The woman charged with the three so-called mushroom murders has been remanded to reappear in the Victorian Supreme Court on August 21.

Erin Trudi Patterson, 49 of Leongatha, appeared before Judicial Registrar Tim Freeman on Thursday to determine the next steps in the court process.

The court is expected to sit for a week, then again on October 7 after Ms Patterson’s decision to have the evidence tested for the first time in the Supreme Court.

Ms Patterson, who has pleaded not guilty, is being held in a maximum-security wing of the Dame Phyllis Frost Centre in Melbourne’s west.

She allegedly served a beef Wellington meal last July 29 that police said killed her former in-laws, Don and Gail Patterson, both 70, and Gail Patterson’s sister, Heather Wilkinson, 66.

The meal was allegedly served at Ms Patterson’s house in Leongatha, about 140km northwest of Melbourne, with Ms Patterson saying she also fell ill from the same meal that police said included death cap mushrooms.

She is also charged with attempting several times to murder her former husband, Simon Patterson, 49, and Wilkinson’s husband Ian, 68.
