ABSTRACT: Neohaploidization of dikaryon cultures of Pleurotus was performed usint oxgall agar techniques. Neohaplont isolates were monokaryotic and lacked clamp connections. These neohaplont isolates were mated with single- spore tester strains of formerly identified Pleurotus collections, and neohaplonts from each parent dikaryon were found to be compatible with tester strains of only one species. Such a process appears valuable as a means of identifying dikaryon Pleurotus cultures, and may be as useful for other fungal groups.
