>>864937It's almost certainly in the genus amanita.
I'd hazard a guess that it could be Amanita phalloides, based on the the greenish tint to the cap.
For your information, most amanitas are poisonous to a degree-- and a few will kill you. Like 'skip the doctor, call the priest' kill you. Only the very experienced should pick amanitas to eat.
Where did you pick this? What sort of environment did you pick it in?
