Erin Patterson concedes death cap mushrooms were in beef Wellington she fed guests

That’s it for our coverage of today’s court hearing. Read Erin Pearson’s wrap of what happened today below. We’ll continue our live coverage of the trial on Wednesday.


Accused killer cook Erin Patterson has conceded death cap mushrooms were in a beef Wellington she fed her lunch guests after telling a jury she often foraged for fungi and enjoyed buying exotic varieties because they tasted better.

Patterson, 50, spoke for the first time about the meal that killed three people and made another critically ill during a second day of evidence in her murder trial in Supreme Court at Morwell.

“Do you accept there must have been death cap mushrooms in it?” defence barrister Colin Mandy, SC, asked his client.

“Yes I do,” Erin Patterson replied while nodding.

When asked where the mushrooms for the meal came from, she said the “vast majority” came from her local Woolworths supermarket in Leongatha and others from an unknown Asian grocery store in Melbourne.

Erin Patterson said the mushrooms she bought from the Asian grocer in April 2023 smelled really pungent, so she put them in a container back at her home in Leongatha.

She added that she remembered also putting wild mushrooms she had dehydrated around May or June 2023 in a container that already contained other dried mushrooms.

Erin Patterson has pleaded not guilty to the murder of her in-laws, Don and Gail Patterson, Gail’s sister Heather Wilkinson, and the attempted murder of Ian Wilkinson, in July 2023. She claims their deaths from mushroom poisoning were a terrible accident.

The mother of two told the jury she had developed an interest in mushrooms and foraging during COVID lockdowns in 2020 and listed the Korumburra Botanic Gardens, a nearby rail trail and her own backyard as places where she remembered picking them.

Erin Patterson said she first noticed mushrooms growing at her former Korumburra home when her dog ate some. She said she was worried they could be toxic and researched them.

“The dog was eating some and I picked the mushrooms that I could see because I wanted to try and figure out what they were to see if it was a problem,” she said.

“As far as I could see they were ones that were potentially edible but there was one species I was a little bit worried about. I believe they were called inocybe. There’s Facebook groups for mushroom lovers, Facebook groups for everything, where people share what they find. I scrolled a lot of them.”

She told the jury that eventually she had sliced a piece of mushroom she had found growing at her home, cooking it in a pan with butter.

“They tasted good and I didn’t get sick. Sometimes [I would] put them in meals we all ate,” she said.

The accused told the court she later grew confident enough to try the ones she found on her own properties – in Korumburra and later Leongatha – identifying some in a paddock of her three-acre Gippsland property as field and horse mushrooms.

Erin Patterson said as she continued to forage for wild mushrooms thereafter, she would chop them up and cook them in meals she and her children ate.

The accused said bought a dehydrator in April 2023 to preserve both wild and store-bought mushrooms as well as other food.

“So fun fact the dehydrator reduces mushroom mass by 90%. Do you think Woolies would mind if I brought the dehydrator into their vegetable section,” she wrote in a post to friends on social media.

In one photograph she sent to her friends, she showed off the dehydrator with mushrooms drying on the shelves, telling the jury she went on to hide mushrooms in everything.

It was around May and June 2023 that she was picking wild fungi, including field, slippery jacks and honey mushrooms, from her property.

The accused said to identify them she went through a research process before eating them and was “very confident” she knew what they were.

She said she also spotted other types of fungi on her property, but she could not figure out what type of mushroom they were so did not pick them.

Erin Patterson said she really loved mushrooms and had shared this interest with her Facebook friendship group.

“I tried a lot,” she said.

“I used them in curries or pasta dishes or soups, spaghetti. They [the more exotic mushrooms] just taste more interesting, more flavour – more exotic mushrooms.”

Sipping from a paper cup as she spoke, she said the women had become like her “cheer squad” and she would talk about religion, life, children and the things they cooked, alongside news events.

Erin Patterson explained that was one reason why she “vented” to them about her problems with estranged husband Simon and his parents, messaging that she wanted “nothing to do with them”

She said at the time she felt hurt, frustrated and a little desperate, and her online friends made her feel heard, validated and understood.

“I knew that the women would probably support me being annoyed about those things,” the accused woman said.

