Abstract
SUMMARYBased upon data obtained from a study of the type as well as from Heim's and Singer and Smith's descriptions and from several fresh specimens collected by the author, Psilocybe aztecorum is here emended. This fungus is reported for the first time from four new localities in the states of Mexico and Tlaxcala. Psilocybe bonetii is reduced to varietal status of P. aztecorum. Relationships with P. baeocystis, P. quebecensis and P. cyanescens are discussed and a possible evolutionary pathway of these species is proposed. The description of P. baeocystis is emended.
