“E. hochstetteri is a mushroom, and it’s blue. It’s really, really, really blue—almost unbelievably blue, saturated in a way more often associated with kids’ markers or mouth-staining candy than with fungi. The diminutive mushrooms play an outsized role in New Zealand’s cultural landscape and also flourishes in locals’ lives, with the Māori using these mushrooms as food, medicine, and pigments for tattoos.”
