Mushroom Anatomy: Everything You Need To Know

Mushrooms come in many different shapes and sizes. In this post, you will learn everything you need to know about the anatomy of mushrooms.

Mushrooms are incredibly nutritious fungal fruiting bodies that can have health benefits beyond the nutrients they provide to our bodies. Mushrooms come in many shapes and sizes and can be found on forest floors in many areas around the world.

Some mushrooms have the same anatomical features. This guide will describe the general structure and anatomy of mushrooms and provide information on edible mushrooms and their most delicious characteristics. Come on a mushroom trip with us now!

Overview of fungi

Most people already know what a mushroom is and what mushrooms generally look like. When we imagine a mushroom, we usually conjure up an image of a stem and a cap. However, the anatomy of mushrooms actually has many different characteristics, and there is much more beneath the surface.

The most remarkable feature of mushroom anatomy isn’t what we see above ground—the real intrigue lies below the soil surface, in the mycelium.

Mushrooms reproduce through tiny airborne spores that spread throughout the forest to create new mushrooms in the network. Some mushrooms can develop a stem and cap as they mature.

Not all mushrooms are edible – some are incredibly poisonous. Mushrooms that we buy in grocery stores and can eat are called edible mushrooms, and those that may provide our body with extensive health support are called functional mushrooms.

Below are the main characteristics and anatomical structures of mushrooms.

The fruiting body

The mushroom fruiting body is any part of the mushroom. From the parts we use when making garlic mushrooms, mushroom linguine or any other mushroom recipe to the parts of the mushroom anatomy responsible for reproduction. It produces spores that help the mushroom network to spread, grow and thrive.

The anatomy of each mushroom is different. Some mushrooms have gills, some have pores, some have teeth, some have a ring, and some have a bulb. These are some components of the mushroom fruiting body:


The mushroom cap is the most visible part of the mushroom. It is usually curved in shape, similar to a hat, and sits on top of the mushroom stem.

The cap is also known as the mushroom pile and houses the spore-producing parts of the mushroom. Many mushrooms have small caps and others have bright and colorful caps.

As a mushroom matures, the size, shape and texture of the cap can change – in most cases, the older the mushroom, the more the cap swells.

The cap is an umbrella and protects the seed-producing surface below it. If the spore-producing surface gets wet, this will make the spores heavier and unable to travel through the air in the mushroom’s reproductive cycle.

Some mushrooms do not have caps, such as Puffballs, Lion’s Mane or Cordyceps. Some have a bunch of tiny caps in a cluster like a Maitake, and some mushrooms like the Tremella make structures that look like a sea sponge.

Some fungi do not even produce mushrooms and instead create dense structures such as truffles, Poria Cocos or most of the Chaga life cycle.

Gills And Pores

Mushroom gills and pores are much less visible than the stem or cap, as they are on the underside, which is why most people are unaware of their existence.

When you look under a mushroom cap, you may see some gill-like structures, which are pleasant and satisfying to the touch. Mushroom gills are responsible for helping the mushroom produce spores and disperse them into the air during the reproductive process.

Not all mushrooms are boletus mushrooms. Some have a different structure under the mushroom cap and some have pores. The pores under a mushroom cap look like tiny little holes and have a similar texture to the surface of a sponge.


If a mushroom doesn’t have gills or pores, it will probably have teeth. The lion’s mane mushroom is an excellent example of a mushroom with teeth. Teeth are small, soft tooth-like structures. Another great example would be a Hedgehog mushroom with teeth under its cap. Many mushrooms have teeth and perform the same function as mushroom gill structures that disperse spores.


Mushroom spores play an essential role in the life cycle of mushrooms. Spores are similar to the seeds of a plant. Some mushrooms carry these seeds through the air in the reproductive cycle. Other fungi transport them through or rely on water animals to eat the mushrooms and produce the spores that will produce the mushrooms from the manure. Other mushrooms rely on insects for transport.

You will probably never see mushroom spores, as they are so tiny they can only be seen under a microscope, unless you catch them in large quantities, which may look like dust or powder. These tiny spores help identify mushrooms and contain all the genetic material necessary to create a new mushroom. If you see spores in large quantities, you can look at the color of the powder to identify certain mushrooms.

When a mushroom is in the final stages of its reproductive cycle, it will release spores and disperse them through the air or by animals and insects. When germinated, spores usually need a warm, moist and shaded area to thrive, ball fungi are different. Some fungi have even learned to thrive in the frozen snowy Antarctica, the harsh radioactive environments of Chernobyl, or even under the ocean.


