The Victorian coroner has issued a warning over the dangers of consuming wild mushrooms following the death of an elderly woman in Melbourne's east earlier this year.

Judge John Cain found 98-year-old Loreta Maria Del Rossi died on May 22 a week after eating a meal made from mushrooms foraged from her own garden.

The coroner found the Bayswater woman died from multi-organ failure due to poisoning from amatoxins, which are found in death cap and yellow-staining mushrooms.

The coroner's findings into Mrs Del Rossi's death were released today.

Mrs Del Rossi lived with her adult son and grew her own vegetables and also regularly collected wild edible grasses such as dandelion and milk thistle.

The coronial inquest said she had found mushrooms growing in her yard on May 15, 2024, which she thought were edible as she had previously eaten mushrooms collected from the same patch of ground.

However, she and her son fell ill after consuming the mushrooms. She died in hospital a week later while her son survived.

Judge Cain noted the Victorian Department of Health produced a variety of resources about the dangers of foraging wild mushrooms and how to identify poisonous ones, however he found more could be done to educate people.

"I commend the Department of Health for publishing a health advisory regarding the consumption of wild mushrooms," he said. 

He recommended the Department of Health and the Poisons Information Centre design and run an advertising campaign to run each autumn about the dangers of consuming wild mushrooms.

Wild mushrooms typically grow in Victoria as the weather becomes wetter and cooler.

The yellow-staining mushroom is the most commonly eaten poisonous mushroom as it resembles mushrooms that can be bought in supermarkets.

The death cap mushroom is usually whitish, yellow, pale brown or green in colour and often grows under oak trees.
