## Root Cause

Amanita phalloides (death cap) can have a white, yellow, or olive cap but always has a volva; it contains amatoxins causing delayed liver failure with no antidote; color alone is not a reliable identifier.

## Dead Ends

- **** — Amanita phalloides often has a white cap and peels easily; the peel test is not diagnostic. (75% fail)
- **** — Amatoxins are heat-stable and remain toxic after boiling, frying, or baking. (60% fail)
- **** — Death caps in North America often have white or pale yellow caps; green is only one variant. (70% fail)
