Amanita brunnescens, also known as the brown American star-footed Amanita^[1] or cleft-footed amanita is a native North American mushroom of the large genus Amanita. Originally presumed to be Amanita phalloides by renowned American mycologist Charles Horton Peck it was described and named by George F. Atkinson of Cornell University. He named it after the fact that it bruised brown.^[2]

It differs from the death cap by its fragile volva and tendency to bruise brown.
