Which stands for Yet Another Small Brown Inocybe. Which is a group of poorly understood mushrooms. Even after John gets together enough descriptions they will still be something 20 species that look about the same, but have microscopic differences. (Just a prediction…)

John Brown would like to have these. He is studying the Inocybe of central CA and has about 70 species so far!
