Mushroom Varieties: A Surprising Number To Discover

Mushrooms are a diverse kingdom of fungi, with an estimated 2 to 3 million species, of which only about 14,000 have been described so far. They come in a wide range of shapes, sizes, colours, and flavours, and can be found in various environments, from forests to farms. With their unique characteristics and roles in nature, mushrooms have captivated humans for centuries, whether it's for their culinary delights, medicinal properties, or ecological significance. From the simple white button mushroom to the exotic reishi mushroom, the world of mushrooms offers a vast array of experiences and benefits that continue to fascinate and nourish us.

There are over 14,000 known species of mushrooms, with new ones being discovered regularly

Mushrooms are the fleshy, spore-bearing fruiting bodies of fungi, typically produced above ground on soil or another food source. Toadstool generally refers to a poisonous mushroom. There are over 14,000 known species of mushrooms, with new ones being discovered regularly. 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) on the underside of the cap.

"Mushroom" also describes a variety of other gilled fungi, with or without stems; therefore, the term is used to describe the fleshy fruiting bodies of some Ascomycota. The gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as "bolete", "truffle", "puffball", "stinkhorn", and "morel".

Some mushrooms are edible and have tastes ranging from sweet to nutty, and others even taste like lobster. Other varieties can be used for their medicinal benefits to boost your immune system, lower blood pressure and cholesterol, and may even be useful for treating cancer and other serious diseases. Some popular edible mushrooms with medicinal properties include Shiitake, Tremella, and Maitake.

Mushrooms that deviate from the standard morphology are given more specific names. For example, some have pores underneath and are usually called "boletes", while others have spines and are called "tooth fungi", like the hedgehog mushroom. The term "mushroom" has also been used for "polypores", "puffballs", "jelly fungi", "coral fungi", "bracket fungi", "stinkhorns", and "cup fungi".

Mushrooms are used for cooking, dyeing, medicine, and fire-starting

There are approximately 14,000 known species of mushrooms, with a wide range of uses. They can be farmed or foraged, and vary in size, shape, texture, and flavour. Mushrooms are used for cooking, dyeing, medicine, and fire-starting.

Cooking

Mushrooms are commonly used for cooking, with many varieties being edible and commercially grown. The most common variety is the white button mushroom, which has a mild flavour and soft texture, making it adaptable to various recipes and preparations. Other edible varieties include cremini, portobello, shiitake, oyster, and enoki mushrooms, each with its own unique characteristics and flavours.

Dyeing

Mushrooms have been traditionally used for dyeing wool and other natural fibres, producing strong and vivid colours across the spectrum. The Inonotus hispidus, for example, can yield a range of shades from deep burnt orange to yellow gold, depending on the age of the fruiting body. The Phaeolus schweinitzii is another popular choice for dyers, as it consistently produces colour even if undercooked or overcooked.

Medicine

Mushrooms have a long history of medicinal use, dating back to ancient civilisations. Ancestors like Hippocrates and the alchemist Tao Hongjing recognised the anti-inflammatory and wound-healing properties of certain mushrooms. Modern science has also validated the medicinal potential of mushrooms, uncovering a vast array of novel constituents that warrant further exploration.

Fire-Starting

Some mushrooms, known as tinder fungi, are natural fire-starters due to their flammability. Chaga, or "tinder fungus," is a chunky black mushroom that grows on birch trees in cool northern forests. It ignites easily, smoulders for hours, and emits a pleasant aroma, making it a useful tool for starting fires in outdoor settings.

Mushrooms are queer organisms that don't fit into the plant or animal kingdom

Fungi are more closely related to humans than they are to plants. They respire like humans, needing oxygen to thrive while expelling carbon. In contrast, plants take in carbon and expel oxygen. This difference in respiration is one of the reasons why fungi are classified separately from plants.

Another reason for the distinct classification of fungi is that they are immobile and have rigid cell walls that support them. These characteristics were sufficient for early scientists to determine that fungi are not animals and to initially lump them together with plants. However, with advancements in molecular biology, it has become clear that fungi are more closely related to animals than plants.

