This is an Amanita with a dark brown to blackish brown pileus that is sometimes paler toward the striate margin. It suggests A. fulva of more northern countries in its habit and in its whitish, saccate volva that often becomes stained rusty and is adpressed to the stipe in its lower portion. The stipe is exannulate. Pileus color, lamellar trama, subhymenial configuration, and spore size differentiate the Neotropical taxon from A. fulva. The Amanita pictured here was originally described from Colombian oak forests (Mem. New York Bot. Garden 66: 10-12. 1992.)