“I wish I’d never said it. I feel ashamed for saying it and I wished the family did not have to hear that I said that. They did not deserve it.

“I needed to vent, I needed to get my frustration off my chest. And the choice was either going to the paddock and telling the sheep or vent to these women. But I regret the language that I used.”

Erin Patterson was also admitted to lying about her health, agreeing with her defence barrister that she had never been diagnosed with cancer – despite telling her lunch guests she had been – or had a needle biopsy on any lumps on her elbow.

She told the jury she had become concerned she might have ovarian or brain cancer, becoming “Dr Google” to self-diagnose her symptoms after previous experiences with hospitals left her distrusting the medical community.

Erin Patterson also gave the jury an insight into her turbulent marriage, saying that after a number of break-ups and reconciliations she and Simon had formally separated in 2015.

“In the immediate aftermath, weeks, it was difficult as it had been at other separations but that only lasted a handful of weeks, we went back to just being really good friends,” the accused said.

“I did not want to be separated but I felt there was no choice. Our primary problem was if we had a disagreement or any kind of conflict, we didn’t seem to be able to talk about it in a way where either of us felt heard or understood, we’d just feel hurt and didn’t really know how to do that well.

“We really liked each other still, it was just the living together that did not work.”

She said her relationship with her in-laws, Don and Gail Patterson, didn’t appear to change and she felt they “continued to love me”, describing how she became unfairly frustrated when they wouldn’t intervene in problems she was having with their son.

Asked why she kept the couple’s houses in both their names, Erin Patterson revealed she had always wanted the family to come back together one day.

“That’s what I wanted. I did that because I wanted some way to demonstrate to Simon that’s what I really believed and wanted. [That] I see a future for us,” she said.

The trial continues.

What happened on day 25 of the mushroom trial

By Mike Bruce

That’s a wrap for today’s live coverage. Here’s a brief summary of what took place in court today:

  • Erin Patterson detailed to the court where she would forage for mushrooms in her local area.
  • Patterson told the court that she foraged for mushrooms after developing an interest in fungi from about 2020, during the COVID pandemic lockdowns.
  • Patterson spoke about her lifelong battle with body image and see-sawing between restricting food and binge eating. Leading up to July 2023, she would binge on food an average of two or three times a week.
  • Patterson spoke of her regret at sending a message to a Facebook friend group about the family of estranged husband, Simon Patterson, including one that said, “This family I swear to f---ing God”.
  • Patterson said she had never been diagnosed with ovarian cancer or had a biopsy on her elbow, but confirmed she had raised concerns with doctors she might have cancer after experiencing some symptoms.
  • A tearful Patterson described her separation from husband Simon and her enduring bond with her in-laws, saying they formally separated at the end of 2015, but no lawyers were involved, nor was there any acrimony.
  • Patterson said she inherited money from her grandmother’s estate after her death in 2006. Among other things, it allowed her to offer loans of about $400,000 each to siblings of estranged husband Simon.

Erin Patterson’s children knew of her mushroom foraging habits

By Marta Pascual Juanola

Erin Patterson’s children definitely knew that she was picking mushrooms and might have spotted some for her on some occasions.

She said she had a habit of taking the mushrooms home, cleaning them, slicing them and putting them in a Tupperware container in her pantry if she wasn’t going to use them that day.

Patterson told the court that the mushrooms she bought from an Asian grocer in Melbourne in April 2023 smelled very pungent, so she put them in a container and took them back to her home in Leongatha.

Patterson told the court she remembered putting wild mushrooms that she had dehydrated in about May or June 2023 in a container that already contained other dried mushrooms.

Where Erin Patterson foraged for mushrooms

By Marta Pascual Juanola

Erin Patterson has told the jury that she got a dehydrator to be able to preserve mushrooms for longer, including mushrooms she bought from Woolworths.

“I liked eating wild mushrooms, but it’s a very small season. You can’t keep them too long in the fridge, so it was one way of sort of preserving them for later in the year,” she said.

Patterson said she would forage for mushrooms in the Korumburra Botanic Park, her Shellcot Road property in Korumburra, the rail trail leading out of Leongatha and her block in Gibson Street in Leongatha.

