These four photos are most likely Amanita bisporigera, the Eastern Destroying Angel, at various stages of growth. The first one looked vaguely like a small puffball, as the gills were barely formed and the edges were hidden underground. As you can see, cutting it in half shows that it is a poisonous Amanita, not a puffball.
Perhaps some of these flat ones are Honey Mushrooms? I see that next time I will have to take samples home if I really want to find out what they are.

P.S. These pictures were taken in West Virginia in September.
