PSMS Inclusivity Statement

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!

Noah was the recipient of the 2022 North American Mycological Association's Award for Contributions to Amateur Mycology. His primary research interest is on the taxonomy and systematics of fungi. He authored, along with Christian Schwarz, Mushrooms of the Redwood Coast, a Comprehensive Guide to the Fungi of Coastal Northern California and Mushrooms of Cascaida, a Comprehensive Guide to Fungi of the Pacific Northwest, as well as A Field Guide to the Rare Fungi of California's National Forests.
