All of these photos were taken of mushrooms that came up following about 6" of rain over a 4 day period (result of a nor'easter). They came up along an approximately 20X150' strip of pine trees next to a walkway next to Plumeri Park (College of William and Mary). I would assume that they are all the same species... but there seemed to be a lot of variety in form.

Any id's would be appreciated. A friend of mine suggested they are a an Amanitas fungi, which after a bit of online research seems right, but I'm not sure which variety?
