Mushrooms are a type of fungus and a living organism, but they are distinct from other living things like plants and animals. Unlike plants, mushrooms do not rely on sunlight for energy, instead, they obtain energy by breaking down dead organic matter. This is why mushrooms are often found growing on dead trees or logs. Mushrooms are the fruiting bodies of fungi, and they facilitate the distribution of spores, which are similar to seeds. The largest and oldest living organism on Earth is a mushroom and mycelial network found in Oregon, US, covering 2,384 acres and estimated to be 2,400 years old.

Mushrooms are fungi, but not all fungi are mushrooms
Mushrooms are a type of fungus, but not all fungi are mushrooms. Fungi are a separate branch of life from plants and animals, and they belong to the Fungi Kingdom. Fungi include yeasts, moulds, and mushrooms. Some yeasts and moulds are desirable, like brewer's and baker's yeast, while others are not, like yeast infections and mould on food.
Mushrooms are the "conspicuous umbrella-shaped fruiting body" of certain fungi, typically of the order Agaricales in the phylum Basidiomycota. The term "mushroom" is usually used to refer to the edible fruiting bodies, while the term "toadstool" is reserved for the inedible ones. Some mushrooms are poisonous, like the death cap, while others are edible, like the Portabella, Button, Cremini, Shiitake, and Oyster mushrooms.
Fungi, including mushrooms, get their energy from decomposing plant and animal matter, absorbing energy from dead plants and animals. They do not need sunlight to grow, which is why mushrooms can be found in dark, damp places like under logs or in caves, as well as in sunny spots like on lawns or the sides of trees.
Mycology is the scientific study of fungi. Humans have used fungi for various purposes since ancient times, including as tinder, for medicinal purposes, and as a food source.

Mushrooms are living organisms, but they are not plants or animals
Mushrooms are the fruiting bodies of some types of fungi. They are the visible component of a vast organism that often stretches for long distances underground, primarily in forests. Most of the fungus is actually hidden underground or in decaying wood or dying tree roots. The largest and oldest living creature on Earth is a mushroom and mycelial network found in the Blue Mountains of Oregon, covering 2,384 acres.
Mushrooms get their energy from decomposing plant and animal matter, unlike plants, which get their energy from the sun. This means that mushrooms can be found in dark, damp places like under logs or inside caves, but they can also be found in sunny spots like lawns or the sides of trees. They are versatile organisms that break down dead things like leaves and plants, which is why they are often seen growing on dead trees or logs.
Some mushrooms are edible and can be bought at grocery stores, while others are poisonous. Only 2% of fungi species have been identified, so it is very dangerous to pick and eat mushrooms found outside unless you are with a mushroom expert.

Mushrooms get their energy from decomposing matter, unlike plants
Mushrooms are living organisms, but they are very different from other living things like plants and animals. They are part of the Fungi Kingdom of life. Fungi are an entirely separate branch of life from plants and animals.
Unlike plants, mushrooms do not rely on sunlight to generate energy. Instead, they obtain their energy from decomposing organic matter. This includes dead plant and animal matter, as well as other sources such as rotting wood. Fungi break down these complex organic compounds into simpler ones, which they then absorb and utilise for growth and reproduction.
The ability of fungi to decompose and convert complex compounds is particularly notable in the case of lignin. Lignin is a challenging compound to break down, found in wood. Certain fungi possess the biochemical tools to digest lignin, converting it into simpler molecules and nutrients that can then be absorbed by plants. This unique partnership between fungi and plants forms a mycorrhiza, which enhances the absorption of nutrients and water from the soil.
The growth of mushrooms is also distinct from that of other organisms. Instead of cell division, mushrooms grow by pumping water into pre-formed cells. This process requires less energy and enables mushrooms to grow rapidly, especially after rainfall. The visible fruiting bodies of mushrooms, which we typically associate with the term "mushroom", are only a small part of the entire fungus. The majority of the fungus consists of a network of microscopic threads, known as hyphae, that extend underground or through organic matter, absorbing nutrients and energy.

