What is the issue?
Death Cap mushrooms
- Death Cap mushrooms (Amanita phalloides) are highly poisonous. Consuming just one mushroom can kill an adult. Symptoms of poisoning by Death Cap mushrooms can include violent stomach pains, nausea, vomiting and diarrhoea. Symptoms may subside after one or two days but this does not indicate recovery. Serious liver damage may well have occurred that may result in death.
- These mushrooms grow under oak trees and are 40-160mm in diameter. The cap ranges in colour from pale yellow green to olive brown and the ridges on the underside of the cap are white. The base of the stem has a membrane 'cup'.
- The Yellow-staining Mushroom (Agaricus xanthodermus) is the cause of most poisonings due to ingestion of wild fungi in Victoria. Consuming Yellow-staining mushrooms causes nausea, stomach cramps, diarrhoea and vomiting. The severity of symptoms varies with the amount eaten.
- This mushroom looks very similar to the Cultivated Mushroom (Agaricus bisporus) and to edible wild mushrooms such as the Field Mushroom (Agaricus campestris). In urban areas the Yellow-staining Mushroom is unfortunately much more common than edible mushrooms. It can grow in large troops in lawns and gardens.
Who is at risk?
