Does anyone know of publicly traded companies that are actively working in the fungi domain, especially ones where more than 50% of their revenue comes from fungi growth, cultivation, or fungi-based products (especially mushrooms)?
I have been searching but did not find anything worthy of investing with peace of mind, only very low revenue companies or ones that are fully private.
Reason: Guard against food shortages, as growing mushrooms seems like a really stable and not problematic economic endeavor.
