>>2607068They are not deadly but will cause gastrointestinal upset if you don't prepare them. You can properly cook them by boiling them and discarding the water twice. Apparently they are above average in taste. But save the water since it is not psychoactive.
>>2608669I am a dirty hippy and have foraged, prepared, and tripped on Amanita muscaria (v. guessowii) a handful of times. If one has ever tripped on psilocybin mushrooms, one has absolutely no frame of reference for a Fly Agaric trip. The hypnotic effects while awake are strange enough but the dreams you get after you fall asleep are comparable only to DMT or salvia in their intensity. I can go into more detail if there's curiosity here.
>>2612149There are a few different yellow spotted Amanitas that look like this but not all of them are psychoactive, maybe you got unlucky.
