Mushroom Magic: Unlocking Nature's Secrets

Mushrooms are the fruiting bodies of fungi, and they are neither plants nor animals. They have a unique and fascinating production process. The first mention of mushroom cultivation was in 1652, and the first record of year-round commercial production was in 1780. Today, mushrooms are cultivated in highly controlled environments, and the process is technical and scientific. The life of a cultivated mushroom begins in a laboratory, where spores are inoculated into sterile cereal grains. These grains become spawn, which can be sown into a substrate—a mixture of decayed organic matter that serves as a growth medium. Mushrooms can be grown indoors or outdoors, but they require specific temperature and humidity conditions to thrive.

Mushrooms are fungi, not plants

Mushrooms are fungi, and despite what many may think, they are not plants. Fungi are unique organisms that are neither plants nor animals. While they have been historically grouped with plants, fungi are, in fact, more closely related to animals than plants. This misclassification can be attributed to early taxonomies that divided living organisms into only two categories: animals or plants. However, modern genetic and evolutionary understandings have revealed that plants, fungi, and animals are distinct kingdoms with no common ancestor within the last half billion years or so.

Fungi have several characteristics that distinguish them from plants. Firstly, they lack chlorophyll, which is essential for plants to produce food through photosynthesis. Instead, fungi obtain nutrients by growing into and around their food source, secreting enzymes for external digestion, and then absorbing the digested nutrients. This process is similar to how animals obtain nutrients, further highlighting the distinction between fungi and plants.

Another key difference is in their respiratory processes. Plants take in carbon dioxide and release oxygen, which is vital for human survival. In contrast, fungi, like animals, require oxygen to thrive and expel carbon dioxide. Additionally, the cell walls of fungi contain chitin, a compound also found in the exoskeletons of arthropods like beetles and crabs. This distinct composition further separates fungi from plants, which lack this structural component.

Fungi play a crucial role in the decomposition of organic matter, particularly in breaking down complex compounds found in woody matter. This function is essential for nutrient cycling and carbon sequestration in terrestrial ecosystems. Without fungi, our forests would be overwhelmed with undegraded woody debris. Fungi also form symbiotic relationships with plants, known as mycorrhizae, where they mutually benefit from the processing of dead organic material and the exchange of nutrients and structural support.

While mushrooms are commonly consumed as vegetables, they are distinct from plants in their evolutionary history, biological processes, and unique health benefits. Understanding the classification of fungi as separate from plants is essential for accurately comprehending their biology, ecological significance, and potential applications.

They have been used in medicine for thousands of years

Mushrooms have been used for their nutritional and medicinal qualities for thousands of years. In ancient times, mushrooms were considered part of the plant kingdom, but today they are recognised as an independent group of organisms, classified under the Mycota kingdom.

Medicinal mushrooms such as chaga and reishi have been used to treat a variety of ailments. Chaga, for example, has been found to combat oxidative stress, which is linked to skin ageing, and may also prevent or slow the growth of cancer. Reishi, on the other hand, is known for its calming properties, thanks to the compound triterpene. Other types of mushrooms, such as shiitake, have been shown to help maintain healthy cholesterol levels and blood pressure.

Mushrooms are also a good source of vitamin D, which is essential for maintaining strong bones and boosting immune function. In addition, the polysaccharides found in mushrooms have been shown to stimulate the growth of healthy bacteria in the gut.

In recent years, there has been growing interest in the therapeutic benefits of psilocybin, also known as magic mushrooms. While still illegal in most places, some cities have decriminalised the possession of psilocybin mushrooms, recognising their potential health benefits. Research suggests that psilocybin could be beneficial in treating psychiatric and behavioural conditions, such as depression and PTSD. However, more research is needed to confirm these potential benefits.

The use of mushrooms in medicine is not without its risks. It is important to note that not all mushrooms are safe for consumption, and even experienced foragers can struggle to differentiate between edible and poisonous mushrooms. It is always advisable to seek professional guidance or cultivate your own mushrooms to minimise the risk of accidental poisoning.

Some mushrooms are poisonous

While mushrooms are a great delicacy and source of nutrition for many, it is important to remember that some mushrooms are poisonous and can even be deadly. Mushroom poisoning occurs when toxic mushrooms are ingested, and symptoms can range from mild gastrointestinal discomfort to death. It is estimated that out of the 100,000 known fungi species worldwide, about 100 are poisonous to humans. The majority of mushroom poisonings are not fatal, but it is still crucial to exercise caution when consuming mushrooms.

Mushroom poisoning can occur due to the misidentification of toxic mushrooms as edible ones. Some toxic mushrooms may closely resemble edible species in terms of colour, shape, and morphology, making it challenging even for experienced mushroom foragers to distinguish them accurately. For example, the Amanita family, which includes deadly species such as Amanita phalloides, can be mistaken for the Asian paddy-straw mushroom or other similar-looking species. Immature Amanitas, known as "Amanita eggs", can be particularly challenging to identify correctly.

