Amanita grandis is a sequestrate (secotioid) (underground) mushroom from Western Australia.
Amanita grandis has a white spore, light-colored gills, and a volva, but as a secotoid, it looks different than other above-ground mushrooms.
Amanita grandis is found in Western Australia.
Grandis means "great" or "large," so Amanita grandis means "great mushroom."
