- The saccate volva is attached only near the base of the stem, grayish on the outer surface, and 20-35 mm wide.
- Volvariella is the third genus in which one encounters an obvious volva in the gilled fungi.
- Amanita fulva is tawny and has a volva that is not constricted and often stains rusty brown.
