Found solitary in leaf litter, it had a deep olive to olivaceous-buff cap with white flesh where the skin had been peeled.

The tall stem was also olivaceous-buff, but bitten away to reveal white flesh. The gills were white and also bitten.

It had a white volva and no visible ring.

Most species of Amanita, including A. phalloides, have a ring, so I am uncertain of this identification.
