Autumn conditions have created ideal growing conditions for poisonous mushrooms, Victoria’s Chief Health Officer Professor Charles Guest has warned.
“People should avoid gathering wild mushrooms in rural Victoria and from their own gardens because of the risk of collecting poisonous varieties which may appear very similar to edible varieties,” Prof Guest said.
He identified the dangers of two of the state’s most dangerous varieties, the Death Cap fungus, Amanita phalloides and the Yellow Staining mushroom, Agaricus xanthodermus.
The warning coincides with the arrival of the mushrooming season, spawned when rain encourages growth of the fungi in the still warm earth.
“While commercially-sold mushrooms are safe, poisonings can occur when people gathering wild mushrooms inadvertently include toxic species,” Prof Guest said.
“Anyone who becomes ill after eating mushrooms should seek urgent medical advice and, if possible, take samples of the whole mushroom for identification.
“The most dangerous variety is the Death Cap, usually found near deciduous trees, especially around oaks, in some Melbourne suburbs and rural areas.
“The Death Cap is extremely toxic and responsible for 90 per cent of all mushroom poisoning deaths.
“Death can follow within 48 hours.”
The Death Cap is a large mushroom, with a cap ranging from light olive green to greenish yellow in colour.
The gills are white, and the base of the stem is surrounded by a cup-shaped sac.
Prof Guest said the commonly found Yellow Staining mushroom turns yellow when the cap or stem is bruised by a thumbnail.
“These are often gathered and mixed with field mushrooms, and can cause nausea, abdominal pain and diarrhoea in some people,” he said.
“If you have any doubts about a species of fungus or mushroom, don’t eat it.”
