Puffball
While most puffballs are not poisonous, some often look similar to young agarics, and especially the deadly Amanitas, such as the death cap or destroying angel mushrooms. It is for this reason that all puffballs gathered in mushroom hunting are cut in half lengthwise. Young puffballs in the edible stage, before maturation of the gleba, have undifferentiated white flesh within; whereas the gills of immature Amanita mushrooms can be seen if they are closely examined.

Puffball [SEP] Edibility and identification
It has been estimated that a large specimen of this fungus when mature will produce around 7 × 10¹² spores. If collected before spores have formed, while the flesh is still white, it may be cooked as slices fried in butter, with a strong earthy, mushroom flavor. Not all true puffball mushrooms are without stalks. Some may also be stalked like the "Podaxis pistillaris" which is also called the "false shaggy mane". There are also a number of false puffballs that look similar to the true ones.
