Presented are observations of 17 species in the following 14 genera. B lastocladiales : Allomyces and Blastocladiella . C hytridiales : Asterophlyctis, Catenochytridium, Chytridium, Chytriomyces, Cladochytrium, Entophlyctis, Phlyctochytrium, Rhizophlyctis, Rozella, Septochytrium , and two undescribed cladochytriaceous genera. Encystment without flagellar retraction is briefly considered. Recognized and described are four basic developmental patterns or methods of flagellar retraction: lash‐around, body‐twist, straight‐in , and vesicular . Variations in and combinations of the four basic methods are described. Observations, most of which are illustrated with brightfield, darkfield, phase‐contrast, and electron microscopy, along with what is known from the literature, are discussed and serve as the basis for generalized, summary diagrams or two‐dimensional models of patterns of flagellar retraction in posteriorly uniflagellate fungi. An endeavor is made to put the findings reported on in this paper in historical, morphogenetic, and phylogenetic perspective.