To prevent mushroom poisoning, it is essential to familiarize yourself with both edible and toxic mushroom species before consuming any wild mushrooms. Learning about their key characteristics, such as colour, stem structure, and gill features, can help in accurate identification. Additionally, knowing the specific tests for certain mushroom families, such as the Agarics and Boletes, can further enhance your ability to distinguish between edible and poisonous mushrooms.

The effects of consuming poisonous mushrooms can vary depending on the type of toxin and the amount ingested. Some toxins, like amatoxins, can cause severe liver damage, while others, like phallotoxins, lead to gastrointestinal issues such as vomiting and diarrhoea. In some cases, mushroom toxins can affect the central nervous system, resulting in nausea, convulsions, coma, or even death. It is important to seek medical attention immediately if you suspect mushroom poisoning, as timely treatment can significantly impact the outcome.

It is also worth noting that some mushrooms, commonly known as "magic mushrooms", are considered illegal drugs due to their hallucinogenic effects. These mushrooms contain substances like psilocybin and psilocin, which can cause hallucinations, altered senses, and distorted perceptions of reality. While magic mushrooms are not typically associated with lethal outcomes, consuming large amounts or strong batches can lead to negative experiences, including intense paranoia, panic attacks, and long-term mental health conditions such as psychosis. Therefore, it is crucial to approach any type of mushroom with caution and always prioritize accurate identification and responsible consumption.

They can cause hallucinations

Some mushrooms contain psilocybin and psilocin, substances that can cause hallucinations. Used in large enough doses, these mushrooms have effects similar to the drug LSD. The length and intensity of each mushroom trip vary depending on the strength of the mushrooms and the amount consumed. The trip also depends on the user's mood, personality, expectations, and environment.

The effects of mushrooms generally begin after about 30 to 45 minutes and can last as long as 6 hours. Early effects typically include nausea and excessive yawning. After these initial effects, the "trip" begins. A trip might be mild, leaving a person feeling drowsy or relaxed. However, higher doses or stronger mushrooms can bring on hallucinations, anxiety, paranoia, and nervousness. The person may have a distorted sense of time, place, and reality.

Psilocybin mushrooms, also known as magic mushrooms, are naturally occurring and are consumed for their hallucinogenic effects. They are psychedelic drugs, which means they can affect all the senses, altering a person’s thinking, sense of time, and emotions. Psychedelics can cause a person to hallucinate, seeing or hearing things that do not exist or are distorted. The key ingredient in magic mushrooms is psilocybin. When psilocybin is taken, it’s converted in the body to psilocin, which is the chemical with psychoactive properties.

The dosage of psilocybin-containing mushrooms depends on the psilocybin and psilocin content, which can vary significantly between and within the same species. Psilocybin content is typically around 0.5% to 1% of the dried weight of the mushroom, with a range of 0.03% to 1.78%. Psilocybe cubensis, the most popular species, has been reported to contain 0.63% psilocybin and 0.6% psilocin, or about 1.2% of psilocybin and psilocin combined. Recreational doses of psilocybin mushrooms are typically between 1.0 and 3.5–5.0 g of dry mushrooms and 10 to 50 g of fresh mushrooms. A microdose of psilocybin mushrooms is about 10% of a recreational dose, and may be 0.1 to 0.3 g of dry mushrooms, taken up to three times per week.

It is important to note that the effects of magic mushrooms can vary widely and can be unpredictable. While some people may experience positive effects such as euphoria, hilarity, and a sense of oneness with nature, others may have terrifying thoughts, intense paranoia, panic attacks, and fears of death. Additionally, there is a risk of a bad trip, which can be influenced by factors such as a negative environment or the user's mood and expectations. In very rare cases, taking a large amount of mushrooms can lead to severe side effects and even death.

Mushrooms are a good source of vitamin D

The most common form of vitamin D found in mushrooms is vitamin D2, with lower levels of vitamins D3 and D4. While vitamin D3 is the most prevalent form found in animal-based foods, vitamin D2 is still beneficial in raising blood levels of vitamin D. Mushrooms are unique in their ability to produce vitamin D2, as they share this capability with humans.

The concentration of vitamin D2 in mushrooms depends on various factors, including the type and orientation of the mushrooms, whether they are sliced or whole, their distance from the UV source, their size, and the duration of exposure. For example, in button mushrooms, three pulses (1 second) of UV radiation generated 11.9 μg D2/g DM, while nine pulses (3 seconds) produced 20 μg D2/g DM. The maximum concentration of vitamin D2 (27 μg/g DM) was achieved after 12 pulses (4 seconds).

It is worth noting that the levels of vitamin D2 in UV-exposed mushrooms may decrease during storage and cooking. However, if consumed before the 'best-before' date, the vitamin D2 level typically remains above 10 μg/100 g fresh weight, which is higher than the amount found in most vitamin D-containing foods and comparable to the daily vitamin D requirement recommended internationally.

Worldwide mushroom consumption has increased significantly in the past four decades, and mushrooms have the potential to be the only non-animal, unfortified food source of vitamin D that can provide a substantial amount of vitamin D2 in a single serving. This makes mushrooms an excellent dietary choice for those seeking to increase their vitamin D intake.
