Four people have died and three others have required liver transplants after eating the aptly named death cap mushroom that is proliferating in California following a rainy winter.

The California Department of Public Health is urging people to avoid mushroom foraging altogether this year because death cap mushrooms are easily confused with safe, edible varieties.

Since Nov. 18 there have been more than three dozen cases of death cap poisonings reported, including the four deaths and three liver transplants, according to the health department. Many who sought medical attention suffered from rapidly evolving acute liver injury and liver failure. Several patients required admission to an intensive care unit. They have ranged in age from 19 months to 67 years old.

The death cap is one of the most poisonous mushrooms in the world and is part of a small group of mushrooms containing amatoxins, which are highly potent compounds causing 90% of fatal mushroom poisonings globally. They are in city parks and in forests, often under oak trees.

19 months! Who feeds foraged mushrooms to an infant?!

    I live in the PNW, where there are several varieties of poisonous mushrooms, including death caps. Apparently people can safely forage for mushrooms - but it scares the crap out of me because of the exact scenario in this article.

    Foraging for mushrooms is one of those activities where the risks far outweigh the rewards, at least to me.

    Especially when you can cultivate most of the good ones yourself

    You can’t cultivate morels or chanterelles. I don’t think you can cultivate porcini? I don’t think there are deadly look alikes for those varieties but folks really need to consult experts if they’re gonna dabble in mushroom hunting.

    I think people get into trouble hunting for psychedelics since 1) many of the experts (like at mushroom hunting clubs) won’t help with anything illegal and 2) many of the fun mushrooms are little brown mushrooms which are pretty difficult to identify correctly.

    TLDR: If you’re looking to make risotto, you can probably learn enough to do it safely. If you’re looking to expand your mind, just buy spores from a reputable source and grow.

    I think morels can be cultivated by now to some extent, but seemingly not yet in any significant quantities. Porcinis cannot not be cultivated and are one of the easiest mushrooms to learn to safely forage. Hunting for psychadelics is risky and in some regions very disappointing. In europe for example there arent many true psychadelic mushrooms that grow in the wild (psilocybe). I have only seen two kinds here but i dont pay to much attention to them either. Problematic when foraging them wild, if one wants to consume them, is also that the content of the psychadelic substance may vary quite significantly making it hard to judge the dosage. And yes they are not as easy to safely identifiy as many common 'choice edible' mushrooms. But these are not the main source of poison cases. The main souce are still the destroying angel and such that are mistaken for some agaricus like the ones one can buy in every supermarket. Of course if one approaches this seriously learning the basics for 'choice edibles' isn't to hard, the problem is that some do forage without learning the basics.

    Damn. People are getting killed over what they thought was a $2/lb button mushroom? I can see making the effort to hunt and properly identify for a $34/lb gourmet. But a bog standard cremini? Madness.

    The are morel lookalikes that are toxic. I think they are easy to distinguish if you know what you are doing, but I don't know what I'm doing so I don't forage mushrooms at all

    Yeah the reward is you get some mushrooms. It's not like they're expensive to buy

    For what it’s worth, the poisonings are almost always children or people who are familiar with safe mushrooms in their home country that look just like the death cap, not local knowledgeable foragers.

    That said I don’t eat foraged mushrooms either, even though it’s probably safe, because you only get one liver.

    I forage mushrooms. I think there is both a healthy fear and an overreaction to how dangerous it really is. A novice can forage for something like chicken of the woods because it is an obvious species that has no deadly lookalikes. However there are mushrooms even I still avoid despite knowing exactly what they are because they have poisonous lookalikes.

    What's really surprising is people seem to think foraging plants to be safer despite there being plants with edible lookalikes like poison hemlock that can kill in minutes.

    In the end, a little bit of practice, focus, and understanding safety, mushroom foraging, and plant foraging, is actually much less dangerous than one would imagine. Still, if you don't know what you are doing you should never eat a mushroom or plant that you aren't 100% certain is what it is. Never munch on a hunch.

    Who the fuck is giving a one year old child some mushroom they found in the woods?

    So unsettling that some mushrooms are delicious in a risotto or omelette and others will fucking murder you.

    All of those involved in this were people who used to forage in their respective home countries. They knew regional edible species before moving to California, as a result they identified what they thought was edible, but as it happens was deadly poisonous.

    Please don't come away with the opinion that you cannot identify mushrooms or that the process is somehow mysterious, that's not the case. If you are considering getting into mushroom identification, please get in touch with your local mycological society: https://namyco.org/ as they are an excellent resource and it's a whole lot of fun. Don't rely on anyting a "AI" will provide you, either forward or backward. Don't ever just guess or YOLO it. When in doubt, throw it out.

    Articles like this come out every time these unfortunate events occur, and since mushrooms are culturally stigmatized, the facts of the events are brushed over and uneducated attitudes and stigmas are spread and continue fester--which is a shame as it provoakes a very fearful attitude towards mushrooms in general.

    They're about a billion different forms of mushroom and they all look mostly the same why would anyone risk it?

    Real talk! I studied mycology, and the only culinary mushroom I feel comfortable identifying is morels.

    Are these linked to "AI identification"?

    Not likely, all the victims were migrants who had a practice of forraging where they grew up natively. I've read about cases like this across the country on either coast of the US.

    However, there seems to be a spike, either due to the rains in California or perhaps another reason--not going to go as far as plaming 'AI' identification. I certainly wouldn't trust "AI" to do that job.

    The California health department is providing video and documentation in order to help people identify the "Death Cap" mushroom in multiple languages:

    Goddamn wtf mushroom people is it really worth the risk?

    It’s not a risk if you know what you are doing. Then again I don’t forage for mushrooms that look like phalloides, besporigeras or marginatas. I stick with ones that are easily identifiable like Lions Mane, Oyster, Lobster, chanterelles, morels, porcinis, matsutakes and the like.

    It gets you outdoors and learning your land, even if you are just observing/documenting and not collecting for food. That said, I don’t get the people that roll the dice with iffy picks or trusting roadside vendors without experience. They are crazy. Amatoxin death sounds gnarly.
