Mushrooms are a type of fungus that are alive and part of the Fungi Kingdom of life. They are different from other living things like plants and animals because they get their energy from decomposing plant and animal matter, rather than from the sun. This means they can be found in dark, damp places like caves or under logs, but also in sunny spots like lawns or the sides of trees. Mushrooms have a complex life cycle, forming from spores that germinate and develop into a network of connected filaments called a mycelium, which then forms a new fruiting body. The largest and oldest living organism on Earth is a mycelial network found in Oregon, USA, covering 2,384 acres and estimated to be 2,400 years old.

What You'll Learn
Mushrooms are fungi
The mycelium then forms a new fruiting body, and the process begins anew. A fungus reproduces in all seasons, primarily in dark, moist conditions with moderate temperatures. Mushrooms can appear at any time, but they are most commonly seen in spring and fall.
The term "mushroom" is used to describe the fleshy fruiting bodies of some Ascomycota. The gills of the mushroom produce microscopic spores, which help the fungus spread across the ground or its occupant surface. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus. Hence, the word "mushroom" is most often applied to those fungi that have a stem (stipe), a cap (pileus), and gills (lamellae, sing. lamella) on the underside of the cap.
"Mushroom" also describes a variety of other gilled fungi, with or without stems. Forms deviating from the standard morphology usually have more specific names, such as "bolete", "truffle", "puffball", "stinkhorn", and "morel". The term "mushroom" has been used for polypores, puffballs, jelly fungi, coral fungi, bracket fungi, stinkhorns, and cup fungi. Thus, the term is more one of common application to macroscopic fungal fruiting bodies than one having precise taxonomic meaning.

They get energy from decomposing matter
Mushrooms are unique organisms that play a vital role in the ecosystem, and their ability to derive energy from decomposing matter is a key aspect of their function. This process not only sustains mushrooms but also contributes to the overall health of the environment.
Unlike plants, which generate energy through photosynthesis, mushrooms are heterotrophs, meaning they obtain their energy from organic matter. They achieve this through a process called saprotrophy, where they secrete enzymes that break down complex organic materials into simpler forms that can be absorbed and utilized. This ability to decompose matter is essential for the recycling of nutrients in the ecosystem.
The primary source of energy for mushrooms is lignin, a complex polymer found in wood and plant biomass. Lignin is a challenging substance to break down, but mushrooms have evolved enzymes that can effectively degrade it. By secreting these enzymes into their surroundings, mushrooms can unlock the energy stored within lignin and use it for growth and metabolism.
This process of obtaining energy from decomposing matter is slow and gradual, which is why mushrooms are often associated with patience and persistence in nature. As they slowly break down organic materials, they release nutrients that benefit other organisms in the ecosystem, contributing to the overall nutrient cycle.
The ability of mushrooms to derive energy from decomposing matter makes them important recyclers in the natural world. They play a crucial role in breaking down dead plants, fallen leaves, and wood, returning valuable nutrients to the soil that can be utilized by other living organisms. This process enhances soil fertility and promotes the growth of other plants and microorganisms.

They have spores
Mushrooms are a kind of fungus and part of the Fungi Kingdom of life. They are living organisms, but they differ from other living things such as plants and animals. Unlike plants, mushrooms do not rely on the sun for energy. Instead, they feed on decomposing plant and animal matter, absorbing energy from dead plants and animals. This is why mushrooms are often found growing on dead trees or logs. They can also be found in dark, damp places like under logs or in caves, but their versatility means they can also be found in sunny spots, such as on lawns or the sides of trees.
Mushrooms are the fruiting body of a fungus, and they have spores. The presence of spores is one of the characteristics used to identify a mushroom. The spores are produced on the gills of the mushroom and are its reproductive units. These gills are found underneath the cap of the mushroom, which is the part that is usually referred to when talking about mushrooms. The spores are called basidiospores, and they fall in a fine rain of powder from under the caps. The microscopic process involves the basidiospores being shot off basidia and then falling between the gills in the dead air space.
The colour of the spore print, which is the powdery impression formed when the cap is cut off and placed gill-side-down overnight, is useful for classifying and identifying mushrooms. Common colours include white, brown, black, purple-brown, pink, yellow, and creamy, while blue, green, and red are rare. The spores are hardy and can survive for years, but they require moisture and the right temperature.
The process of reproduction in fungi involves the release of spores, which are carried to a place where they will germinate, combining sexually, asexually, or in other ways. Once the spores germinate, they form a hypha, which is a single filamentous body that eventually grows into a full network of connected hyphae, called a mycelium. The mycelium then forms a new fruiting body, and the cycle begins again.

