Stalked puffballs do have a stalk that supports the gleba. None of the stalked puffballs are edible as they are tough and woody mushrooms. The Hymenogastrales and "Enteridium lycoperdon", a slime mold, are the "false puffballs". A gleba which is powdery on maturity is a feature of true puffballs, stalked puffballs and earthstars. False puffballs are hard like rock or brittle. All false puffballs are inedible, as they are tough and bitter to taste. The genus "Scleroderma", which has a young purple gleba, should also be avoided.