The jury has been shown a message from Patterson to her online friends sent after she purchased the dehydrator where she told them: “So fun fact, dehydrator reduces mushroom mass by 90%”.

They have also been shown a series of images of the dehydrator and mushrooms on a scale.

“I’m pretty sure I picked them from the Korumburra botanic gardens,” Patterson said.

Patterson said it was a failed experiment to see if she could dehydrate them whole, instead of slicing them, but they were mushy in the middle. She said that she was weighing the mushrooms at the time to see if she had removed all the water before dehydrating them.

“I mainly picked field mushrooms ... but there were a couple of other interesting ones,” she said. Those included slippery jacks and honey mushrooms, she said.

Patterson said she had tried those, and they tasted “very nice”.

Patterson said she had also found field mushrooms at her property in Gibson Street in Leongatha. She said she also spotted other types of fungi on the property, but could not figure out what types of mushrooms they were so did not pick those.

Patterson accepts meal contained death cap mushrooms

By Marta Pascual Juanola

After a break, defence barrister Colin Mandy, SC, is resuming his questioning of Erin Patterson by asking about the meal she cooked for lunch on July 29, 2023.

Patterson said she accepted the meal contained death cap mushrooms.

Asked by Mandy about where the mushrooms for the meal came from, Patterson said: “The vast majority came from the local Woolworths in Leongatha, and there was some from the grocer in Melbourne”.

Patterson said she purchased the mushrooms from Melbourne during the April school holidays in 2023. She said she had previously purchased shiitake, porcini, and maybe enoki mushrooms from that style of shop before.

“Sometimes the bag might say wild mushroom mix or forest mushroom mix,” she said.

From garden fork to kitchen fork: How Erin Patterson’s fascination with mushrooms grew

By Marta Pascual Juanola

Erin Patterson is continuing to tell the jury about her interest in mushrooms, which started with a love of their flavour and widened when she noticed wild mushrooms on the limited walks Victorians were allowed during COVID lockdown periods.

Patterson said mushrooms also grew at her former property in Korumburra, where she moved in 2017 or 2018. She said she first noticed the mushrooms when her dog was eating them and picked them up to identify them and check if they were poisonous.

“As far as I could see, there were ones that were potentially edible, but there was one species that I was a bit worried about,” she said.

“There’s Facebook groups for mushroom lovers ... where people share what they found and talk about the identify. I scrolled a lot of them.”

Patterson said she was eventually confident the mushrooms growing in the paddocks of her three-acre property were field and horse mushrooms, so she cut a piece of one mushroom, fried it with butter and ate it.

“They tasted good and I didn’t get sick,” she said.

Patterson said that from then on, whenever she would see the same mushrooms growing in the paddocks, she would pick them and eat them.

“Sometimes [I would] put them in meals we all ate,” she said.

Patterson said she chopped mushrooms small so her children wouldn’t pick them.

How COVID lockdown walks sparked Erin Patterson’s interest in wild mushrooms

By Marta Pascual Juanola

Erin Patterson has now started talking about mushrooms: how she loved to eat them, cook with them, too.

Patterson told the jury she would use them in curries or pasta dishes, soups and spaghetti. There was something about exotic mushrooms that tasted “more interesting”, she told the jury, and they had more flavour.

Patterson is being questioned about her past use of mushrooms in cooking by her defence barrister, Colin Mandy, SC.

The jury is shown messages sent by Patterson to online friends about her “hiding mushrooms in everything” and images she sent the friends of a dehydrator with mushrooms on the trays.

Patterson told the court she had an interest in wild mushrooms since early 2020. “The first COVID lockdown, when you are allowed [outside] for an hour a day, I would force the children to go out and get away from their devices for an hour,” she said.

The family would go to the Korumburra Gardens or the Rail Trail, and that was where she first spotted wild mushrooms. “It would have been the end of March, early April,” she said.

She said she had always enjoyed eating mushrooms. “They taste good and are very healthy,” she said. “I’d buy all the different types that Woolies would sell.”

Patterson said she would also get different types of mushrooms from farmers’ markets and grocers in Melbourne, including Asian stores she would visit while staying in the city with the children during school holidays.
