Green-spored Parasol Chlorophyllum molybdites

Is mine the same as yours? http://www.projectnoah.org/spottings/7147568

Looks to me like a dry young specimen (I say "dry" because of how the gills are a mess near the edge of the cap and I say "young" because of the yellow gills that eventually turn gray or greenish.) It's growing on the ground near grass, has the brown-patches-on-white-cap thing going on, is sporting the uplifted and depressed cap shape, the brownish-reddish stalk is complete with a persistent ring, and the gills are free (not at all touching the stem). Cosmopolitan and poisonous -- not a good combo!
