Fungi are entering human bodies, consciousness, and culture at unprecedented scales and instigating significant changes in our systems. Pathogenic fungi with pandemic potential like Candida auris and Aspergillus fumigatus are infecting us at increasing rates. Fungal compounds like psilocybin and related tryptamines have always affected human neurobiology, cognition, and spirituality, and are going mainstream.

Instead of seeing fungi as the infiltrating "other," this article introduces the possibility of seeing these developments as an emerging collaboration— a symbiotic partnership with an increasingly strengthening mycobiota impacting human physiology and spirituality, forming the foundation of the mycological posthuman.

Building on Anna Tsing's contamination as collaboration framework, as well as Donna Haraway's natureculture synthesis, this article speculates on a fungal-instigated speciation event for humanity.

I argue that this coevolutionary perspective allows for a radical and feral imagining of human futurism— one that embraces nonhuman kin, absolves us of the isolation and spiritual deprivation of human exceptionalism, and embodies a new vision of wild kindness.
