Also a good book i would suggest is edible wild mushrooms of illinois and surrounding states. Depending on your location in indiana you might be able to find a member on here to go with and learn some different mushrooms.
There are several types of puffballs. And yes they are edible. The picture is of a jem studded puffball. Cant find my other puffball pics right now. But you can look up the identifications of the puffball group.
