Mushrooms are a type of fungus, which is a separate kingdom from plants and animals. Fungi can be found everywhere on Earth, from forests to oceans, and in all climates and on every continent. They are primary decomposers, feeding on dead or dying trees, leaf litter, and other organic matter, and play a crucial role in maintaining the planet's ecosystems. Fungi also have a symbiotic relationship with plants, exchanging goods and helping them communicate. Humans share about 40% of their DNA with fungi, and mushrooms are a source of essential fatty acids and nutrients for humans. With over 10,000 identified species of mushrooms, they are indeed ubiquitous on Earth.

Mushrooms are found on every continent, including Antarctica
Mushrooms are indeed ubiquitous on Earth, found on every continent, including Antarctica. They are part of the fungi family, which is a kingdom of its own, separate from plants. Fungi are primary decomposers, feeding on dead or dying trees, leaf litter, and other organic matter, and unlocking nutrients that power our ecosystems. They are essential to the survival of most life forms on Earth.
Fungi have a mutually beneficial relationship with plants, exchanging goods and helping them communicate. They also connect plants to each other through mycelial networks, which allow older trees to nurture seedlings. However, this relationship can also be manipulated, with some trees "stealing" carbon or releasing harmful chemicals to sabotage their neighbours. Fungi are also closely related to animals, including humans, with about 40% of our DNA shared with them.
Mushrooms are the fruit bodies of fungi, with a short lifespan focused on producing spores for the fungus to spread. They come in a wide variety of shapes and colours, with over 10,000 species identified so far. Some mushrooms are edible and nutritious, with low fat and high protein and carbohydrate content. They also contain essential fatty acids like linoleic, oleic, and linolenic acids. Other mushrooms are hallucinogenic or poisonous, with some species causing more than 100 deaths per year globally.
Mushrooms are found in diverse environments, from forests and grasslands to deserts and ocean floors. They can be easily spotted during a walk in the woods or even in your own backyard. Their spores are so prevalent that we inhale them daily, and they are also present in many foods and beverages we consume, such as beer, wine, bread, cheese, and yoghurt. Fungi are all around us, and their importance to the natural world cannot be overstated.

Humans share about 40% of their DNA with fungi
Mushrooms are part of the fungi family, which is a kingdom of its own, separate from plants. Fungi are found everywhere on Earth, from forests to oceans, and in all climates and on every continent. They are essential and ubiquitous. They can be found in the food we eat, the medicines we take, and even in the air we breathe.
Fungi are closely related to animals, including humans. They share genetic characteristics that plants do not have. For instance, both mushrooms and humans store carbohydrate energy as glycogen, while plants use starch. Fungi and insects use the polysaccharide chitin to build cell walls, while plants use cellulose. Fungi also absorb oxygen and produce carbon dioxide, like humans, while plants do the opposite.
Humans share about 40-50% of their DNA with fungi, indicating that they have a common ancestor with animals. This means that humans are more similar to fungi than they are to plants. Fungi and humans can even contract the same viruses, such as the common fungal infection, ringworm.
The study of fungi is important not only for understanding their evolutionary relationship with other organisms but also for their potential benefits to human health. For example, magic mushrooms have been found to contain a psychedelic compound called psilocybin, which may be effective in treating certain mental health issues such as treatment-resistant depression. Additionally, mushrooms are a nutritionally well-balanced source of carbohydrates and proteins, with low fat concentrations. They are also a good source of essential fatty acids, such as linoleic, oleic, and linolenic acids, making them a healthy food choice.

Fungi are primary decomposers, connecting all living things in essential webs
Fungi are primary decomposers, playing a vital role in the planet's ecosystems. They are often the first to feed on dead or decaying organic matter, such as trees, leaves, and other detritus, breaking down complex molecules and unlocking nutrients. This process of decomposition and nutrient recycling is essential for the survival of plants and other organisms in the ecosystem. Without fungi, ecosystems would be overwhelmed with waste, and the soil would be depleted of nutrients, leading to the collapse of the entire food chain.
Fungi, including mushrooms, are ubiquitous on Earth and can be found in diverse habitats, from forests and grasslands to deserts and oceans. They form intricate networks with plants and other organisms, connecting all living things in essential webs of interdependence. These networks, known as mycelial networks, facilitate the exchange of goods and even enable communication between different plants. Fungi provide plants with essential nutrients, such as phosphorus, in exchange for carbon-rich sugars produced by the plants through photosynthesis.
The relationship between fungi and plants is deeply intertwined and symbiotic. Endophytic fungi, for instance, live within plant tissues, acting as adopted organs that help metabolise nutrients and protect the plant. Mycorrhizae, or "root fungi," form intimate entanglements with plant roots, enhancing the roots' ability to absorb minerals from the soil. This mutualistic relationship between fungi and plants dates back to the earliest days of life on land, when fungi played a pivotal role in the transition from ocean to shore, forming symbiotic bonds with early land plants.
Beyond their ecological significance, fungi also have a direct impact on human life. Humans are more closely related to mushrooms than to plants, and our daily lives are filled with fungal encounters. Fungi are used in food and beverage production, such as in bread, cheese, and beer. They are a source of essential fatty acids, contributing to a healthy human diet. Additionally, fungi play a role in medicine, with "magic mushrooms" being explored as a potential treatment for certain mental health issues, such as treatment-resistant depression.
In summary, fungi, as primary decomposers, hold a pivotal position in the web of life on Earth. They facilitate the recycling of nutrients, connect organisms through intricate networks, and contribute to the survival and well-being of plants, animals, and humans alike. Fungi are ubiquitous and deeply intertwined with the functioning of ecosystems, highlighting their essential role in sustaining life on our planet.

Mushrooms are a nutritionally well-balanced source of carbohydrates and proteins
Mushrooms are a low-calorie food, with one cup of raw mushrooms containing only 15 calories. They are also low in fat, with most of the fat being polyunsaturated. Mushrooms are a good source of protein, with around 2.2 grams of protein per cup. While this is a relatively small amount, it still contributes to a person's daily needs. Mushrooms also contain all the essential amino acids, which are necessary for life.
The protein in mushrooms is also of a high quality, with edible mushrooms providing a complete essential amino acid profile and meeting dietary requirements. This makes mushrooms a potential alternative to animal proteins, which can be low in quality due to a lack of one or more essential amino acids. Mushrooms are also a good source of bioactive protein hydrolysates, which are easily absorbed and can aid in digestion.
In addition to their nutritional benefits, mushrooms are also known for their health benefits. They are recognized for their ability to create savory rich flavors called umami, thanks to the presence of the amino acid glutamate. Mushrooms have been used as medicine for thousands of years, with traditional and folk medicine practitioners lauding them for their healing and cleansing properties. Modern research has also found that mushrooms may help to prevent or treat serious health conditions such as Alzheimer's, heart disease, cancer, and diabetes.
However, it is important to note that not all mushrooms are safe to consume. Many edible mushrooms have poisonous look-alikes, and even commonly consumed mushrooms like cremini mushrooms can be dangerous if not cooked properly. Therefore, it is important to only consume mushrooms from a reliable source and to cook them thoroughly to avoid any potential health risks.
