Muscarine and Muscarine Isomers in Selected Inocybe Species

Abstract
The distribution and relative concentrations of muscarine and its isomers in Inocybe species were determined. Notable was the finding that I. cinnamomea A. H. Smith, I. geophylla Karst, and I. lacera (Fr.) Quél. contained concentrations of epi‐muscarine equal to or‐higher than muscarine itself.
