Stamets had invited me up to his place in Washington State, on the Little Skookum Inlet at the base of the Olympic Peninsula. I asked him, gingerly, if I could come at a time when the Psilocybes were fruiting. “Most of them have already come and gone,” he said. “But if you come right after Thanksgiving, and the weather’s right, I can take you to the only place in the world where Psilocybe azurescens has been consistently found, at the mouth of the Columbia River.”
