There are lots of delicious edible mushrooms<\/a> that grow across North America. There are even more poisonous mushrooms that foragers should leave alone. When it comes to safe, successful foraging, knowing which mushrooms to avoid is just as important as knowing which mushrooms to pick, if not moreso. Correct wild mushroom identification makes the difference between a tasty pasta dish and a trip to the emergency room.\u00a0<\/p>\n Foragers aren\u2019t the only ones who should heed this advice. Parents and dog owners should also be aware of what mushroom species they might encounter on a walk or in the grouse woods.<\/p>\n Trent Blizzard, founder of Modern Forager<\/a> and president of the North American Mycological Association<\/a>, provides insight on a few high-profile poisonous mushroom species. He explains how to identify them, what symptoms they can cause, and why foragers should never take a risk on an unidentified LBM, or little brown mushroom.<\/p>\n Before diving into these different species of mushrooms to avoid, it\u2019s important to understand what separates inedible, toxic, and deadly mushrooms. The three categories should not be confused.<\/p>\n \u201cThere are only a couple mushrooms we would call \u2018deadly,\u2019\u201d which I think is an interesting distinction,\u201d says Blizzard, noting that \u2018deadly\u2019 mushrooms can kill humans. \u201cThere are inedible mushrooms that would taste horrible and make your stomach hurt. Then, there are a lot of mushrooms that would make you very sick but won\u2019t kill you, and you could call those toxic but not deadly.\u201d\u00a0<\/p>\n Blizzard notes that certain hallucinogenic wild mushrooms, which contain psilocybin and are ingested for recreational or medicinal purposes, can produce some of the same symptoms that other toxic mushrooms do.<\/p>\n \u201cYou might even argue that \u2026 psilocybin mushrooms that grow in the wild are toxic,\u201d he says. \u201cThey might make you pretty sick as they send you on your brain journey. So even that\u2019s a funny line.\u201d\u00a0\u00a0<\/p>\n While most poisonous mushrooms have been graced with self-explanatory nicknames over the years, the death cap mushroom might have the most foreboding alias of them all. Formally known as Amanita phalloides, <\/em>the death cap kills<\/a> one to three of every 10 people who eat it. Therefore, the death cap mushroom can definitely be considered deadly.<\/p>\n These mushrooms are generally light in color, making them easy to spot in most environments. Their pale yellow, green, or white cap and skirt around the upper part of the white stem are telltale signs of their identity. Immature death caps are shorter and more stout, and the edges of the cap still fold down around the stem. They might even be partially or fully attached to the stem, like a closed umbrella. Mature death caps have wide, flat caps that round down at the edges, more like an open umbrella.<\/p>\n Death caps are originally native to Europe, but are thought to have traveled to North America on the roots of ornamental trees, according to the Bay Area Mycological Society<\/a>. They are widespread along the Pacific Coast, from California to British Columbia<\/a>. There is a large concentration of sightings in urban Vancouver. The death cap\u2019s ability to flourish in urban and suburban environments is one of its deadliest traits, since more adults, children, and pets are likely to encounter them there.<\/p>\n You might recognize the fly agaric mushroom from your favorite childhood fairytale or from the cartoon world of the Mario Brothers. The stereotypical toadstool of Amanita muscaria<\/em> stands out in the woods thanks to its bright red cap with white spots and a white stem. These mushrooms are considered toxic and will make you sick, but they aren\u2019t likely to kill you.<\/p>\n Fly agaric mushrooms are also psychoactive, meaning they cause hallucinations if consumed. For this reason, they\u2019ve been used in a variety of shamanistic rituals for thousands of years. Shamans used to collect fly agaric mushrooms during the winter solstice in northern Europe and Asia while wearing red suits with white trim and black boots. They would bring the mushrooms back to their villages for use in rituals. These shamans are thought to be the original inspiration<\/a> for the modern Santa Claus, his red and white suit, and his trips down our chimneys with sacks full of presents.