The Death Cap Mushroom Is Spreading Across the US

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.'"

      I actually know of only one case in my (not immediate) family that has been poisoned by mushrooms. This was because of a French friend who was visiting in Finland and was living at one of my relatives. He cooked a dinner using mushrooms he had picked. The mushrooms he picked looked very much like a mushroom, which is a delicacy in France. Unfortunately, there is a mushroom in Finland that looks quite a bit like it, but is very toxic. However, you can eat it if you cook it three times in fresh water before consumption. Someone joked during the dinner "so how many times did you cook it?" and then everyone was off to the hospital...

      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.

    "should have mentioned I mean they are easy to ID and eating unidentified fungi has always been stupid thing to do"

    "Easy to ID" is a relative term. Even experts get some fungi wrong. For example, there are poisonous species of Galerina that sometimes grow right alongside the prized hallucinogenic "Liberty Cap" mushrooms, and even experts have to take a spore print and use a microscope to tell them apart.

    As a PSA, here are two warning signs displayed by A Phalloides as in that picture on Wikipedia:

    First is the "veil" surrounding the stem just below the cap, which you can see on the larger mushroom that is setting on its side. The other is the "cup" at the bottom.

    It is important to note that neither of these are reliable indicators. Some edible species of mushrooms have one or both. Many poisonous species of mushrooms do not.

    The point is: unless you know EXACTLY what you are doing, treat those features as strong warning signs. Best not to eat any mushrooms that have them.

    Indicators and rules of thumb are a good start. However these are also very regional. There were cases of Russians who moved to north america and are mushrooms that would be safe back in Russia (based on guides such as A+B implies safe to eat).

    As noted, to be safe you really want a definitive identification. In extreme cases this requires a spore print and microscope. On the other side, in many cases you narrow it down to either a good mushroom, or one that gives some people indigestion but that's it, and then you may just take the risk and taste it.

    Foraging can be very enjoyable, and is not restricted to mushrooms, nor does it require living through a depression or the cultural revolution or any such crisis. However, it is very culture dependent, and many in north america there is a tendency to treat all unknown food as dangerous. A friend told me she was eating some wild berries in a local park with her son.

I have eaten fly agaric but that was prepping properly and flavour isn't great but I didn't eat them for that.

  13. Lots of confusion and misinformation... by Kotetsu · · Score: 4, Interesting

    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.

    So? Females are the norm, and males the exception.

    This is not so. By default each human cell is a male cell. Female cells have to be constantly refreshed into being female through hormone release.

    The way it works is that when you are born male you have something called SRY and it increases SOX9 and decreases FOXL2 which is the "opposite" part of a cell that determines which gender it is. For females it is the otherway around. However, if a female does not suppress SOX9 they will develop male characteristics (this is why you can get an XX male). The cells default option is to move back toward "maleness" and this is why after menopause women and men aren't really that different (because at a cellular level they are tending towards the same gender expressions).

Often it gets to their new place with oaks that are grown in Europe (or a place where the Death Cap grows already) and then transported somewhere else to be planted in parks and gardens.

    And yes, in Europe, there are also mushrooms that look quite similar to the Death Cap, but are edible, like the Blusher or Saffron Ringless Amanita. So people coming from Europe to California to go mushroom hunting and are messing up a Death Cap with a Blusher would have made the same mistake in Europe.
