The enormous popular interest in the world of fungi and the mycelium testifies to its tremendous resonance as a metaphor for new ways of thinking, new systems and behaviors. Taking its inspiration from this world, Let’s Become Fungal! looks at a range of Indigenous practices from Latin America, the Caribbean and Asia that are rooted in multispecies collaboration, symbiosis, alliances, non-monetary resource exchange, decentralization, bottom-up methods and mutual dependency―all suggestive of the behavior of the mycelium. Each of the book’s 12 chapters offers teachings on collaboration, decoloniality, nonlinearity, toxicity, mobilization, biomimicry, death and being nonbinary, while also examining the world of fungi. Let’s Become Fungal! shows how fungi can inspire artists, collectives, organizations, educators, policymakers, designers, scientists, anthropologists, curators, urbanists, activists, gardeners, community leaders, farmers and others to become more fungal in their ways of working and being.
