Re: What Whopper
Not sure, but I believe mushrooms have brown 'gills' under the top, white gills are usually (but not always) poisonous.
I vaguely remember something about a 'skirt' round the stem too.
Unless you're postiive beyond any doubt, Azure, it isn't worth risking it to me.
P.S.
Just did a goodle, and found this for you.
