Psilocybe allenii was described as new to science in 2012 by Jan Borovička, Alan Rockefeller, and Peter G. Werner. Borovička received material collected from Seattle, Washington, which he noted was microscopically similar to Psilocybe cyanescens, but lacked the wavy cap margins characteristic of that species.
