuming wild mushrooms. Even with proper identification, there is a risk of mistaking a safe mushroom for a toxic one. Therefore, it is always advisable to cook wild mushrooms thoroughly before consumption and to avoid eating any mushrooms that you are unsure about.

Mushroom anatomy and basics
Mushrooms are the fleshy, spore-bearing fruiting bodies of fungi, typically produced above ground on soil or another food source. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus. The word "mushroom" is most often applied to those fungi (Basidiomycota, Agaricomycetes) that have a stem (stipe), a cap (pileus), and gills (lamellae) on the underside of the cap. The gills produce microscopic spores that help the fungus spread across the ground or its occupant surface.
The most remarkable feature of mushroom anatomy is not what we see above the ground, but what lies beneath the soil's surface, in the mycelium. The mycelium is like a plant's root network, spreading over large distances underground to absorb nutrients and connect other fungi. Mushrooms reproduce via tiny spores that become airborne and spread across the forest floor to create new mushrooms in the network.
The common appearance of the mushroom anatomy that most people are familiar with consists of a cap and stem. The mushroom cap, also known as the pileus, is the structure on top of the mushroom that holds the gills or pores. They come in different shapes, sizes, colours, and textures. The cap is the most visible part of the mushroom, usually curved and similar to a hat. It houses the parts of the mushroom that produce spores. As a mushroom matures, the cap's size, shape, and texture may change, and in most cases, the older the mushroom gets, the more the cap expands. The cap is an umbrella and protects the spore-producing surface underneath it.
Some mushrooms, like lion's mane, are tooth fungi, meaning they have "teeth" or shaggy hair-like structures that hang around the mushroom and produce spores. Scales are part of a mushroom's anatomy that forms hard-shelled protection for fungi. They often appear in various shapes and sizes, contributing to the unique physical appearance of mushrooms in the wild. Scales typically appear on the cap but can also be present on the stem. They often appear as a result of cracking as the cap expands during growth but can also be seen when immature. Scaly caps can also be useful in identifying mushrooms, as numerous species have them.
Frank Hyman's book, "How to Forage for Mushrooms without Dying: An Absolute Beginner's Guide to Identifying 29 Wild, Edible Mushrooms", is a great resource for beginners wanting to learn how to identify edible mushrooms and avoid poisonous ones. It offers expert advice and easy-to-follow guidelines, along with realistic pictures and humour, making it a useful tool for anyone interested in mushroom foraging.

Responsible foraging and safety mnemonics
Responsible foraging and safety are paramount when it comes to mushroom hunting. Mushrooms are incredible organisms, and foraging is a rewarding activity that allows you to connect with nature and discover edible varieties. However, it is crucial to remember that some mushrooms are toxic and even lethal if misidentified. Here are some detailed guidelines and safety mnemonics to keep in mind:
Guidelines for Responsible Foraging:
- Educate yourself before embarking on a forage. Understand local laws, respect ecosystems, and learn the right techniques for collecting mushrooms.
- Minimize your impact on the environment. Only take what you need for personal use, and leave the habitat as untouched as possible.
- Prioritize sustainability. By taking fewer mushrooms, you encourage the release of more spores, leading to more mushrooms in future seasons.
- Consult multiple sources for identification. Use reputable guides, attend foraging classes, or go with an experienced forager to ensure accurate identification.
- Be cautious with new mushroom species. When trying a new variety, consume no more than two cooked teaspoons, then wait 24 hours before consuming more or trying another species.
- Avoid consuming wild mushrooms with alcohol. The presence of alcohol may produce stronger allergic reactions, and some mushrooms, like the Shaggy Mane (Coprinus comatus), have an adverse reaction with alcohol.
- Be mindful of toxic mushrooms. The Death Cap (Amanita phalloides) and Destroying Angel (Amanita bisporigera) are highly toxic and can be mistaken for edible varieties. The False Morel (Gyromitra spp.) also contains deadly toxins.
Safety Mnemonics:
- "When in doubt, throw it out!": If you are not 100% certain of a mushroom's identity, it is better to discard it than risk consuming a toxic variety.
- "If it's hollow, you can swallow": This mnemonic, popularized by Frank Hyman, helps distinguish the delicious Morel from the toxic False Morel. If the mushroom is hollow, it is likely safe to eat.
- "Happy wife, happy life": This phrase, used by Frank Hyman in a lighthearted context, emphasizes the importance of responsible foraging practices that respect the environment and the well-being of others.

Culinary and medicinal uses of mushrooms
Mushrooms are a valuable food source due to their high nutritional value and low calories, carbohydrates, fat, sodium, and cholesterol. They are also a good source of protein, vitamins, minerals, and antioxidants. The most commonly cultivated mushroom worldwide is Agaricus bisporus, followed by Lentinus edodes, Pleurotus spp., and Flammulina velutipes.
Mushrooms have a long history as a food source and are also important for their medicinal properties. They have been used in traditional Chinese medicine for thousands of years to improve health and longevity and have been considered a "Food of the Gods" by the Romans and a source of strength for warriors in battle by the ancient Greeks.
Today, mushrooms are recognized for their medicinal properties, including antimicrobial, anti-inflammatory, immunomodulatory, antidiabetic, cytotoxic, antioxidant, hepatoprotective, anticancer, antiallergic, antihyperlipidemic, and prebiotic properties. They are also reported to have neuroprotective, nephroprotective, osteoprotective, and hypotensive activities. The bioactive compounds in mushrooms are primarily responsible for their immunomodulatory effects, and they are used in cancer treatments to improve the quality of the patient's life.
When preparing mushrooms for cooking, it is important to wash and clean them carefully to remove any soil and grit. Mushrooms can be used whole, sliced, or diced, and they can be grilled, marinated, or added to sandwiches or wraps. It is essential to know which mushrooms are edible, as some wild mushrooms contain deadly toxins that can trigger fatal health issues.