<\/p>\n \u201cAmanita muscaria<\/em> has traditionally been marked as a toxic mushroom. But there\u2019s a ton of lore and symbolism around it,\u201d Blizzard confirms. \u201cThat mushroom has played a pretty big role in various cultures around the world.\u201d<\/p>\n Fly agaric mushrooms are one of the easiest wild mushroom species in the world to identify. Few mushrooms share the same scarlet hue that makes them so visible in green and brown underbrush. Their white bumps also create a distinct, eye-catching pattern.\u00a0<\/p>\n Under the cap, the fly agaric mushroom has white or cream-colored gills that don\u2019t attach to the stem. Similar to the death cap, these poisonous mushrooms tend to have a light-colored skirt around the stem, as well. They grow up from a cup that is often buried underground, where it attaches to a mycorrhizal network that sustains other mushrooms and tree roots in the area.\u00a0<\/p>\n These poisonous mushrooms exist around the world, but are native to the Northern Hemisphere in Europe and Asia specifically. They prefer birch and conifer forests and usually pop up in late summer and early fall. Much like the death cap, these mushrooms have been introduced in North America and the Southern Hemisphere on relocated trees. A few subspecies of fly agaric exist in the United States. The classic red mushroom is more popular on the West Coast, while a yellow subspecies<\/a> (identical to the red fly agaric but with a yellow-to-orange cap) exists on the East Coast.\u00a0<\/p>\n Another Amanita<\/em> species with a scary name, the destroying angel mushroom (also known as the death angel) definitely belongs on the list of poisonous mushrooms to know and avoid. There are two subspecies of destroying angel (Amanita virosa <\/em>and Amanita bisporigera<\/em>), <\/em>which means foragers have a slightly wider range of characteristics to look for. But ingesting either subspecies will first cause\u00a0 extreme intestinal distress<\/a> marked by nausea, vomiting, and diarrhea before causing liver and kidney damage that could result in both organs failing. Organ damage often occurs the day after ingestion and death can occur within seven days<\/a>.<\/p>\n \u201cThe destroying angel is just a beautiful mushroom,\u201d Blizzard says. \u201cIt\u2019s white and very nice to look at, but it will kill you.\u201d\u00a0\u00a0<\/p>\n This poisonous mushroom tends to be taller and skinnier than the death cap and the fly agaric. Its flesh is a bright, clean, white color from cap to stem, giving the mushroom its namesake angelic appearance. The underside of the cap is covered in gills and a skirt surrounds the stem underneath the cap. It also grows upward from a cup-shaped base, which is often buried underground and attached to the bottom end of the stem.<\/p>\n The Amanita virosa <\/em>subspecies is native to Europe, where it occurs in mixed hardwood forests and grassy fields. This subspecies does not exist in North America, but A. bisporigera<\/em> does, where it\u2019s also known as the Eastern North American destroying angel. As its name indicates, its distribution<\/a> is limited to the eastern half of the continent and stretches from Canada to Mexico. Both subspecies prefer the same types of habitat with spotty sunlight and pop up in late summer and early fall.<\/p>\n This poisonous mushroom is known as the green-spored parasol, or the false parasol. Its common nickname, \u201cthe vomiter,\u201d makes clear the unpleasant fate that awaits any forager who eats a Chlorophyllum molybdites<\/em>. Ingesting this mushroom won\u2019t kill you, but the variety of gruesome side effects ranging from extreme stomach irritation to bloody diarrhea might make you wish it had.<\/p>\n \u201cThis pretty little white mushroom grows in the most beautiful grass in a park. People just think \u2018Aw, that\u2019s so pretty, I\u2019m going to eat it,\u2019 or children or dogs do,\u201d Blizzard says. \u201cBut it\u2019s called \u2018the vomiter\u2019 for a reason. I think it\u2019s one of the more common problem mushrooms.