Looks like a destroying angel (e.g. Amanita virosa) to me. This and the death cap together account for the vast majority of mushroom poisonings in the world. Cooking it will not destroy the toxins, nor will acid. Symptoms tend to appear 5-24 hours after eating, too late to pump the stomach. Half a mushroom can be enough to kill you.
I don't recommend going out to pick mushrooms unless you know what you're doing. If you do, stay away from the white ones. You can still get terrible stomach cramps and diarrhea from other colors of mushrooms, but the white ones have the most dangerous species.
Amanita bisporigera, or the aptly named eastern North American destroying angel, if anyone's wondering.
From Wikipedia:
The principal amatoxin, α-amanitin, is readily absorbed across the intestine, and 60% of the absorbed toxin is excreted into bile and undergoes enterohepatic circulation; the kidneys clear the remaining 40%. The toxin inhibits the enzyme RNA polymerase II, thereby interfering with DNA transcription, which suppresses RNA production and protein synthesis. This causes cellular necrosis, especially in cells which are initially exposed and have rapid rates of protein synthesis. This process results in severe acute liver dysfunction and, ultimately, liver failure.
I could not confirm that it causes liquefactive necrosis of the liver specifically, however. I wouldn't doubt it, but I couldn't confirm it.
Edit: I should clarify, I got this from the original thread on Bluesky, not my own identification.
i didnt even consider that this AI shit was going to claim to be able to ID mushrooms
ok ive been a little skeptical of the idea so far but now im fully convinced. this dumb ai shit is going to get people killed. like straight up more than one person is going to die because of these upjumped autocorrects masquerading as intelligence. and no one is going to be held responsible.
I remember being on a wilderness weekend many years ago and being told that when you cut the stem on some poisonous shrooms they discolour a sort of blue tint. I'm lucky, I hate the taste and texture of mushrooms.
