摘　　要：为揭示网柄细胞状黏菌的超微结构特征,对簇生岐柄菌Cavenderiafasciculata生活史过程中的孢子、黏变形体和柄细胞3种类型的细胞超微结构进行系统观察,并与目前仅知的3种网柄细胞状黏菌的超微结构进行比较。结果表明:簇生岐柄菌C.fasciculata的孢子、黏变形体和柄细胞内均有线粒体结构,随着细胞分化,线粒体内部结构逐渐破坏,并被自噬泡吞噬;孢子表面具有线状纹饰。The ultrastructural characteristics of spore, myxamoeba and sorophore of Cavenderia fasciculata were observed, and comparison of ultrastructural characteristics was made between three known dictyostelids, Dictyostelium multiforme, D. minimum and C. fasciculata. The observation results showed that there were mitochondrial structures in spore, myxamoeba and sorophore of C. fasciculata. With cell differentiation, the inner structure of mitochondria is gradually destroyed and phagocytized by autophagic vesicles. The surface of spores has linear ornamentation.
