Short Stuff: Death Cap Mushroom

This is an iHeart podcast.

Living with a rare autoimmune condition comes with challenges, but also incredible strength, especially for those living with conditions like myasthenia gravis or MG and chronic inflammatory demyelinating polyneuropathy, otherwise known as CIDP.

Finding empowerment in the community is critical.

Untold Stories, Life with a Severe Autoimmune Condition, a Ruby Studio production in partnership with Argenix, explores people discovering strength in the most unexpected places.

Hey, and welcome to the short stuff.

Josh here, Chuck here, Jerry, no here.

Dave, no here.

That's okay, because like I said, it's a short stuff.

Good evening, everyone.

We are Death Cap Mushroom.

Yeah, that's a great one.

It's a metal band, right?

For sure.

Even just Death Cap would work, too.

Death Cap for Cutie even would be cool.

Oh, man.

I like those guys.

Yeah, they're great.

Did you like Postal Service?

I love the Postal Service more than Death Cap.

It's just the one dude from Death Cap, right?

Isn't it his Solo project?

Not Solo.

Ben Gibbard, he linked up with someone else.

It's like him and another guy.

I can't remember the other guy, but man, I love that Postal Service record.

Okay, good, good.

I'm glad you did.

I'm glad they made it then.

Me too.

So we're not talking about Death Cap for Cutie.

We're talking about Death cap Cap mushrooms not for you, I think is the main message here.

Not for cuties or anyone.

No.

And the reason they call it death cap mushroom is because it can kill you if you eat it.

It's not necessarily an automatic death sentence, but apparently the fatality rate from eating this mushroom is 10 to 15 percent

of people who eat it die.

That's that's in this House of Works article, they were like, you know, that's pretty low.

I'm like, not to me.

No, that's, I mean, that's really high.

Look at white button mushrooms, buddy.

It's almost like zero.

And I think the people who do die from eating white button mushrooms ate too many at once and choked to death.

This is why I don't eat mushrooms at all.

Oh, you don't, huh?

No, it's a texture thing.

They're too slimy for me.

I've tried.

Oh, no.

You got to wash the slime off.

And I'm not expecting you to actually try this, but I know exactly what you're talking about.

You wash the slime off, you dry it, you lick the top of it, put some salt on it, and eat it raw.

And it's got a nice, sturdy crunch almost to it.

And I love those.

You know what's funny?

I don't think I've ever mentioned not liking eating something where you didn't say, No, no, no, you're just doing it wrong.

I like eating everything.

All right.

So there was an outbreak in 2016 in the Bay Area of San Francisco where 14 people consumed,

well, the death cat mushroom.

Yeah.

Got really, really sick.

One very sad story of a child suffered permanent neurological damage.

And the question is, like, how did these things get here?

Because they did not originate here.

That's one of the questions.

Are you setting me up to answer it?

Well, sure.

Do you have an answer?

Because I do.

I have a general answer.

Apparently, so it's an ectomycorrhizal fungus that engages in symbiotic relationships, mutualism, with specific kinds of trees.

And in Europe, they're typically beech trees or oak trees, and it lives in the roots,

the main part of the fungus.

And it trades nitrogen that the mushroom draws from the soil to the oak or the beech tree in exchange for sugars and water and carbon.

And they do this by basically connecting their roots to the tree roots.

And everybody's happy until you come along and eat one of the death caps.

Yeah, I think we did a whole episode on mutualism, didn't we?

Surely.

Or Or symbiosis or something else.

Yeah.

But I didn't answer your question.

The answer seems to be that somebody imported a tree from Europe at some point that had a death cap mushroom, mycorrhizae, in its roots.

And surprise, death cap mushrooms are in North America.

Yeah, and they know that it wasn't a native species because, you know, that could be possible that there's just like a California, North America version.

Sure.

But it would be genetically different somehow.

But the ones that we have over here are exactly the same.

It's the same mushroom.

I think the first known sightings were in 1938 at the Del Monte Hotel in California.

There's a lot of these in California.

And then

five, six, seven, eight years later at the Cal Berkeley campus.

And now they're kind of all over the place.

They're on the East Coast.

They live in the pines and the East Coast.

But those oaks on the West Coast, all the way up to Vancouver, I believe, but they've also found them outside of Europe in Western Russia, southern Scandinavian coasts, and North Africa.

Yeah.

They go, I think also on the west coast of the United States, they grow all the way down to L.A.

County,

which is how Cheech Marin accidentally ate one.

Oh, did he really?

Or is that a joke?

That is joke.

I'm sorry.

I'm so mad at you.

You could have said, like, I know it was.

You have to say it really weird like that.

Seems so likely that Cheech Marin might have accidentally eaten one of these.

I think he kind of went straight with that whole Nash Bridges gig that he got.

And Tony Chong is like, no, man, I still eat whatever I find on the ground.

Speaking of Nash Bridges,

maybe I shouldn't say this.

I'll tell y'all fair.

Oh, I can't wait.

Is it about Don Johnson?

Yeah, it is.

All right.

So, should we take a break or should we talk a little bit more about it?

Let's take a break.

All right.

We'll be right back with more on this Death Cap mushroom.

Let's talk about something you probably haven't thought about.

Your couch.

Yeah, that thing you nap on, eat on, cry on.

Turns out that most silfas are basically bacteria playgrounds.

It's true.

We looked it up.

It's not good.

But Anibay changes that.

It's washable, like fully washable.

