FINE STRUCTURE OF A SPECIES OF AMOEBO-FLAGELLATE PSEUDOSPORA CIENK

Mixed cultures of the amoebo-flagellate and the alga on which it feeds were examined by electron microscopy. Both amoeboid and flagellate stags were sectioned and their morphology described, particular attention being paid to the flagellar bases and to the intra-nuclear fibrils. The latter are discussed with relation to nuclear fibrils in other organisms. The amoeba is compared with other amoebae whose fine structure has been examined, and the possible phylogeny of Pseudospora is considered. © 1969 Springer-Verlag.
