Mushrooms are a collection of species that belong to the fungi kingdom. They have a unique anatomy that differs across various species. The part of the mushroom that is visible above the ground or on the surface of a host is called the fruiting body or sporophore. It is made up of a cap and stem, with gills or pores underneath the cap that produce and disperse spores. The cap can come in different shapes, sizes, colours and textures, and its colour and texture vary not only across species but also according to the mushroom's stage of development. The mycelium, on the other hand, is the underground part of the fungus, which is made up of a network of thin fibres that spread out to absorb nutrients and connect with other fungi.

| General structure | Mushrooms are fungi, not plants or animals. They have two main parts: an above-ground "fruiting body" or "sporophore" and an underground "mycelium". |
| Fruiting body | The part of the mushroom that is visible and that we cook and eat. It is the fruit of the fungus, and its purpose is to produce and distribute spores so the fungus can reproduce. |
| Mycelium | A network of thin fibres that spread out for miles, like plant roots, absorbing nutrients and connecting with other fungi. |
| Cap | The topmost part of the mushroom, giving it its umbrella-like shape. It can be flat, conical, or spherical and comes in various textures and colours. It contains the spore-producing surface, made up of gills, pores, or teeth. |
| Gills | Thin, paper-like structures that hang from the underside of the cap and come in various colours. They produce and disperse spores. |
| Pores | Some mushrooms have pores instead of gills. These are tiny, tightly packed tubes that resemble a sponge. |
| Teeth | Some mushrooms have teeth or needles instead of gills, such as lion's mane. |

The cap, or pileus, is the umbrella-shaped top of the mushroom
The primary function of the cap is to protect the spore-producing surface, which is made up of gills, pores, or teeth. The gills are thin, paper-like structures that often hang from the underside of the cap and are responsible for producing and dispersing spores. The gills vary in colour and shape, and they play a crucial role in identifying mushroom species. The gills of some mushrooms, such as porcinis, are replaced by pores, which are tiny, tightly packed tubes resembling a sponge. Other mushrooms, like lion's mane, have teeth or needles instead of gills.
The cap's unique characteristics, including its shape, colour, and texture, are essential for identifying different mushroom species. Therefore, researching specific mushroom species and their cap characteristics is essential for proper identification. For example, the death cap, a highly poisonous mushroom species, has a white or yellowish stipe (stalk) with a "skirt" called a ring or annulus. The gills on the underside of the death cap's cap are white and closely packed, contributing to its distinct appearance.
The cap is an essential part of the mushroom's anatomy, providing protection for the spore-producing surface and contributing to the mushroom's overall structure and appearance. Its shape, colour, and texture can vary not only between species but also at different stages of the mushroom's development, making it a dynamic and fascinating feature of mushroom anatomy.

Gills are thin, paper-like structures under the cap that produce spores
Mushrooms are part of the fungi kingdom and have unique characteristics that differ between species. The mushroom itself, also known as the fruiting body, is the part that is visible above ground. The cap of the mushroom is the topmost part and gives the fungi its umbrella-like shape. The cap contains the spore-producing surface of the mushroom, which is made up of gills, pores, or teeth.
The function of the gills, called lamellae, is to produce and disperse billions of spores. Mushroom spores are microscopic, unicellular reproductive cells produced in the gills. The gills are protected by the cap, which shields them in the same way that an umbrella protects from rain or sun. The mushroom cap can be flat, conical, or spherical and can vary in colour and texture, depending on the species and stage of development.
The mushroom, or fruiting body, is the fruit of the fungus, and its primary function is to produce and distribute spores at the end of the mushroom's life cycle. These spores enable the fungus to reproduce and restart its life cycle. The spores are distributed from the fruiting body, which usually grows above the ground or on the surface of a host.

