A company grows these (and other mushrooms) in a warehouse here in Zurich to supply restaurants and grocery stores, which is probably one of the reasons these mushrooms are now found in the wild.
I "hunt" (in German you use the verb "collect/gather") mushrooms in the forests around Zurich and I haven't seen these yet. They also don't appear in my Pilzfürher app specific to Switzerland. But I have heard they are here. From pictures I've seen of them in the wild I might dismiss them from a distance because I could mix them up with two common yellow mushrooms here - one poisonous.
"Mushroom hunting" is a fairly common phrase in English, too. It appears to have the top-level title for the page about that activity, on Wikipedia, even (mushroom foraging, mushroom picking, and mushrooming are all given as alternative terms)
Plus it's the title of a song on the Cowboy Bebop soundtrack, so it has that going for it.
The German term is "Pilze sammeln" which literally translates to: collect mushrooms.
There are many dialects of the German language - where I'm from, we would use "Schwammerl suchen" ("Schwammerl" as another term for "Pilz(e)"). This literally translates to: searching for mushrooms.
A friend of mine went to a local mushroom picking course and among things they mentioned that morels are difficult to cook from fresh, because of the gastro problems. Apparently, the advice was to dry them before using in recipes.
They aren't 'difficult' to cook. They are dangerous to eat if uncooked (and thus undercooked).
While true morels themselves can be dangerous while uncooked, there are similar looking species that are both less and more dangerous.
Species of Gyromitra or "false morels" like Verpa Bohemica will commonly all be called "morels": both as an intentional cultural colloquialism or simple misidentification.
Depending on which hemisphere you live in, some Gyromitra species may be more dangerous than true morels. They can also be more dense and harder to cook thoroughly.
Most mushroom species will cause an upset stomach if undercooked. Drying is an effective way of reducing both dangerous and uncomfortable compounds. It's suggested for morels out of an abundance of caution, but it is not a necessary step.
(Note that not all compounds are destroyed! "Magic mushrooms" are famously traded dry for example!)
The advise to add an additional preparation step also increases the chance someone will notice the wrong species hiding in their ingredients. Undesirable species can have overlapping habitats and climates so its not uncommon for a careless or ignorant forager to pick the wrong thing.
Morels contain several volatile compounds which cause gastric distress. (Forgive me for not looking it up at the moment, but one of them is/was a compenent of rocket fuel, which teenage me loved.) They have to be thoroughly cooked to burn those off. Or else dried.
Specifically for soup - which is, arguably, their best use - most people won't saute morels long enough before adding liquid, so it's always best to use dried for that. Otherwise, standard, boring, dry-sautéed + butter until tender works great, and has never given me a hint of upset.
The instructor of your friend's mushroom course may have been giving maximally-cautious advice, rather than trying to communicate nuance to the general public. That's often a wise choice. :-)
PS. If you're at all interested in foraging mushrooms, buy a copy of All the Rain Promises and More, by David Aurora. (If you're elsewhere than North America, buy a local guide, too, but still get ARPM.) Aside from the mushroom content it's wonderfully entertaining.
I had a mushroom farm in Northern Michigan some years ago and we grew Golden Oysters, among other species. I think our winters are too cold for them to really establish themselves, but I was hearing reports of them 'going native' in Southern Michigan as long ago as 15 years.
Like the farmer in the article, I also wondered about the apparent lack of effort in growing native species. My area has a wonderful native oyster Pleurotus populinus; exceptional in taste compared to other oysters, but I have never heard of anyone cultivating them.
I've been thinking about farming in Michigan. If global warming takes off, we should have a nice environment and plenty of water to grow...
I just can't imagine doing agriculture in 2026. I have a masters in Mechanical Engineering and 2 decades of experience. It just seems like something for uneducated people.
Michigan already has a pretty great environment for agriculture. I used to always hear we were second only to California in terms of output. If current climate disruptions continue(we've had two "once in a lifetime" catastrophic ice storms just this past year in my area) I may searching for 'greener pastures' myself.
I would have thought all the fungus had long ago traveled around the world? Don’t they move easily on the wind or on items shipped from place to place.
Wikipedia: "The Last of Us is an action-adventure video game series and media franchise created by Naughty Dog and published by Sony Interactive Entertainment.[a] The series is set in a post-apocalyptic United States ravaged by cannibalistic humans infected by a mutated fungus in the genus Cordyceps."
I often read about invasive species from a Western point of view and some of the most aggressive and hard to keep under control species come from Asia. Is the Asian ecosystem equally invaded by Western species? Are forests and gardens in Asia overrun by European carp and grey oyster mushrooms? Or is there something about the environment and ecosystem in Asia that makes those species uniquely invasive and resistant?
For example the Japanese knotweed evolved to grow on the side of volcanoes and survive the occasional lava flow. It's a uniquely harsh environment which prepares it for thriving in any "gentle" garden in the world. But the mushrooms didn't evolve in any particularly bad environment, so why are these species outcompeting local ones? Why are they so fit for a new environment?
I know I have some selection and survivorship bias because I only know of the species that made it, not the ones which try to invade and fail so that's why I'm curious if this is a special situation of more or less expected, a known percentage of species from any part of the world end up outcompeting local species from another.
Wonder if I'll be able to add a new entry to the list of "mushrooms that supposedly grow in my region but cannot be located within 100 sq miles of my home" soon.
The iNaturalist.org map tab could help you determine whether it has been found in your area. [0]
I was hoping it had not made it to Texas since it was reported mostly in the NE US but it looks like some people have started cultivating it here and it may have escaped cultivation sometime during the last few years.
