The Mushroom at the End of the World follows one of the strangest commodity chains of our times to explore unexpected corners of capitalism. Here, we witness the varied and peculiar worlds of matsutake commerce: the worlds of Japanese gourmets, capitalist traders, Hmong jungle fighters, Finnish nature guides, and more. These companions also lead us into fungal ecologies and forest histories to better understand the promise of cohabitation in a time of massive human destruction. The Mushroom at the End of the World is an original examination of the relationship between capitalist destruction and collaborative survival within multispecies landscapes, the prerequisite for continuing life on earth.