Some mushrooms are edible, while some are poisonous
Mushrooms are a part of the Fungi Kingdom and are living organisms, but they are distinct from other living things like plants and animals. They differ from plants in that they do not derive their energy from sunlight; instead, they obtain it by decomposing plant and animal matter. This is why mushrooms can be found in dark, damp places like under logs or in caves, as well as in sunny spots.
While some mushrooms are edible, others are poisonous. This makes it dangerous to pick and consume mushrooms found in the wild, unless you are with a mushroom expert. Poisonous mushrooms can cause severe gastrointestinal distress and, in some cases, lead to nausea, convulsions, coma, and even death. Some rules of thumb for avoiding poisonous mushrooms include steering clear of those with white gills, a skirt or ring on the stem, and a bulbous or sack-like base. It is also advisable to avoid mushrooms with any red on the cap, stem, or pores, as well as those that stain blue when cut in half vertically.
Identifying edible mushrooms can be challenging due to the diverse nature of fungi, and even similar-looking mushrooms can have varying levels of toxicity. For instance, the Yellow Morel is a distinct and beginner-friendly edible mushroom, but its look-alike, Gyromitra spp., contains a highly toxic and carcinogenic chemical called gyromitrin. Chanterelles, though celebrated as a wonderful mushroom for beginners, can be easily mistaken for the poisonous Jack O'Lantern Mushroom, which causes severe gastrointestinal issues.
It is crucial to properly identify mushrooms before consumption and to try a small amount of any new species to check for allergies or sensitivities. While some general guidelines help identify poisonous mushrooms, the best approach is to only consume mushrooms that have been positively identified as edible and to avoid those that are uncertain.
Mushrooms: Invasive or Not?

Mushrooms are important decomposers and nourish plants through their mycelium
Mushrooms are the fruiting bodies of fungi, which are a separate branch of life from plants and animals. Fungi are essential decomposers in most ecosystems, breaking down complex organic matter into simpler inorganic materials. This process makes vital nutrients available to primary producers, usually plants and algae. Fungi acquire their food by absorbing dissolved molecules, secreting digestive enzymes into their environment, and growing. Unlike plants, they do not need sunlight and are not dependent on photosynthesis, allowing them to thrive in dark, damp places like under logs or in caves, as well as in sunny spots.
Fungi play a critical role in the decomposition of organic matter and nutrient cycling and exchange in the environment. They are the principal decomposers in ecological systems, breaking down dead plant and animal matter into water, carbon dioxide, and simple compounds containing nitrogen, phosphorus, and calcium. These nutrients are then added back to the soil or water, becoming available to plants for growth and reproduction. Fungi's ability to break down complex organic materials makes them nature's recycling system.
Mushrooms, as a part of the fungi family, contribute significantly to the decomposition process. They release spores, similar to seeds, which grow into new fungi that continue the decomposition and nutrient cycling process. This makes mushrooms essential for nourishing plants and maintaining the health of ecosystems.
Additionally, fungi form mutualistic relationships with other organisms, including plants, animals, and even other fungi. Lichens, for example, are a mutualism between a fungus and a photosynthetic organism, such as an alga or cyanobacterium. In this relationship, the fungus provides minerals and protection from dryness and excessive light by encasing its partner in its mycelium. In return, the photosynthetic organism contributes carbon and energy in the form of carbohydrates. This mutualistic relationship highlights how fungi, through their mycelium, can nourish and support the growth of other organisms.
Fungi, including mushrooms, also have important applications in human nutrition, medicine, and industrial processes. They are a direct source of food for humans and play a role in fermenting various food products, such as bread, cheese, and alcoholic beverages. Additionally, secondary metabolites from fungi are used to produce antibiotics and anticoagulants. Overall, mushrooms are essential decomposers that contribute significantly to the nourishment of plants and the maintenance of healthy ecosystems.
