In the case of mushrooms, reproduction involves growing fruiting bodies (the bit you see above ground) and releasing spores. Unfortunately in doing so they leave themselves vulnerable to attack! And unlike animals, they can\u2019t simply run away.<\/p>\n
They have quite a small window in which they can drop their spores, and for many species if they are eaten the spores are lost (although there are some species that spread their spores through <\/em>being eaten and pooped out). Poisons and toxins can therefore come in handy in keeping wannabe predators away. Over time animals learn what mushrooms to avoid and which are safe to eat.<\/p>\n <\/p><\/div> <\/section> Mistakes are sometimes made, however, as you will see on this list. Poisonous mushrooms can be mistaken for edible ones, to sometimes fatal effect. Read on to learn about ten of the most dangerous and deadly mushrooms (and other fungi).<\/p>\n These notorious and highly toxic mushrooms have a suitably alarming name. Found throughout Europe, particularly in oak or beech woodlands, death caps are responsible for the majority of all fatal mushroom poisonings. This is partly because, unfortunately, they resemble several edible and popularly eaten species, such as Caesar\u2019s mushroom.<\/p>\n They also, apparently, taste quite pleasant. Ingestion leads to liver failure, kidney failure, and death. Foragers be very wary! Not all death cap deaths have been accidental, however, with these mushrooms being suspected in a number of famous assassinations, including that of Roman Emperor Claudius in 54AD by his wife Agrippina.<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n A group of three closely related species that share a deadly name, destroying angels can be found in woodlands, grassy meadows, and lawns,\u00a0 across Europe and North America. Like death caps, they have a white cap and gills, and also like death caps contain amatoxins. Amatoxins are extremely toxic compounds that travel through the bloodstream and disrupt cell metabolism, consequently damaging many organs including the liver and heart. Just a small amount can lead to death \u2013 for example, that contained in as little as half a destroying angel cap.<\/p>\n \u00a0<\/p>\n Another species that shares these toxic compounds is Pholiotina rugosa<\/em>, a fairly nondescript-looking, red-brown mushroom common in the Pacific Northwest, but found in Europe, Asia and North America too. Due to their similar conical brown caps, they are sometimes mistaken for Psilocybe, <\/em>or magic mushrooms.<\/p>\n You would get much more than a bad trip with these, however.\u00a0 After about 6-24 hours after ingestion, you would experience some very nasty gastrointestinal symptoms, often initially mistaken for food poisoning, swiftly followed by liver failure and, if you are unlucky, eventual death.<\/p>\n <\/p><\/div> <\/section> This next group of poisonous mushrooms is much slower to kill you. This is a large genus of over 2000 species, only some of which are poisonous but all of which you should be wary of, due to difficulties in distinguishing them. Cortinarius rubellus<\/em> (the deadly webcap) and Cortinarius orellanus <\/em>(the fools webcap) are the ones that you really don\u2019t want to pick, however.<\/p>\n Both of these contain the mycotoxin Orellanine which affects the kidneys. This toxin takes an insidiously long time to take effect, with symptoms not appearing for up to two weeks after ingestion, by which time it is too late to do much about it \u2013 the kidney damage is already done. There is no known antidote and the primary treatment is hemodialysis. Without treatment, death occurs.<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n Galerina marginata <\/em>has garnered itself a whole slew of dastardly-sounding names. As well as the spooky autumn skullcap<\/em>, it is also known as the deadly skullcap and even funeral bell! Like many already on this list, it is packed with liver and kidney-disrupting amatoxins, and ingestion leads to severe gastrointestinal distress, organ failure, and even death if not treated swiftly.<\/p>\n As with Pholiotina rugosa <\/em>several fatal poisonings involving this little brown species are suspected to have occurred due to foragers mistaking them for hallucinogenic mushrooms. They are found throughout the Northern Hemisphere and generally grow in small clusters on or near conifer wood.<\/p>\n \u00a0<\/p>\n This jauntily named mushroom is not so alarmingly coloured or easily spotted as the fire coral is, unfortunately. Its innocuous white-brown appearance means that it is fairly easily mistaken for a few different edible species (including the edible grey knight (Tricholoma terreum<\/em>) and fairy ring champignon (Marasmius oreades<\/em>)), leading to accidental, and sometimes sadly fatal, poisonings. As these mushrooms grow in grassy areas, often these mistakes occur when people pick from their own gardens.\u00a0 In 2010 four members of the same family died after consuming dapperlings.<\/p>\n \u00a0<\/p>\n The aptly named false morel almost looks like it\u2019s designed to trick an unwary forager. With its brain-like cap and creamy white stem, it closely resembles the prized and very tasty morel mushroom. Unlike a true morel, however, the false morel contains a deadly surprise, the toxin gyromitrin. When gyromitrin is broken down in the body it becomes monomethylhydrazine, a toxic compound better known for its use as a rocket fuel! This acts on the central nervous system causing a variety of unpleasant neurological and gastrointestinal symptoms, and in severe cases can result in death.<\/p>\n \u00a0<\/p>\n Perhaps the most iconic and well known of all mushrooms is the fly agaric. This classic red and white spotted toadstool is a staple of children\u2019s picture books, works of art, garden ornaments, and even video games. They have become associated with magical creatures, fairies and gnomes in particular.<\/p>\n They do however have a darker side. These mushrooms contain several different bioactive compounds, including those both toxic and psychoactive. Though not nearly as dangerous and deadly as some on this list, historical deaths due to ingestion have been reported and they are not to be trifled with. The symptoms are unpredictable and may range from delirium and hallucinations to seizures and comas. Part of the risk involved in eating these comes from the sporadic and sometimes dangerous behaviour that it induces.<\/p>\n \u00a0<\/p>\n This common and nondescript mushroom was once widely regarded as edible once cooked and was widely eaten in Central and Eastern Europe until the 1940s. However in 1944 it was found to be responsible for the death of German mycologist Julius Sch\u00e4ffer \u2013 the only professional mycologist known to have died from fungus poisoning.<\/p>\n He had eaten a succession of meals containing roll-rims. It is now known that the mushrooms can trigger an autoimmune reaction, especially in people who have eaten them over a prolonged period of time \u2013 like the unfortunate Julius. The body attacks its own red blood cells which may lead to kidney failure, acute respiratory failure, and even death.<\/p>\n \u00a0<\/p>\n9 most poisonous mushrooms<\/h2>\n
