Be very careful of the fall puffballs. When they are small, amanitas look the same as the puffballs and are quite deadly. I don't usually pick puffballs unless they are at least grapefruit size. Even then, slice them in half right through the root. If they are amanitas, they will show the stem and gill outlined in the middle.
Here is a quote from a website that says it well...
\"With smaller puffballs you must make sure the entire fruiting body is homogeneous, consistently the marshmallow texture. You should slice down the center of every puffball to make sure there is not a pre-formed mushroom inside. If so, it is likely to be an immature form of the death angels, Amanita bisporigera, Amanita virosa, and Amanita verna. They are all deadly. Do NOT eat them. In fact they are quite cruel. Feeling better after the first attack is the sign of impending death. Ninety percent of all mushroom fatalities involve amanitas.\"
Good advice BCastle.
And when they are this big (as shown below in the pic)is a sure indication they are giant puffballs and even a novice shroom hunter should feel safe if they are unsure. Amanita's do not get as big as a basketball. So if there is doubt for anyone out there on weather or not to try eating a puff ball and if anyone has any reservations just eat the ones that are soccer ball size or larger like this one below.
100% sure they aren't devil urns.. They could be very young Xylaria Polymorpha (Dead Man's Fingers) or the start of very young earthstar that black dot in the center has me thinkin earthstar.. They aren't ediable for sure.
