Death from mushroom poisoning in Australia is rare and usually due to liver failure produced by Amanita phalloides. We report a 53-year-old woman in Queensland who died from an acute muscarinic syndrome 10 hours after eating mushrooms belonging to the genus Rubinoboletus. To our knowledge, this is the first death in Australia caused by non-amatoxin-producing mushrooms. It highlights the need for awareness of non-amatoxin-producing mushrooms as potentially lethal.
