Jessie Uehling is a mycologist and an Assistant Professor of Fungal Biology in the Department of Botany and Plant Pathology at Oregon State University. She runs a mycological research lab focused on genetic diversity and evolution of fungi via their symbioses with other organisms. She currently is also a co-chair and the Mycologist for the Oregon Psilocybin Advisory Board. In this talk she will describe the morphological and genetic diversity of psilocybin producing fungi. She will also detail the current usage by species and country, and ethnobotanical history for psilocybin producing fungi uses. Last she will describe the structure and functioning of the Oregon Psilocybin Advisory Board, and mycological logic underpinning recommendations for what are now the ORS 475A Psilocybin Regulations.
