The 2025 Mushroom scholarship fund recipients
The Hort Innovation Mushroom Fund Scholarship Program, delivered by the AMGA, is opening doors for the development of knowledge in mushroom production. Backed by the industry’s R&D levy, this international education initiative gives Australian Agaricus mushroom growers and compost producers the chance to dive deeper into critical topics, learn from global expertise, and bring those insights home to strengthen the entire industry.
In 2025, the scholarships will provide six recipients with partial funding support to participate in the Mushroom Compost Masterclass. Facilitated by Mark den Ouden from the Mushroom Office, the masterclass is comprised of self-paced online learning modules followed by a five day intensive study tour in Europe.
Manipulating Agaricus bisporus developmental patterns by passaging microbial communities in complex substrates
The cultivation of Agaricus bisporus depends on a delicate balance of microbial interactions in the compost – which provides nutrients, and the casing layer – which supports fruiting.
While some bacteria are known to influence mushroom growth, researchers have had little opportunity to study how entire microbial communities shape developmental patterns.
This study explored whether deliberately altering these microbial communities could shift the way mushrooms develop, with the longer-term goal of improving yield management and sustainability.
Researching viral diseases
In 2020 Australian mushrooms with patch disease and brown cap were observed, however the virus complex detected differed to the complex associated with MVX.
A Hort Innovation levy funded project (MU22003) led by Agriculture Victoria and commenced in May 2024, aims to better understand the variation in viral signatures between MVX and the Australian patch and brown cap disease.
Growing beyond peat: the PEATLESS consortium
A new European consortium has launched the PEATLESS project, aimed at accelerating the transition to sustainable growing media with significantly reduced peat content. With the tagline #lesspeat, the initiative will develop, test and promote low-peat blends tailored for three key horticultural sectors: mushrooms, seedlings, and ornamentals.
Coordinated by the Technological Research Centre for Mushrooms of La Rioja (CTICH), the project brings together 12 partners from four countries — including research institutes, universities, industry players and policy makers.
Backed by €4.2 million from Horizon Europe and the Swiss State Secretariat for Education, Research and Innovation (SERI), the consortium will run from 2025– 2028.
Mushroom marketing update Spring 2025
The Australian mushroom industry is operating in a changing marketplace, with shoppers tightening household budgets. However, consumer research shows that mushrooms continue to be recognised for their taste, versatility, and health benefits. These strengths that can be amplified with the right investment.
Through the mushroom marketing levy, the industry has committed to a bold, multi-channel marketing program for 2025–26. The aim is simple: keep mushrooms top of mind for Australians and ensure consumers see mushrooms as a ‘must have’ on their weekly shopping list.
For growers, understanding this plan is vital. Not only does it demonstrate how levy funds are being invested, but it also highlights when and where promotional activity will peak, all valuable information for aligning supply, planning promotions, and anticipating consumer demand.
Mushrooms in China
Insights from Shanghai scientists
One of the key objectives of the Australian mushroom industry is to increase annual consumption from approximately 2.8kg to 4kg per person. Our current consumption is similar to that in the USA, Ireland and the UK, but higher than that in Europe, which is only 1.3kg per person annually.
However, these consumption rates are tiny compared to China. In 2023 China produced around 44 million tonnes of mushrooms. Given a population of 1.4 billion, some estimates put annual consumption at up to 29kg per person.
MLMRU update Spring 2025
A new project has commenced to help secure the future of the MLMRU over the next three years.
The project, Marsh Lawson: Elevating Mushroom Excellence Through Continual Research (MU24005) is a three-year levy-funded project that builds on the previous project and will continue to provide management and research services at the MLMRU.
This investment is designed to help the mushroom industry drive innovation, facilitate sustainable business practices, adopt best practice beyond compliance, adapt to climate change, and foster new expertise through dedicated R&D pathways.
What do do if you have orange cecids
Three species of mushroom cecid have been known to occur in Australia: The orange cecid Mycophila barnesi, the white cecid Heteropeza pygmea, and the yellow cecid Henria psalliotae (Nair and Clift 1993). In the last two decades, the reported incidence of cecids has been very occasional and in each instance only orange cecids have been observed. The major concern with a cecid outbreak is that it makes the mushrooms unsaleable.
