As the crisp air of autumn settles over Victoria and gardens come alive with new growth, there’s a hidden danger sprouting beneath our feet: poisonous wild mushrooms.
Health authorities are sounding the alarm, urging all Victorians—especially those with curious grandchildren or pets—to be extra vigilant as two of the most dangerous fungi, the death cap and yellow-staining mushrooms, make their annual appearance.
Why the sudden warning?
With the arrival of wetter and colder weather, conditions are perfect for wild mushrooms to flourish in parks, gardens, and even suburban backyards.
While many mushrooms are harmless, a handful can be deadly—and unfortunately, they’re often mistaken for edible varieties.
Victorian Chief Health Officer Dr Christian McGrath has issued a stern warning: ‘Adults and children should not touch wild mushrooms with their bare hands, let alone eat them, and animals should be kept well away from them.’
The message is clear: unless you’re a trained expert, foraging for wild mushrooms is a risk not worth taking.
The usual suspects: death cap and yellow-staining mushrooms
The death cap mushroom (Amanita phalloides) is responsible for the vast majority of mushroom-related deaths worldwide. Just one bite can be fatal, and tragically, it closely resembles some edible varieties.
The yellow-staining mushroom (Agaricus xanthodermus), while not usually fatal, can cause severe gastrointestinal distress and is easily confused with common field mushrooms.
Both types can pop up in unexpected places, including your own backyard, local parks, and even in mulch around garden beds.
What makes these mushrooms so dangerous?
The toxins in death cap mushrooms attack the liver and kidneys, often with devastating consequences. Symptoms of poisoning can take hours to appear, by which time the damage may already be done.
Early signs include stomach pain, nausea, vomiting, and diarrhoea—symptoms that can easily be mistaken for a simple stomach bug.
Yellow-staining mushrooms, on the other hand, contain phenol-based toxins that can cause severe stomach upset. While not usually life-threatening, they can still lead to a very unpleasant experience.
Protecting your family and pets
Dr McGrath recommends a cautious approach: ‘Anyone who collects and consumes wild mushrooms of unknown species is putting themselves at risk of potential poisoning and serious illness. Consuming a death cap mushroom can be fatal.’
If you spot wild mushrooms in your garden or local area, here’s what you should do:
Don’t touch them with your bare hands. Always wear gloves.
Remove them carefully. Place the mushrooms in a bag and dispose of them in a closed general waste bin (not green waste or compost).
Keep children and pets away. Curious little hands and noses are especially at risk.
Never eat wild mushrooms unless you are an expert. Even experienced foragers can make mistakes.
What to do if you suspect mushroom poisoning
If you or someone you know has eaten a wild mushroom and is experiencing symptoms such as stomach pain, nausea, vomiting, or diarrhoea, seek medical attention immediately. Time is critical—early treatment can save lives.

Why Are Mushrooms So Hard to Identify?
Many poisonous mushrooms look almost identical to edible varieties. Even seasoned foragers can be fooled, and there are no simple ‘rules of thumb’ to distinguish safe from dangerous mushrooms.
Colour, shape, and size can all vary, and some toxic mushrooms even grow alongside edible ones.
A growing problem in Australia
Australia’s changing climate and gardening habits mean that poisonous mushrooms are appearing in more places than ever before.
Imported mulch, garden beds, and even potted plants can harbour dangerous fungi. In recent years, several cases of mushroom poisoning have made headlines, with tragic outcomes.
While it might be tempting to pick wild mushrooms for a home-cooked meal, the risks far outweigh the rewards. When in doubt, leave them out—and remind friends and family to do the same.

I am now 70years old and have picked mushrooms around our farm in Qld since I was about 5 years old, with my Mum originally. I have never had a bad mushroom, but I may also have left a lot of good mushrooms behind I wasn’t sure. The pictures you have shown don’t say that all or some are death cap! I think you are stirring up a good story without accurate pictures as the media seems to do lately. How about more accuracy in your stories.
