What Type of Mushroom is this?
I am no mycologist, but I think it looks like the false death cap, Amanita citrina var. alba.

I'm basing this mostly on color, size, and the universal veil remnants on the cap.  Here is a picture for comparison:




  Amanita citrina is now known to contain the toxin alpha-amanitin;
  however, if eaten in normal amounts it is considered the concentration
  is so low that it is unlikely to have any significant effect on a
  healthy adult. Of far greater risk is the possibility of confusion
  with one of the deadly Amanita species such as the Deathcap, Amanita
  phalloides, or the Destroying Angel, Amanita virosa. For this reason
  our advice is not to eat Amanita citrina, whether it is raw or cooked