The unique characteristics of fungi have led to their distinct classification from plants and animals. Mushrooms, as members of the fungi kingdom, offer a diverse range of benefits. Some varieties of mushrooms are edible and have tastes ranging from sweet to nutty, while others are prized for their medicinal properties, such as boosting the immune system, lowering blood pressure, and potentially treating cancer and other serious diseases.

Mushrooms can be poisonous, toxic, mind-altering, antibiotic, antiviral, or bioluminescent

There are over 10,000 varieties of mushrooms, and they come in all shapes and sizes. While most are edible and nutritious, some are poisonous and toxic, and should be avoided. Mushrooms can also be mind-altering, antibiotic, antiviral, or bioluminescent.

Some mushrooms are toxic and can be incredibly dangerous, even fatal. The 'destroying angel', for example, is a species of all-white mushrooms that bear a striking resemblance to edible button mushrooms. This toxic fungus can cause vomiting, delirium, convulsions, diarrhea, liver and kidney failure, and even death. Similarly, the 'death cap' mushroom, found throughout Europe, is often mistaken for edible straw mushrooms and Caesar's mushrooms. It contains amatoxins, which quickly damage cells in the body, leading to severe abdominal pain, vomiting, and bloody diarrhea. Other toxic mushrooms include the 'deadly dapperling', which contains amatoxins, and the 'Jack O'Lantern' mushroom, which has a slight bioluminescent feature, with its gills glowing a soft greenish light in the dark.

Mushrooms have also been praised for their medicinal properties and are known to possess antimicrobial compounds that can inhibit or kill harmful bacteria, fungi, and other microbes. These compounds, called phytochemicals, include phenolics, terpenoids, flavonoids, alkaloids, steroids, saponins, and polysaccharides. They can help prevent and treat infectious diseases, especially in light of the development of antibiotic resistance.

Additionally, mushrooms contain antiviral bioactive compounds that have been studied for their potential to prevent and treat viral diseases. These compounds exhibit antiviral activity by stimulating the immune system and directly inhibiting viral replication. For example, beta-glucans, found in many mushroom species, activate immune cells to attack and eliminate virus-infected cells. Similarly, lentinan, extracted from shiitake mushrooms, has been shown to directly inhibit the replication of the HSV virus.

Lastly, some mushrooms are known for their mind-altering properties. Psilocybin, often referred to as 'magic mushrooms', are naturally occurring psychedelic drugs that can alter a person's thinking, sense of time, and emotions. They can cause hallucinations, perceptual changes, and what is commonly known as a ''trip', which can be positive or negative, depending on the environment and the person's state of mind.

Mushrooms are cultivated in many countries, with China being a major producer

Mushrooms are cultivated in many countries, with China being the largest producer by far. In fact, China accounts for more than 75% of the world's total mushroom production. The United States is a distant second, producing about 5% of the world's mushrooms. Other countries that produce mushrooms include the Netherlands, Poland, Canada, France, the United Kingdom, Spain, and India. Each of these countries contributes between 1-3% of the world's mushrooms.

There are over 10,000 varieties of mushrooms, with some being edible and others poisonous. Mushrooms are a versatile ingredient in the kitchen, adding flavour and texture to dishes. Some popular edible mushrooms include button mushrooms, cremini mushrooms (also known as Baby Bellas), portobellos, maitake, shiitake, tremella, and oyster mushrooms. Mushrooms can be used in a variety of dishes, such as soups, stews, pizzas, ramen, and burgers.

While some mushrooms are cultivated on a large scale, others are wild and can only be found in certain environments. Wild mushrooms include truffles, morels, and chanterelles. It is important to be able to identify wild mushrooms properly before consuming them, as some varieties are poisonous and can cause serious health issues.

In addition to their culinary uses, mushrooms have also been used for their medicinal properties. Some varieties of mushrooms are believed to boost the immune system, lower blood pressure and cholesterol, and may even be useful in treating cancer and other serious diseases.

Overall, mushrooms are a diverse and fascinating food source, with a wide range of uses and benefits. Their cultivation in various countries, with China as a major producer, has made them a popular ingredient in cuisines around the world.
