用电子显微镜观察了黄顶孢霉的粘液变形虫及其转化为双鞭菌群细胞过程中鞭毛的发育阶段。用戊二醛锇固定。鞭毛形成过程与其他系统中报道的相似，包括基体出芽形成初级鞭毛囊泡，然后形成鞭毛鞘。两个基体存在于粘液变形虫前flagellum发展，其他形态特征的粘液变形虫和群细胞，包括系统的微管，进行了描述。两个阶段的线粒体都含有一个致密的核心，鞭毛呈现典型的“9加2”排列，轴丝的双线原纤维在鞭毛的圆形远端附近变成单线。
Myxamoebae of P. flavicomum and the stages of their development of flagella during transformation into biflagellate swarm cells were examined with the electron microscope. Fixation was with glutaraldehyde osmium. The flagellation process was similar to that reported in other systems, involving budding of the basal body into a primary flagellar vesicle which then forms the flagella sheath. Two basal bodies are present in the myxamoeba prior to f lagellum development; other morphological features of myxamoebae and swarm cells, including systems of microtubules, are described. Mitochondria of both stages contain a dense core, flagella exhibit the typical "9 plus 2" arrangement, and the doublet fibrils of the axoneme become singlets near the rounded distal end of the flagellum.
