It was reported that she thoroughly washed, cleaned, and tested the white mushrooms.

However, this time Del Rossi and her son both fell severely ill and were rushed to hospital.

Del Rossi’s condition worsened and she died a week later. Her son survived.

Coroner Judge John Cain released his findings on Wednesday, saying the mother and son had consumed a death cap mushroom which is often pale yellow, green or whitish in colour.

He confirmed she died from organ failure following amanita poisoning, the toxin found in both death cap and yellow-staining mushrooms.

The amatoxins found in these mushrooms are lethal in small doses, where a 50g mushroom can deliver a fatal dose to a 70kg adult.

Despite the Victoria health department publishing an advisory on wild mushroom consumption, the coroner said there needs to be improved public messaging to avoid further tragic deaths.

“I commend the Department of Health for publishing a health advisory regarding the consumption of wild mushrooms,” he said in a statement.

“However, I believe that additional public awareness is merited.”

The death came nearly a year after three people died following a fatal beef wellington lunch.

Erin Patterson is accused of murdering her former father-in-law Don Patterson, his wife Gail, and Gail’s sister Heather Wilkinson after they ate poisonous mushrooms in the meal at her home on July 29 last year.

All three died in hospital days afterwards. Heather’s husband Ian Wilkinson miraculously survived after he spent two months in hospital.

Erin Patterson pleaded not guilty to three counts of murder and five counts of attempted murder.

Three of her attempted murder charges are related to her estranged husband following “three separate incidents” where he fell ill between 2021 and 2022.
