Walla Walla, WA — a donation-based mushroom culture library + spawn laboratory: mushroom species, liquid cultures, grow kits, substrate, agar media, free education (videos, Q&A, workshops). Ethos = OPEN-SOURCE MYCOLOGY ("genetics are of the commons, accessible to anyone willing to maintain them"); DIY, sustainability, fungi-as-allies, rejecting purely profit-driven biological conservation.
