1912 E. A. Minchin Introd. Study Protozoa viii. 128 In many cases, union of distinct individuals can be observed which have nothing to do with syngamy, since no fusion takes place of nuclei, but only of cytoplasm. Such unions are distinguished as plastogamy (or plasmogamy) from true syngamy.

1958 L. A. Borradaile et al. Invertebrata (ed. 3) ii. 40 Here may be mentioned the union of individuals by fusion of their cytoplasm, the nuclei remaining distinct, which is practised by the Mycetozoa..and in some other cases. This process, which is not syngamy, is known as plasmogamy, and its product as a plasmodium.

1969 F. E. Round Introd. Lower Plants iv. 60 In most of the higher terrestrial fungi, plasmogamy, which is the fusion of small masses of cytoplasm containing the nuclei, is separated in time from karyogamy.

1986 M. Kogut tr. H. G. Schlegel Gen. Microbiol. v. 155 Sexual reproduction can usually be divided into three phases. The first is plasmogamy, the fusion of two protoplasts.
