Death Cap or False Death Cap?

I did a little digging to see the base of this one.
It was late, the light was bad (used the flash) but I think its either a death cap or a false death cap.
It could just as well be a champignon, but the gills looked white, not brown.

If it is a death cap, you can only eat it once.
