title: Heterocaryotic Nature of Ring Formation in the Predaceous Fungus Dactylella doedycoides.
abstract: Morphologically indistinguishable conidia of the predaceous nematodeattacking hyphomycete Dactylella doedycoides Drechsler vary in their ability to produce constricting rings, depending upon their heterocaryotic state. Three types are noted: those producing rings with or without stimulation, those never producing rings, and a mixed or wild type, made up of a mixture of the first two types.
