Amycel For more than 45 years, Amycel has helped shape the way commercial mushrooms are grown. From the proprietary strain genetics behind some of the most widely grown brown mushrooms in the world, to grower-to-grower field support that starts on the farm, mushroom operations around the globe rely on Amycel to perform. Premium spawn. Trusted supplements. A relentless focus on quality and consistency. That foundation has not changed since 1979. What has changed is scale. Today Amycel serves commercial growers across the Americas and Europe, with production and support on three continents. Our R&D program runs 32 dedicated test rooms focused on new genetics and inputs that help growers get more from every crop. Current priorities include:

• Strains developed for higher yield and reduced water use
• Kodiak, launching Summer 2026, requires up to 50% less water for the same yield
• Spawn carriers engineered to reduce green mold and compost waste
• Delayed-release supplement technology that protects compost and extends flush viability
