I will grant you that those are some nasty-looking mushrooms.
But that’s not fair to common button mushrooms, which to me are the very soul of innocence ... especially sautéed in real butter.
My Dad always liked to recount how he and grandpa used to go mushroom hunting in Buffalo’s Chestnut Ridge Park. My old Polish grandpa had a perfect eye for which ones you could eat and which ones to stay away from.
Personally, I’d just as soon get mine from the produce section at Publix.
