Appearance

A skirt-like annulus is found on its stipe, and the base of the stipe is bulbous and encased in a saccate volva.

Toxicity

The cap, gills, stipe, and spores are all poisonous. The species contains amatoxins which are deadly to humans.

A. marmorata may have a strong odor that can develop from mild to pungent over time.

Spores

A. marmorata spores are spheroid to ellipsoid. They have a white to cream spore print.
