For over fifty years, the Puget Sound Mycological Society (PSMS) has nurtured collaboration amongst its members for an understanding and appreciation of the wide diversity of mushroom species in the Pacific Northwest. We also depend on a diverse membership to support our mission to foster the understanding and appreciation of mycology as a hobby and a science. In recent months, as systematic inequality in U.S. society is revealed to a broader audience, it becomes clearer that inequality imposes barriers on marginalized groups to participation in a wide variety of activities. PSMS opposes all barriers that limit participation in mycology. PSMS and its board members support a more diverse, inclusive, and welcoming organization where all people, especially those who are underrepresented in our organization and society at large, can enjoy mushrooms and all of the activities associated with them. We realize this will be an on-going conversation and are looking to our members for suggestions on ways to increase diversity, inclusivity, and welcoming. Thank you as we join together to make this long-overdue journey toward systemic equality!

Virtual Monthly Meeting

Tradd Cotter - Mushroom Mountain: Opportunities with Fungi that Make a Difference

Click here to join this meeting anytime after 7pm on Tuesday to say hello and 'mingle'.

Mushrooms are fascinating. Problem Solvers. Opportunistic. Orchestrating complex and dynamic physical and chemical behaviors that can make a difference in our present and future. Tradd Cotter discusses how he started Mushroom Mountain and how the business has evolved to stay on the fringe of ideas that can help solve hunger, disease, and beyond. Inspiring to mycologists, gardeners, students and environmentalists, this lecture showcases a promising and optimistic movement towards planetary healing using fungi, encouraging viewers to join a community of creative and goal oriented citizens who want to change the world. The future of civilization depends on every one of us making a difference. It doesn't take a million years to evolve. It will happen overnight.

Tradd Cotter is a microbiologist, professional mycologist, and organic gardener, who has been tissue culturing, collecting native fungi in the Southeast, and cultivating both commercially and experimentally for more than twenty-two years. In 1996 he founded Mushroom Mountain, which he owns and operates with Olga Katic, to explore applications for mushrooms in various industries and currently maintains over 300 species of fungi for food production, mycoremediation of environmental pollutants, and natural alternatives to chemical pesticides. In 2014, Tradd completed and published the best-selling book Organic Mushroom Farming and Mycoremediation (2014), that is still one of the top ten releases with the publisher, Chelsea Green. Tradd has won numerous awards for his work including the prestigious Clemson University Entrepreneur of the Year Award (2013), the EPA GRO-U Fellowship Award (2011), and an expert lecturer on all topics related to fungi in agriculture and medicine. His primary interest is in low-tech and no-tech cultivation strategies so that anyone can grow mushrooms on just about anything, anywhere in the world. Mushroom Mountain is currently expanding to 42,000 square feet of laboratory and research space near Greenville, South Carolina, to accommodate research for commercial production of new and experimental species, as well as mycoremediation projects. In 2018 Mushroom Mountain started a daughter company, MYCOMATRIX, that develops novel medicinal extracts for consumers and cobranding into consumer products. In 2019 Mushroom Mountain opened THE BLUE PORTAL, a psilocybin research and mediated session center, that is available in Jamaica and soon Costa Rica. Tradd's current research projects include bacterial interactions with fungi and novel antibiotic discovery.
