The Death Cap Mushroom Is Spreading Across the US 274

Hugh Pickens DOT Com writes "Discovery News reports that the death cap mushroom is now an invasive species on every continent except Antarctica. It is spreading along the East and West Coasts of the U.S. and appears to be moving south into Mexico. 'When someone eats Amanita phalloides, she typically won't experience symptoms for at least six and sometimes as many as 24 hours,' says Cat Adams. 'Eventually she'll suffer from abdominal cramps, vomiting, and severely dehydrating diarrhea. This delay means her symptoms might not be associated with mushrooms, and she may be diagnosed with a more benign illness like stomach flu. To make matters worse, if the patient is somewhat hydrated, her symptoms may lessen and she will enter the so-called honeymoon phase.' Without proper, prompt treatment, the victim can experience rapid organ failure, coma, and death. But good news is on the way. S. Todd Mitchell of Dominican Hospital in Santa Cruz, California has treated more than 60 patients with a drug derived from milk thistle. The patients who have started the drug on time (within 96 hours of ingesting the mushroom) and who have still had kidney function intact have all survived. 'When administered intravenously, the compound sits on and blocks the receptors that bring amatoxin into the liver, thus corralling the amatoxins into the blood stream so the kidneys can expel them faster,' says Adams. Still, Mitchell cautions against the 'regular look"'of deadly mushrooms. 'They smell very good and when they're cooked, many patients have described them as the most delicious mushrooms they've ever eaten.'"

      An interesting evolutionary point, did the death cap evolve as toxic because it was so tasty, that only the toxic variety survived as the rest where eaten. In commercial terms would the death cap be an ideal mushroom to grow and selectively breed to eliminate the toxicity, being one of the tastiest varieties.

    Is this hype because it is finding its way into the food supply in stores either via getting into commercial operations accidentally or being picked and sold as something else by wild collectors, or is it just journalistic pomp? Because, as somebody who regularly photographs fungi while out photographing native orchids, I'm willing to bet only a very small percentage of the population would ever even consider eating a wild mushroom. Even 90+ percent of my hiking buddies, all of them reasonably good at plant and fungus IDs, would never consider taking that risk unless it was something very expensive to just buy, like morels.

        True. I have a Chinese friend whose parents collect napkins. Thousands and thousands of napkins. They are also of that age group. I suspect they fear running out of napkins. Many of my older Polish family members, especially those born in Poland between say, 1938-1989, displayed similar behavior...presumably for similar albeit somewhat less severe reasons.

        Oh great, so we have that to look forward to, as our very own cultural revolution proceeds ...

      • It isn't necessarily about frugality. There are many easily identified mushrooms that can grow in your yard that are quite delicious. Shaggy manes, oyster mushrooms, various boletes, morels, and chanterelles are all delicious mushrooms I've found in yards and eaten. If you're so inclined, you can easily grow your own [fieldforest.net].
      • This may have little to do with the Cultural Revolution. Picking wild mushrooms plays a much larger role in some cultures.

      I should clarify...I mean in most of North America. Granted, certain immigrant groups may display a greater predilection for mushroom collecting, and I know it is a bigger deal in the Pacific Northwest of the US along with in Europe, but still, in NA it isn't a HUGE pastime.

    So, is there such a think as Xtreme eating (like extreme sports?)

    If the people who ate them " described them as the most delicious mushrooms they've ever eaten.'" have all survived once they took the antidote, would other people consider eating this mushroom KNOWING that they were putting their life at risk (assuming they had access to the antidote)?

    I mean is this akin to eating the "Fugu" fish (which I have!) where, for some, part of the attraction of the food is the possibility that you might die?

    Are there other foods which are (potentially?) dangerous or deadly but are so tasty that it is worth the risk?

      It isn't worth the risk. Death caps inhibit a crucial part of cell metabolism, RNA transcription. It's interesting that they don't kill themselves. People usually die of liver failure since that's where the poison ends up (the diarrhea is of course also a sign of a large number of cell deaths, but those cells are more expendable).

