Are contaminated/rotten/wild mushrooms safe for me to eat?
The simple answer is no.
The simple answer is no. But, you probably knew that before you clicked on this link.
Bad, rotten or unidentified shrooms should never be eaten under any circumstances. What you don't know might kill you.
NEVER give a friend a mushroom you wouldn't eat yourself.
Not all contaminated shrooms are deadly, some contaminants will not hurt you, but it is not worth taking the chance, nor is it worth learning which contaminants are worth eating. What you don't know, CAN hurt you. Avoid contaminated shrooms at all cost. Nobody needs to trip so badly that they should eat potential poison.