\u201d<\/p>\n The vomiter mushroom has the same general shape as the death cap, fly agaric, and destroying angel: its stem is tall and thin with a skirt that sits just under the cap. This cap ranges from rounded downward to wide and flat, depending on the mushroom\u2019s age. The cap might also have shriveled remnants of a brown peel marking it, exposing a lighter color underneath.\u00a0<\/p>\n Light tan-green gills under a cream-colored cap give this mushroom its unique name. The green tinge comes from the microscopic spores that live in the gills, which are naturally green. In fact, if you place the cap of a green-spored parasol on a white piece of paper, gill side-down for a few hours, it will leave a green spore print behind. Just be sure to use gloves if you choose to handle any poisonous mushroom and wash your hands after you\u2019re done.\u00a0<\/p>\n Lots of poisonous mushrooms prefer mixed hardwood forests and more northerly latitudes. But the green-spored parasol pops up most commonly in more tropical parts of North, Central, and South America. They\u2019re also common in Central Africa and the Pacific Islands.\u00a0<\/p>\n Homeowners in the Lower Midwest and Southeast, from Missouri<\/a> to North Carolina<\/a> to Florida<\/a>, are used to finding these poisonous mushrooms growing in their lawns. They can show up any time from April to November, as long as the climate is wet and warm.<\/p>\n The infamous little brown mushroom, or \u201cLBM,\u201d isn\u2019t one particular species of mushroom. Instead, the acronym stands for hundreds of species of small, unidentifiable mushrooms that don\u2019t have any major distinguishing features and therefore should be left alone. Some might be deadly, while others might barely harm you. Others still might send you on a wild psychedelic trip that could have long-lasting negative effects. The point is that little brown mushrooms<\/a> are unknown to even the most expert foragers, says Blizzard, and therefore aren\u2019t worth the risk.\u00a0\u00a0<\/p>\n LBMs are easy to identify. If you see a small brown mushroom growing in a lawn, meadow, or in the woods, and you have no clue what it is, congratulations\u2014you found one. It could be a deadly Galerina<\/a>\u2014which has the same toxins as the death cap, fly agaric, and destroying angel\u2014or a less toxic but still inedible lawnmower\u2019s mushroom<\/a>. There\u2019s no good reason to take the chance on harvesting and eating these fungi.<\/p>\n If you come across a little brown mushroom and are curious about it, snap a few photos of the mushroom\u2019s cap, stem, and underside for further research. If the mushroom is growing in your yard or on a public trail, put gloves on and harvest one to take a spore print<\/a>. Use paper that contrasts the color of the underside\u2014if the gills are really dark, set the cap gill-side-down on white paper. If they\u2019re really light or white, use black paper. Cover the cap with an upside-down drinking glass to protect it (and your counter) for up to 24 hours while it spills its spores on the paper underneath. Spore prints are one trusted method among expert mycologists for identifying mushrooms, or at least for ruling out certain species.<\/p>\n LBMs pop up all around the world in a variety of environments. They can grow from early spring to late fall. As is typical with most wild mushroom species, they\u2019re more likely to grow in moist environments and during wetter times of the year. If you keep your eyes peeled the next time you\u2019re outside, it shouldn\u2019t be too hard to find one.\u00a0<\/p>\n An afternoon of foraging, preparing, and cooking wild mushrooms can turn into an evening in a hospital bed if done carelessly. The first step to being a responsible forager is knowing what mushroom species shouldn\u2019t end up on your plate. The rule of thumb is that if you can\u2019t identify a mushroom with 100 percent confidence, you absolutely shouldn\u2019t eat it. Being able to identify poisonous mushrooms with confidence is a crucial skill for all foragers.\u00a0<\/p>\n \u201cWhen you consider the range from edible to inedible to toxic to [deadly], there\u2019s no simple little rule of thumb,\u201d Blizzard says. \u201cAnd even if you did, that rule would be very geographic in nature. That rule could get you sick in California but it could work fine in Virginia.\u201d<\/p>\nPoisonous Mushrooms: Inedible vs. Toxic vs. Deadly<\/h2>\n
