Traffic stop may have prevented fatal death cap poisoning
A 22-year-old Perth man was pulled over in Manjimup with foraged mushrooms and drugs after police said he mistook death caps for psychoactive fungi.
A routine traffic stop in Manjimup may have kept a bad foraging decision from turning deadly. Western Australia Police said a 22-year-old Perth man was stopped on June 11 with mushrooms in his car that he had picked in the Margaret River region, and officers later told him the fungi could have killed him.
Police said the man appears to have confused death cap mushrooms with the psychoactive mushrooms he was hoping to find. Alongside the mushrooms, officers allegedly found methamphetamine and MDMA in the vehicle. The car was impounded for 28 days, and the man is due in Bunbury Magistrates Court next month on drugs charges.
The case is a sharp reality check for anyone who treats wild mushrooms like a treasure hunt. Lookalike assumptions are exactly how fatal mistakes happen, and once death caps are in the mix, a “successful” forage means nothing if the identification is wrong. The man was reportedly thankful for the intervention, but gratitude after the fact is a thin shield against a mushroom that can do its worst before symptoms even begin.
WA Health says the marbled death cap mushroom, Amanita marmorata, is extremely toxic and has been found in Western Australia’s South West region. The department says it was first identified in the Denmark area in 2016, and its full distribution in the state is still not known, which is why the safest advice is simple: do not eat any wild mushrooms.

Food Safety Information Council officials have been even blunter. They say the poison in a quarter of a cap of one death cap mushroom can be enough to kill a healthy adult, and symptoms usually do not appear for 10 to 16 hours after eating it. That delay is part of what makes these mushrooms so dangerous: by the time someone feels sick, the toxin may already have done serious damage.
The warning is not theoretical. Australian death cap poisonings have included deaths in Canberra in 2012, serious poisonings in the ACT in 2014, and a young child hospitalized in the ACT in April 2022 after eating a death cap mushroom. As foragers post more finds online and confidence spreads faster than field skills, the margin for error keeps getting thinner.
