Mushrooms: Immortal Or Just Resilient?

Mushrooms are a type of fungus with a variety of uses and health benefits. They are a popular food ingredient and can be consumed raw or cooked. However, not all mushrooms are safe for consumption. Poisonous mushrooms contain toxins that can cause serious health issues, including organ failure and death. The time it takes for symptoms of mushroom poisoning to appear varies, and in some cases, symptoms may not manifest until days or weeks after ingestion. Therefore, it is essential to properly identify mushrooms before consuming them. While some mushrooms may be harvested and consumed at specific stages of maturity, others may only be suitable for certain culinary or recreational purposes.

Mushrooms die when they can't regrow their mycelium

Mushrooms are part of the fungi family and do not have brain activity like animals, so it is difficult to determine when they die. One source suggests that mushrooms have a 1-2 week window of life when they sprout before they die. However, the real way a mushroom dies is when it matures enough that it loses the ability to regrow the entire mycelium it spawned from.

Mycelium is a thin, thread-like region of subterranean fungi. It is responsible for the regrowth of mushrooms after they are pulled or harvested; otherwise, they will decay. If the mycelium is harmed or impaired when a mushroom is removed, the fungi or mushroom will not grow back. However, if the mycelium is unharmed, it will regrow.

Mushrooms have spores to pass on their traits to forthcoming generations and reproduce. These spores grow into new mushrooms. When the spores spread, the mushroom decays and turns into a substrate. The spores then give rise to new mushrooms. Therefore, the production of spores is only possible if the mycelium is intact. If the mycelium is not intact, the mushroom will not shed spores, and it will slowly die off.

Another factor to consider is the timing of the mushroom collection. If the mushroom cap is plucked before the spores are released, the mushroom will not regrow. However, if the mushroom is removed after it has spread its spores, new mushrooms will grow in the same location.

Harvesting mushrooms doesn't kill them

Mushrooms are the fruiting bodies of a much larger organism that lives underground. Therefore, harvesting mushrooms does not kill them. Mushrooms have a 1-2 week window of life when they sprout to when they are dead. However, by cutting and storing a button mushroom, you may be able to extend its functional lifespan.

Oyster mushrooms, for example, should be harvested when the caps begin to uncurl and flatten, but before they become too flat. The edges of the caps should still be slightly curled under when harvested to limit the number of spores they release. Oyster mushrooms grow very fast, so the difference between harvesting too late or too early is often only a few hours.

Shiitake mushrooms, on the other hand, can be harvested at any time during their growth, regardless of size. To determine if shiitake mushrooms are ready for harvest, check if the partial veil has broken, exposing the gills.

When done responsibly, mushroom picking does not adversely impact local ecosystems. It is important to avoid damaging or killing native plant species while interacting with the forest.

Mushroom poisoning can be deadly

Mushrooms are a type of fungus, and while many varieties are edible, some are poisonous and can even cause death. There is no reliable home test to distinguish between edible and poisonous mushrooms. Therefore, it is recommended to only eat mushrooms bought from a reputable source, such as a supermarket or greengrocer. If you suspect that you or your child may have eaten a poisonous mushroom, do not wait for symptoms to occur. Seek immediate medical attention by contacting a poison control centre.

Mushroom poisoning can lead to various symptoms, from mild gastrointestinal upset to severe organ failure and death. The symptoms and their severity depend on the type of mushroom and the specific toxins it contains. Some mushrooms, like the Death Cap (Amanita phalloides), are extremely toxic and can cause liver and kidney failure, with death occurring within 48 hours of ingestion. Other mushrooms with similar effects include Galerina, Lepiota, and Conocybe species. In addition, some mushrooms can cause neurological symptoms, such as seizures, while others may cause hallucinations due to the presence of psilocybin.

It is important to note that the shape of a mushroom's cap is not an indicator of its toxicity. Proper caution should be exercised when identifying wild mushrooms, and it is best to consult a mushroom expert (mycologist) if you are unsure about the safety of a particular mushroom. The treatment for mushroom poisoning is typically guided by symptoms and may include the administration of activated charcoal to limit toxin absorption.

The risk of mushroom poisoning can be mitigated by taking some precautionary measures. Firstly, refrain from consuming wild mushrooms unless you are absolutely certain of their edibility. Secondly, be cautious when allowing young children to play in areas with wild mushrooms, as they may accidentally ingest them. Finally, if you intend to consume wild mushrooms, properly educate yourself on mushroom identification and always verify the edibility of a mushroom before consuming it.

Cooking, peeling, drying, or soaking mushrooms does not make them edible

Mushrooms are a type of fungus with a short lifespan, typically only living for 1-2 weeks after sprouting. The death of a mushroom is not marked by it being picked, packaged, refrigerated, sliced, or even digested. Instead, a mushroom dies when it matures to the point that it can no longer regrow the mycelium it originated from. This varies across species due to the unique chemistry of each type of mushroom.

While some mushrooms are harvested as buttons, others are harvested at maturity or when ripened. Some mushrooms are foul-tasting as buttons but improve with age, while others are the opposite. Certain mushrooms are even harvested specifically for their foul-tasting compounds for recreational use.

Poisonous mushrooms can be extremely dangerous, with some varieties containing enough poison to kill an average-sized adult. It is important to note that cooking, peeling, drying, or soaking a mushroom does not make it edible. The only way to ensure the safety of wild mushrooms is to have them identified by a mushroom expert (mycologist). Unless you are an expert, do not consume wild mushrooms. There is no reliable home test to distinguish between edible and poisonous mushrooms.

Symptoms of mushroom poisoning include severe gastrointestinal issues such as abdominal pain, nausea, vomiting, and diarrhoea. If you suspect mushroom poisoning, seek immediate medical attention. Do not wait for symptoms to occur, as consuming poisonous mushrooms can lead to collapse, respiratory failure, seizures, or anaphylactic shock.

Mushrooms can cause fatal poisoning in pets

Mushrooms are curious organisms that do not conform to the traditional concept of death. Unlike animal cells, their specialised tissues, called mycelium, do not die instantly when severed or damaged. Instead, a mushroom's death is marked by its maturation, when it loses the ability to regrow its mycelium.

While mushrooms themselves do not always die in the traditional sense, they can cause fatal poisoning in pets. The toxicity of mushrooms varies greatly, and even a single mushroom of certain species can be lethal. The Amanita species, commonly known as the death cap or death angel, is one of the deadliest mushrooms, causing liver failure in pets. Other toxic mushrooms include the Devil's bolete, which leads to severe gastrointestinal issues, and the Galerina and Lepiota species, which have been associated with fatal poisonings.

Symptoms of mushroom poisoning in pets can include vomiting, diarrhoea, tremors, seizures, and liver and kidney failure. In some cases, symptoms may appear within 15 to 30 minutes of ingestion, while in other cases, they may be delayed by up to 24 hours. It is crucial to seek immediate veterinary care if your pet is suspected of ingesting any wild mushrooms, as prompt treatment is critical to a successful outcome.

Veterinarians may employ various methods to minimise toxin absorption and protect the pet's vital organs. This includes inducing vomiting, administering activated charcoal to bind with the toxins, and performing gastric lavage to remove any remaining mushrooms from the stomach. Intravenous fluids are also given to combat dehydration and flush out the toxins.

To prevent mushroom poisoning in pets, it is essential to regularly check your backyard and remove any mushrooms that may pose a threat. When walking or hiking with your pet, keep them on a leash in areas where mushrooms may be present. By taking proactive measures and seeking immediate veterinary care in the event of mushroom ingestion, you can help protect your furry friend from the potentially fatal consequences of mushroom poisoning.
