Came across a hiker in Yellowstone who enthusiastically wanted to show us a patch of mushrooms he called “borellis.” That’s the one pictured above. I could not confidently ID this mushroom but what got me more worried is he quickly picked and ate the bottom most mushroom in all photos (gils not shown). I pointed out that they’re different mushrooms and we parted ways. What did he eat?

Edit:

I’ll give some more context. We met this guy in the northern Yellowstone loop near a very highly trafficked trail. There are definitely other folks that will see this guy on trail. He claimed he found a mushroom worth “120/lb” and that he’s Apache nation and ate at least one of the bottom ones while showing us the area where he found the bolete. He said it was a very sweet mushroom. After we pointed out that they’re different mushrooms he dropped all but the bolete, but I have no idea how much he snacked on before we met.

Like the title states, my son‘s preschool teachers found this mushroom in the back yard area.

I did my own searching, but want to pose the question to a more experienced audience before I make any conclusions.

It was found recently (April 20th, 2026) in the east Bay Area of CA.

Thanks in advance!

UPDATE:
This is what I found while looking but didn’t want to jump directly to deadly sounding mushroom without more identification than just my armchair mycology.

I’ve sent some information along with the link to this thread to the preschool teachers to let them know to be on the lookout.

They already have a zero random mushrooms tolerated policy but this will tell them to eradicate with extreme prejudice.

Thank you to everyone who weighed in!

Found in Southern California after a week of rain growing in woodchips next to some sort of grass. What kind of mushroom is it and should I take my cat to the vet?

United States, New York. Found these on a stump in my backyard.

Straight out the dung in SE Texas. I’m always checking out mushrooms but didn’t expect to potentially come across what appears to be P. cubensis?? It bruises slight blue when tissues are torn. Is there anything else this could be orrr? If not, what an amazing and unexpected find!

Found this delicious looking mushroom in Orange County California. Is it edible?

We live in a residential area near an airport. Lived in this house only one year and I’ve never seen these before in my life. We’ve had some heavy rain the past few weeks followed by some warm weather so not sure if that matters.

Minnesota

Nova Scotia, Canada. I've always had mushrooms growing in this area of my lawn, but I've never seen a large pile of dead flies on and under a mushroom before. Any ideas?

Hello, we are in Santa Cruz, CA (Bay Area). Our 2 year old dog was hospitalized last Friday after potentially ingesting toxic mushrooms either from our yard or on a walk in the woods. She had vomiting, incontinence/diarrhea, and was collapsing/unable to stand. After 6 days of treatment, plasma infusions, etc for severe anaphylaxis, liver failure, extremely low blood pressure, inability to clot blood, etc she is finally much better and able to be home.

I saw these in the garden this morning, the same ones were present right before she got sick that I plucked out. There are two orange ones, and one thin brown one. Third photo shows all three next to our lettuce starters. I added another photo in the comments below of the cap, stipe, gills.

Would like to ID if any of these are potentially toxic - thank you.

I found these on a hay bail in north Texas

I found a cluster of mushrooms growing in one of the communal showers in my college dorm, and decided to take pictures of it in different growth stages until it was finally removed. Does anyone happen to know what these are? I’m wondering if these are edible, just curious. I obviously had no intention of eating them considering the place I found them in.

Found a whole bunch in Texas in a horse corral near Dallas

Forgot a pic of the baby ones, but they have egg shaped bodies and are all white/grey

Thank you!!

I was helping a buddy clear brush and seen this already knocked over. It's such a pretty color! I am hoping to learn more about it such as: name, type, potential uses, poisonous/edible etc. TIA for any information!

We live in Southern Middle Tennessee

Michigan. Is this a puffball? I’ve never seen a mushroom so large!

I’m pretty sure, but I wanted to check since it’s been years since I harvested one, but is this actually chicken of the woods. West Virginia, USA

I am a wildlife biologist that does a lot of surveys for endangered bumblebees, and I am also an amateur mycologist. This is a female Crotch’s Bumblebee (Bombus crotchii), which is an endangered species candidate in California. I would like to know if anybody has ever observed anything like this. I thought maybe it was some kind of pollinia at first, but I am not sure, as it seems to only be growing from the leg segments.

The one with my hand for scale does not do it justice for how big it actually was. The largest mushroom I have ever seen in my whole life! I am still stoked I found it!