They can be poisonous or edible
Mushrooms can be poisonous or edible, and it is critical to be able to distinguish between the two. The terms "mushroom" and "toadstool" date back to the 15th and 16th centuries, with "toadstool" implying an inedible, poisonous fungus. However, the delineation between edible and poisonous fungi is not always clear-cut, and there are some general rules to follow to avoid poisonous mushrooms. It is important to avoid mushrooms with white gills, a skirt or ring on the stem, and a bulbous or sack-like base called a volva, as these are members of the deadly Amanita family. Mushrooms with red on the cap or stem should also be avoided, as should any mushrooms with gills that bruise to a bright chrome yellow colour. Some mushrooms, such as the Jack O'Lantern mushroom, cause severe gastrointestinal distress, while others like the Destroying Angel (Amanita verna) are deadly.
On the other hand, some edible mushrooms have distinct characteristics that make them safer for novice foragers. The Yellow Morel is considered beginner-friendly due to its distinct appearance. The Giant Puffball is edible when its exterior flesh is firm and the inside is completely white, before spore development. The Beefsteak Fungus, Porcelain Fungus, and Cauliflower Fungus are also considered safe for consumption.
For more experienced foragers, the Shaggy Mane is a good edible mushroom, although survivors of Amanita poisoning have mistakenly identified it as the toxic Destroying Angel. Chanterelles are also considered a wonderful mushroom for beginners, although they may not be as beginner-friendly as some claim due to their similarity to the poisonous Jack O'Lantern mushroom.
While modern identification of mushrooms is becoming increasingly molecular, standard methods of identification are still used by most and require a basic understanding of their macroscopic structure. Tasting and smelling mushrooms carry their own hazards due to poisons and allergens, so it is important to only consume a small amount of any new species before committing to a full meal.

They can be identified by their macroscopic structure
The term "mushroom" is loosely defined and is used to describe a wide variety of fungi. While the agarics and boletes include most of the forms known as mushrooms, other groups of fungi are also considered mushrooms by laymen. These include hedgehog mushrooms, which have teeth, spines, or warts on the undersurface of the cap, and polypores, shelf fungi, or bracket fungi, which have tubes under the cap.
While modern identification of mushrooms is increasingly molecular, the standard methods for identification are still used by most and have developed into a fine art. The standard methods for identification rely on a basic understanding of the macroscopic structure of mushrooms.
The macroscopic features of the fruiting body were once the primary basis for fungal classification. Even today, these features are still very useful for identifying mushrooms. The presence of juices upon breaking, bruising reactions, odors, tastes, shades of color, habitat, habit, and season are all considered when identifying mushrooms.
Some mushrooms have a skirt of tissue (called a ring or annulus) around the stem, and some have a cup-like structure (or volva) around the base of the stem. Most mushroom genera have neither a ring nor a volva, so the presence of one or both of these features is very helpful for identification.
Another important macroscopic feature for identifying mushrooms is the spores. Their color, shape, size, attachment, ornamentation, and reaction to chemical tests are often crucial for identification. The color of the powdery print, called a spore print, is also useful for classifying and identifying mushrooms. Spore print colors include white (most common), brown, black, purple-brown, pink, yellow, and creamy, but almost never blue, green, or red.
