Darker or Dark Spots

A mushroom is starting to go bad once there are already dark spots. Once you see developing dark spots or becoming darker then you should immediately use them or put them in the trash instead.


In some cases, mushrooms might not be slimy but could dry out and have some wrinkles. Avoid a mushroom that is too wrinkly. So once mushrooms are shrivelled up looking then avoid consuming them at all.

Emit Odor

Indeed, a fresh mushroom doesn’t have a strong or noticeable odor. But once there is, then they have gone bad already. Once you pick up the bag then open it and you smell something unpleasant, the mushrooms have already gone bad.