Mycelium is the underground network of cells that absorb nutrients
Mushrooms are part of the fungi kingdom, and their anatomy is complex and unique. The mushroom itself, or the 'fruiting body', is the part we see above ground. However, the mycelium is the hidden, underground part of the fungus. It is a network of thin fungal strands called hyphae, which spread out in search of nutrients. This network can be vast, covering large distances, and is often compared to a plant's root system.
The mycelium plays a crucial role in the growth and reproduction of fungi. It anchors the fungus to its growth substrate, allowing it to absorb nutrients from its environment. This process involves two stages. Firstly, the hyphae secrete enzymes onto the food source, breaking it down into smaller units. Secondly, these smaller units are absorbed into the mycelium through facilitated diffusion and active transport. The mycelium absorbs nutrients from dead and decaying organic matter, and its ability to break down food externally enriches the soil with bioavailable nutrition.
Mycelium is also vital for the health and growth of plants. It can form a symbiotic relationship with plant roots, known as mycorrhizal networks. Through this bond, there is an exchange of beneficial nutrients. The fungus receives sugars produced by the plant through photosynthesis and, in return, helps the plant absorb water and nutrients from the soil beyond the reach of its roots. This relationship can enhance the plant's immune response, protecting it from potential pathogens.
Mycelial networks can vary in size, with some remaining microscopic and others growing to colossal sizes. They can also exhibit a hierarchical structure, with a "trunk" or main mycelium and smaller "branches" extending from it. This network allows fungi to communicate and transport resources, contributing to the overall health and diversity of ecosystems.

Spores are microscopic, unicellular reproductive cells produced by the gills
Mushrooms are part of the fungi kingdom, and their anatomy can be quite complex. The part of the mushroom that is visible above the ground or on the surface of a host is called the fruiting body or sporophore. This is the part of the fungus that we commonly refer to as a mushroom. The mushroom's cap or pileus is the most noticeable part, and it gives the fungi its distinctive umbrella-like shape. The cap contains the spore-producing surface of the mushroom, which is made up of gills, pores, or teeth. The gills are thin, paper-like structures that are often found hanging from the underside of the cap. They come in a variety of colours and have distinct features that make them useful for identifying different species of mushrooms.
The function of the gills is to produce and disperse spores. Spores are microscopic, unicellular reproductive cells produced by the gills. They are essential for the reproduction of the fungus. At the end of a mushroom's life cycle, spores are spread, and some of these spores will go on to produce new mushrooms, thus restarting the cycle. The gills protect the spores until they are ready to be dispersed.
Not all mushrooms have gills. Some mushrooms, like porcinis, have pores, which are tiny, tightly packed tubes that resemble a sponge. Other mushrooms, like lion's mane, have teeth or needles instead of gills. The presence of gills, pores, or teeth can be an important indicator of whether a mushroom is safe to consume. For example, the deadly poisonous death cap mushroom has gills on the underside of its cap.
The mycelium is the underground part of the fungus that is vital for its growth. It is a complex network of cells that form thin fibres, similar to plant roots, and spread out in search of nutrients. The mycelium grows by absorbing nutrients from dead and decaying organic matter. It remains dormant until the conditions are perfect for fruiting and producing mushrooms.

The veil is a layer under the cap that peels away to reveal the gills
Mushrooms are a collection of species that belong to the fungi kingdom. They have a unique anatomy, and their visible parts—the fruiting body—only show a small part of their overall anatomy. The mushroom itself, or the fruiting body, is the part we see and cook with. However, there is an essential part of the fungal organism that remains hidden under the surface.
The veil is a layer of tissue found under the cap of a mushroom. It is a temporary structure that protects the developing spore-producing surface, or gills, of the mushroom. The veil is also known as the inner veil, to differentiate it from the outer or universal veil. The universal veil is the outer layer that protects the developing mushroom. The presence of a veil, its structure, and its characteristics vary among different mushroom species. Some have a very prominent veil, while others lack one entirely.
The veil is connected to the gill cavity and originates from the fundamental tissue that makes up the bulk of the cap and stem. As the mushroom grows, the looser portion of the veil tears off from the stem, exposing the gills. This is a critical milestone in the mushroom's lifecycle, indicating that it has reached maturity and spore release is imminent. The remnants of the veil can be seen as a ring around the stem or as fragments attached to the cap edge.
For cultivators, the veil's condition is an important indicator of the optimal timing for harvest. The development and rupture of the veil signal the transition to maturity and the onset of spore dispersal. Mushrooms are often harvested just before or as the veil breaks, as this stage is preferred for culinary and commercial purposes.