Not all mushroom stems have a ring. The ring is around the base of the stem and comes out like a skirt. The annulus is a partial veil that surrounds and protects the gills while the mushroom grows. As the mushroom cap expands and grows, it outgrows the protective veil and the veil breaks, detaching a ring around the mushroom stem.

Some rings are fragile fibers, like spider webs, and some are thicker. The thickness, color and shape of the ring can help people identify the mushroom.


Some growing mushrooms emerge from the soil and are protected by a bulb that surrounds all parts of the mushroom anatomy as they grow upwards. Not all mushrooms have a volva, but they are a key identifying feature if a mushroom has one at the base of the stem.

As the mushroom life cycle progresses, the volva remains at the base of the stem while the rest of the mushroom fruiting bodies grow upwards. You can identify the mushroom volva by looking for a cup-like structure at the base of the stem.

Few people—except those who study mycology—Know that the anatomy of mushrooms extends beyond the fruiting bodies. However, a complicated part of some mushrooms is located underground – the mycelium.

The mycelium grows below the soil surface, connecting multiple mushroom fruiting bodies in a network. The mycelium helps feed the fungus by transporting and absorbing nutrients from substrates such as tree bark and plant roots.

Most interestingly, the mycelium does not only support the growth and health of the mushroom network. It extends into the forest ecosystem, supporting the growth of other plants by supplying them with nutrients.

It also communicates with the plants in the ecosystem, helping to reduce competing growth and ensuring that all surrounding plants thrive.

Not all fungi produce mushrooms. There are an estimated 5,000,000 species of fungi. Of these, only 120,000 have been described. Of these 120,000, only 14,000 produce mushrooms. It is estimated that over 95% of land plants have a mycorrhizal association which is the mycelium that attaches to plant roots and forms a symbiotic relationship. Most of these mycelial networks do not actually produce above-ground mushrooms and reproduce by other means.

It is important to understand that mushrooms and mycelium are two different things. Although they are both fungi, mycelium is not part of the anatomy of mushrooms, it is part of the life cycle of some mushrooms.

Which parts of the mushroom can be eaten?

The fruiting body provides the most nutritional value and is most often used in mushroom supplements. You can also embed it fruiting body of functional mushrooms in your favorite mushroom recipes.

Mushroom supplements containing the mushroom mycelium are often diluted with a filler since the mycelium is grown on a substrate.

Mushroom growers often use rice or oats as a substrate, and these substances are difficult to separate from the mycelium in the preparation of supplements. So the manufacturer will probably dilute the product with mycelium extract, with fillers.

So when it comes to consuming mushrooms or mushroom extracts, it is best to stick to it fruiting body of mushroom anatomy.

Health benefits of mushrooms

Some mushrooms provide health benefits as well as nutrients. Mushrooms that offer health benefits are known as functional mushrooms.

You can eat the most functional mushrooms and incorporate them into your favorite recipes—or you can take mushroom supplements. Mushroom supplements come as powders, gums, tinctures, and capsules so you can incorporate them into your daily rituals as you see fit!

Here are some of the main benefits of mushrooms for your overall health and well-being.

They support functions related to immunity

Your immune system is responsible for fighting pathogens, viruses and bacteria that threaten your vital systems. Supporting your immune system can help you maintain good health.

Many functional mushroom species are beneficial in supporting immune-related functions. A functional mushroom supplement can act as a protective barrier against nasties.

The nutrients and compounds found in functional mushrooms can be beneficial in supporting your body’s natural defenses. If you often get sick during the winter, you may want to add a mushroom supplement to your routine to get fantastic immune system support.

Their potassium content can support already healthy blood pressure levels

Maintaining healthy blood pressure is essential for overall health and well-being. If you suffer from occasional stress, your blood pressure can become dysregulated and rise.

Many disorders can cause your blood pressure to rise. Your body naturally regulates your blood pressure to ensure that all your muscles and organs have access to oxygenated blood.

You can give your heart a helping hand in keeping blood pressure at healthy levels by adding a functional mushroom supplement to your daily diet. The high potassium content in functional mushrooms can help support a healthy cardiovascular system.

Mushrooms can be a good source of protein and nutrition

Mushrooms are delicious in many recipes and can provide our body with valuable protein and nutrients.
