Amanita grandis is a sequestrate (secotioid) (underground) mushroom from Australia. It was described in 2017 as part of the highly supported Southern temperate clade of the Amanita genus, which includes other Australian species like A. inculta and A. pseudoinculta . ^[1]

As a member of the Amanita genus, A. grandis is similar having a white spore print, light-colored gills, and a volva, which is a sac or cup at the base of the stem. However, as an underground or secotioid species, its appearance differs significantly from typical above-ground mushrooms like the Fly Agaric (A. muscaria) or the deadly Destroying Angel (A. phalloides). ^{[2] [3]}