Take the covers off, throw them in the machine, boom, clean.

Also, it's actually affordable, which is surprisingly rare.

So yeah, if you're gonna sit on something every day, maybe don't make it a biohazard.

And here's the kicker.

It's not just practical, it's affordable.

Starting at just $699, you can make your sofa as clean as it is comfy.

Right now, you can even get up to 60% off your Anibay sofa.

Because let's be real, you deserve better than a germ factory for a place to rest your head.

Check out washablesofas.com now and give your couch the upgrade it's begging for.

That's washable sofas.com.

All right, we're back, and this is something I don't fully understand, but the Def Cat mushroom is an invasive species in California where it grows in very beautiful woodlands and forests.

It is not considered such on the East Coast, where it grows in more urban settings, like urban parks, but it still could be invasive.

Like, I don't understand what the diff is.

It's very easily contained in an urban area.

You've got your park, but then, you know, you say like, hey, mushroom, try to

spread

from this park.

Yeah, deal with this sidewalk, then the street, then the sidewalk, then a building, then another sidewalk, then a street, then a sidewalk, then a sidewalk, then a sidewalk, then a sidewalk.

And the mushroom goes, okay, fine, I'll just stay here.

All right.

So I guess I just didn't fully.

Yeah, I guess I didn't fully understand what invasive meant.

I thought invasive just meant if it was there and not great for the area.

I didn't mean it had to be like super widespread.

I didn't either, but that's what I took from this description of it.

So that's my take, I should say.

That's not like the.

I thought that was a quote.

It was of Ann Pringle, the Letters and Science Rubenstein Professor of Botany and Bacteriology at the University of Madison, Wisconsin.

Wow.

Look at you.

Yeah, we should say shout out to How Stuff Works for helping us with this article by writing it.

And they interviewed Professor Pringle about this, and she was very helpful.

Yeah.

There's a couple of toxins when it comes to the death cap.

One of them is a phallotoxin.

And you're talking, you know, what you would expect, dehydration, diarrhea, vomiting, nausea, but eventually electrolyte imbalances and kidney damage.

But the really bad booger in there is amatoxin, and that will stop cell function.

It targets the transcription of RNA by RNA polymerase 2, which we've talked about before

and that that basically causes cell death.

It prevents the cell from making the proteins and cell components that it needs to be a cell.

Right.

So that's always bad.

And apparently it goes very quickly to your liver and just starts destroying your liver.

And apparently people go to the emergency room sick with sick on basically after eating a death cat mushroom will find that the doctors want to give give them a liver transplant plant if one is available.

Oh, wow.

That's how bad it can get.

And one of the reasons why it can get so bad is because after the initial like nausea and vomiting and horrible, like, I shouldn't have eaten that mushroom that I found in that field sensation, it goes away.

And you think that you're fine, but actually, in reality, that amatoxin

is just destroying your body.

And then by the time you start to feel those effects, you're in really big trouble.

isn't liver one of the the longer waits or am i making that up longer waits yeah wait w-a-i-t-s for uh transplant i i don't know i know i don't think so because you can um cut off like a chunk of your liver and donate it because i don't know if it grows back or else it just a little bit can can perform a lot of function one of those

kidneys no i don't think i don't think so i think it's liver so we we got

all the organs are readily available right For transplanting?

For sure.

I mean, it's so easy to get when you just walk in and they try to give you two livers most of the time.

I could have said, maybe this is a while ago.

I could have sworn I read reports of like people dying on the liver transplant list.

Oh, I believe it, but I don't think that, I don't think liver is the least available.

Okay, I got you.

But I could be wrong, but yeah, I think everybody dies on the organ transplant list waiting.

Or I should say not everybody on the list dies, but I'm saying for any organ, there are people dying on the wait list.

I got you.

Yeah, boy, that's a nice correction.

So the takeaway from this is don't eat the death cap mushroom at all.

You need to, and if you're a forager, you really got to know what you're doing.

You shouldn't be like, hey, I saw this on Top Chef.

Like, I can go out in the woods and just pick stuff and eat it.

You got to be really familiar with the fungi

where you are.

And if you aren't, just don't try it.

Don't risk it.

It's not worth it.

No, I think we should issue a general COA for us here.

Don't, even if you think you are familiar with your local mushrooms, don't try it.

We are not telling you under any circumstances to go try this.

Okay.

I think foraging is wonderful, but

so I'm not going to say that personally.

But

you're welcome to.

Just know what you're doing.

Tort reform now.

There are all kinds of resources if you are interested in stuff like that that can very clearly tell you

what's safe and what isn't.

But you should still take a buddy who's done it before, I think.

You can identify, according to Dr.

Pringle,

who can't eat just one.

It has olivaceous with coloring with green tinge, and a mature death cap has

brown striations on the cap.

And don't forget fairy rings around the stem, which

who can forget the fairy rings.

Right.

It goes without saying that that's just a bunch of fairies forming a circle by holding hands.

Yeah.

So I saw one of the things, Chuck, about this.

The reason why people eat these is because they taste good.

Oh, interesting.

So, people are caught by surprise when all of a sudden they start puking because the fact that it tasted good, I think, indicated to them that this is fine to eat.

Well, you know who's never going to get sick by eating a bad mushroom?

I do.

And has two thumbs and is podcasting with you right now?

I do.

This guy right here.

Oh, that's not who I was going to say.

Oh, Cheech Marin.

You got anything else?

I got nothing else.

Short stuff is out.