      Nicely tasting, absolutely deadly poisonous mushrooms with wide specificity but a large time-delay (about a week). Good for wiping out major parts of a herd. My guess is that it's due to their symbiosis with hardwood trees: gives some protection to those slow-growing trees from getting stripped of their bark by deer and other planteaters.

      A single mushroom is enough to kill a person. Even with "antidote", you will do more damage to your liver and other organs than 20 years of heavy drinking.

      You cannot compare this to Fugu since properly prepared, the meat of the fish will not cause any damage.

      If the people who ate them " described them as the most delicious mushrooms they've ever eaten.'"

      In most of the cases, the expression would change to: "the most delicious mushrooms they'll ever eat".
      You see, a human body has only one liver.

    • I read a story about a man who ate death caps and survived. He said they were unexpectedly bland. Fugu is pretty bland, too, and expensive. I went to the cheapest place I could find, $45 per person...which of course means they had the least-skilled chef there. Eek.
    • Yeah, actually, when I saw that, it made me want to try it.

      Then I read the article, and the article sounded like the mushrooms weren't super delicious, but rather the chef who prepared it was very good at preparing food. Further, it read like a eulogy, where you only say good things about the recently deceased. Even when they died from picking their own mushrooms.

      So I'm not sure there is widespread agreement that the mushrooms are so delicious.

    The Death Cap is something I learned as a child not to touch, and I teach my kids that too. It's pretty common where I live to learn which things in nature are edible and what to watch out for. I had the impression most people around the world had that kind of education "built in". Is that not the case in the US these days?

    • The Death Cap is something I learned as a child not to touch, and I teach my kids that too.

      Yes, but since it is spreading how would people have shown others to look out for it - and why would they bother when it's not supposed to be there?

      That's why the warning is a good thing, for people to be aware the Death Cap could be anywhere and so you should always look for distinguishing signs.

    The main reason these mushrooms are eaten is that they are misidentified as some similar looking edible species. The most frequent victims for these mushrooms are immigrants that mistake them for an edible species that they would find back where they were originally from. In the US on the west coast, that most often means immigrants from eastern Asia mistaking them for Volvariella, volavacea, commonly sold in supermarkets in cans as "Paddy Straw Mushrooms".

    As far as being deadly, their lethality depends mostly on how much of them you eat. In a very general sense, if you eat some and don't seek medical treatment, your odds of dying are around 50%. With treatment (before the milk thistle extract), the survival rate was more like 90%.

    There are lots of other mushrooms that also produce the same toxins in potentially deadly quantities. The ones that produce the most poisonings are Galerinas (especially G. marginata), since they resemble some of the hallucinogenic species of Psilocybe and can grow in the same habitats, at the same time, and even side by side with them. Lepiotas and Conocybes (Pholiotinas) can also be deadly in the same way, but don't generally resemble other mushrooms that most would want to eat.

    There are lots of safe mushrooms and groups of mushrooms that are easy to identify accurately enough to eat without significant risk. Members of the genus Amanita (the ones these deadly ones belong to) don't fall into that category, unless you're a real expert. A lot of the "experts" that are referred to as such are people that can identify a few species (or maybe a few dozen species) in the woods - not somebody we should treat as a real expert. It's a bit like calling somebody who has done a "Hello World" program in a couple languages a programming expert.

    If you want to learn enough to forage for your own wild mushrooms, you should contact a local mycological society. You can meet people who can show you how to identify some of the easier, safer mushrooms in your area.

  • Discovery News reports that the death cap mushroom is now an invasive species on every continent except Antarctica.

    So if it's invasive on every continent except Antarctica, shouldn't that mean that it is native to Antarctica? Or possibly not land-based at all?

    (Hint: it's from Europe.)

  • Death cap is a common mushroom in our region (western part of Russia and Baltics). You can find it easily in every forest but amounts vary by year. Despite the fact it is well known to any interested person, there are a few lethal cases every summer involving careless mushroom pickers. A cultural note: wild mushroom picking is considered normal everyday activity here, regardless your income and social status.
