In mycology, a volva is a cup-like structure at the base of a mushroom that is a remnant of the universal veil,[1] or the remains of the peridium that encloses the immature fruit bodies of gasteroid fungi.[2] This macrofeature is important in wild mushroom identification because it is an easily observed, taxonomically significant feature that frequently signifies a member of Amanitaceae. This has particular importance due to the disproportionately high number of deadly poisonous species contained within that family.
The volva is the prominent cup-shaped feature at the base of this Amanita caesarea.

A mushroom's volva is often partially or completely buried in the ground, and therefore care must be taken to check for its presence when identifying mushrooms.[3] Cutting or pulling mushrooms and attempting to identify them later without having noted this feature could be a fatal error.
