About 10 years ago after retirement my wife and I sitting on our front porch drinking iced tea and she brings out a large salad for us. It was fantastic and had everything...except mushrooms.
We had lots of rain and I saw some in the yard so I got my mushroom book and one the book had pictured said very delicious with almond flavor, so I picked it. It was delicious so I cut it up putting in salad. I tried coaxing wife to try it but she refused.
All was well for about half an hour then I felt weird. Dizzy and disoriented, finally about to collapse. Wife said go outside and force vomit which I did. I had just enough presence of mind to put that same type mushroom in a zip lock bag as she called 911.
We live close to a rescue squad, ambulance was there in minutes. I took sample and a 5 gallon bucket with me because I couldn't stop vomiting.
At the hospital I gave them sample to analyze before I passed out. A nurse came by for me to sign a Do Not Resuscitate form. There was a restroom nearby and wife helped me there, continuous regurgitation.
I asked about the mushroom sample and they said the almond flavor was cyanide and it contained "every poison known to man and then some". Apparently it wasn't my time to go and I credit my wife having me vomit.
Back home I looked at the mushroom book again. In small print it said do NOT confuse this mushroom with the deadly ******!
To this day my wife won't eat a mushroom and used to love them because it reminds her of the day she almost lost her husband.