Invaders versus emerges
Understanding their different roles in phorid infestation for effective management
Mushroom phorid flies (Megaselia halterata) are a significant pest of button mushroom cultivation systems. The terms invader and emerger were first applied by Michael Wolfin and his associates at Penn State University to describe two critical stages in the mushroom phorid fly life cycle. Understanding these different stages is important for effective integrated pest and disease management (IPDM) and can be used to guide phorid control strategies.
If something goes wrong
Protecting food safety in mushrooms
Food safety in mushroom cultivation relies on vigilance, preparation, and the ability to respond quickly when things don’t go to plan. While the Australian Agaricus industry has a strong record of producing safe, high-quality mushrooms, no system is completely risk-free.
Food safety incidents can still occur even when growers are following best practices. The decisions made in the first moments are critical. Acting promptly and correctly protects not only your customers and your business, but also the reputation of the wider mushroom industry. That’s why it’s essential for growers to understand the practical steps to take, the resources available, and the value of leaning on industry expertise and support networks.
Death cap mushroom murder
Defending the industry’s reputation in the face of scandal
It could have been the script for Midsomer Murders: a family lunch in a quiet country town, three tragic deaths, whispers of poison, and a swirl of intrigue that gripped the nation.
But this was no television drama. It was a real event, and one that, while completely unrelated to Australia’s commercial mushroom industry, created one of the most significant reputational risks the sector has ever faced.
What followed was a careful, measured communications response by the Australian Mushroom Growers Association (AMGA), with advice provided by expert PR Agency, Porter Novelli.
The response was guided by a single objective: to protect and uphold the reputation of the mushroom industry in the face of intense media scrutiny.
Final report summary: Alternate casing substrate – providing review of research to date and an expert forum for future R&D investment (MU22009)
We've pulled together a concise two-page summary of the Alternative casing substrate - review of research to date and expert forum for future R&D investment project to make key insights from the full Hort Innovation final report easier to access.
The summary highlights the objectives, methodology, key findings, and recommendations to help the Australian mushroom industry respond proactively to a deep dug casing phase-out, giving growers a clear pathway toward sustainable, locally sourced casing alternatives.
This summary also includes a link to the full final report.

Help improve the management of viral diseases of mushrooms.
Your input is vital to protecting Australia’s mushroom industry from costly viral diseases. Agriculture Victoria is inviting growers to take part in a national survey that will map the presence of viruses in Australian mushroom crops. By contributing samples, you’ll not only strengthen the industry’s ability to detect and manage diseases like La France and patch/brown cap, but you’ll also receive confidential insights into the health of your own crops - at no cost to you.
La France disease and Mushroom Virus X (MVX) complex are viral diseases that cause significant economic losses overseas, because of poor yields due to pinning disruption and discoloured and deformed mushrooms. La France disease is present in Australia.
MVX has not been reported in Australia, but patch and brown cap symptoms, like those associated with MVX, were recently observed. The virus profile of affected Australian mushrooms differs to that observed for MVX overseas, suggesting a different viral complex might cause the disease.
As a part of a Hort Innovation funded project to understand the viruses associated with in Agaricus mushrooms in Australia, Agriculture Victoria is conducting a survey determine which viruses are present in both healthy and diseased Australian mushrooms. The information will be used to develop surveillance tools that can be used by industry for early detection, accurate diagnosis of disease, and patch and brown cap disease prevention.
The success of this survey depends on your participation:
Participation will help to improve the outcomes of the project for industry.
The participating farms will receive information about the viruses that were detected and risks associated with their detection.
All grower information will remain confidential: only de-identified data will be presented in any communications.
The cost of virus testing is free for participating growers.
Participating in the study is simple:
1. Collect mushroom samples and pack them in paper bags.
a. Each sample should contain a minimum of five mushrooms.
b. If there is disease on farm, please include at least one sample from a healthy crop along with diseased samples.
c. Symptoms of virus infection include – browning, bare patches, distorted mushrooms, premature veil opening, and poor shelf life.
2. Number the samples sequentially.
3. Complete the survey form.
4. Send the samples to:
AgriBio – Crop Health Services, SAMPLE RECEPTION - MAIN LOADING DOCK, 5 Ring Rd, La Trobe University Campus, Bundoora, Victoria, 3083.
Submission of samples for this survey closes on 30 September 2025. For further information or enquires please contact Madhav on madhav.chandarana@agriculture.vic.gov.au