Considering that it is an invasive fungus that is known to degrade all the natives in the area it should be no surprise that the questions about whether the fungus was found growing on a grow block are rarely or never answered in the Texas reports. This could be due to the questions being asked by researchers trying to identify spread mechanisms from posts that are several years old. The original poster may not respond either because they don't remember or they are not as active as they used to be.
I think there are 8 reports in the state today and at least one is obviously in a grow medium of sawdust. [1] The fact that people placed most of their sitings on parks instead of home gardens when more than one case clearly shows a residential setting may suggest that they are growing something that they know can escape but they would like others to think they found it in the wild so it isn't their problem.
I have a great natural environment for them with several live oak widowmakers standing dead for around 25 years. I have not seen any yellow mushrooms though, yet. I think the native mulch industry in Texas will probably be their main spread vector since hardwoods are mulched locally and sold all over the state. As far as I know there are fewer restrictions on mulch sales from infected areas than there are on firewood sales across county lines. I think mulch may incorrectly be classified as compost in this case where the assumption is that there has been large scale degradation sterilization of weed seeds, fungal spores, etc due to decomposition temperatures.
I’ve proposed that someone open a restaurant of invasive species. You could make some decent dishes with lionfish, blackberries, golden oyster mushrooms, venison, etc
The Himalayan Blackberry produces untold numbers of very large fruits and it's still so aggressive you have to ruthlessly clear it before it grows under your foundations and into your driveway and walls. It takes over every patch of ground it gets access to and it will send runners down 20 or 30 foot concrete walls from the top of the freeway. I once saw it grow a runner up to the top of a 40-foot tree and then back down to the ground 10 feet away. The thorns are so thick it will penetrate everything but duck cotton. I have to wear welding gloves when I'm clearing it because it can go right through gardening gloves. It is a hell plant sent to torment us for our hubris.
If you've ever bought or eaten "marionberry" this plant is where it grows.
Kudzu's threat has been long overstated. It thrives especially near forest edgelands which are always visible on highways, so concern of prevalence was partially based on individual sampling error. In reality, its presence in southern forests is higher than desired but still not disastrous (~0.1% of southern forestland), which is a fraction of worse invasives: Japanese honeysuckle (4.4%) and Asian privet (1.4%).
> ~0.1% of southern forestland), which is a fraction of worse invasives: Japanese honeysuckle (4.4%) and Asian privet (1.4%).
Sample size of 1 here (I know), but I've spent a meaningful portion of my life outdoors in the south and I have _never_ seen swaths of the landscape covered with Japanese Honeysuckle or Asian Privet like I have Kudzu. It absolutely dominates _everything_ in areas where it's present here (not surprising when it can grow up to a 1 foot (0.3 m) a day.)
Not trying to say you're incorrect, just trying to get a better handle on this. The thought that there are more destructive invasive plants in the US south than Kudzu is kind of blowing my mind.
I would say that it's more accurate to say that kudzu is not poisonous. I definitely would not say it tastes good. It's got that "green plant" taste that you get from just chomping on any ol' leaf you might find. I mean, if you're poor and starving you could maaaaaybe survive on Kudzu, but it will be rough, it's not very calorie dense, even for a leafy green. Goats won't even eat it unless there is literally nothing else to eat. This whole, "oh you, can eat kudzu!" thing is just crunchy-mom Instagram influencer bullshit.
I tried to read TFA to learn about what's going on. It's an article about an invasive species of mushroom, right? I'd like to be informed.
The first sentence is:
"The razor blade of the newly unpacked surgical scalpel glints in the late Autumn light."
So I just immediately stopped reading.
This style of writing is exhausting and too common. It's an article about mushrooms, not a spy action thriller.
It feels like there had been some shift over the past decade that has been pushing / encouraging this style of writing, and I'm not sure what's caused it or what the solution is.
It's getting to the point that I'll need to use an LLM to summarize any article I care about to just extract the relevant info.
That would be particularly ironic if it was an LLM that generated the article.
The vast majority of writers at the end of the day write these stories to sell them. The old venues that sold advertising to places where you would read the stories you are talking about are long dead. Google, et al, have sucked up all that money making them a trillion dollars. Now anyone that wants to sell a story is left fighting for pennies on clickbait.

I don't have any addictions in my life, but one. That's when morel season is in swing, I am in full hunt mode.
A friend of mine went to a local mushroom picking course and among things they mentioned that morels are difficult to cook from fresh, because of the gastro problems. Apparently, the advice was to dry them before using in recipes.
What's up with that?
Superstition/caution.

I've never heard of this. In fact, I'd go so far to say myself and those that taught me try our best to not let them dry out. Can you explain further?

The good news is that's edible and apparently tastes good.

Unstoppable until you acquire a bunch of goats.
But what if your goats become unstoppable?
You start an unstoppable business cleaning up dams and freeways of brush.
Then you have found the goat
Apply wolves!
If they became unstoppable, we'll need unstoppable humans! Wait~~
We must continue this chain until we reach unstoppable sapient topological "aberrations" in space-time with reversed arrows of time.
Christopher Nolan, is that you?
But what if the wolves become unstoppable?
We turn them into dogs.

You might want to tell the japanese and vietnamese that it doesn't taste good then, they seem to have been using it as food for quite a while now
The root, not the leaves.
Well it's lucky I didn't say anything about the leaves then
Wonder if this will have the Wolf phenomena: Where wolf populations explode until there is no food left.
For the most part, these mushrooms eat dead trees, so
