The structure and development of septum in Armillaria mellea were studied under the electronmicroscope. Hyphal septum was developed by inside wall of hyphae in cross direction, leaving a small pore in the center. Then the septal plate arround the pore became swollen, and formed a septal pore apparatus called dolipore septum. With subsequent development of endoplasmic reticulum septal pore caps appeared on each side of the pore. Organelles, such as mitochondrium and Golgi body in hyphal cells were all related with the development of septa. Thin-walled narrow hyphae of the medualla in mature rhizomorph were in a state of dormancy, and their septa were similar to those of the hyphae growing from liquid fermentation. Both of them were short of septal pore caps, but the latter had larger septal pores, the protoplasm flow from cell to cell through the pore was visible, and fusion rate between the hyphae was much higher. The relationship between the structural changes and functions of septa in A. mellea was also systematically discussed in this paper.
利用电子显微镜对蜜环菌菌中隔的结构和发育进行了研究。菌丝中隔由菌丝内壁横向发育而成，在中央留下一个小孔。然后，围绕小孔的中隔壁肿胀，形成一种称为桶孔隔膜的中隔孔装置。随着内质网的进一步发育，在小孔的每一侧出现了中隔孔帽。菌丝细胞中的细胞器，如线粒体和高尔基体，都与中隔的发育有关。成熟菌索髓部的薄壁窄菌丝处于休眠状态，其隔膜与液体发酵产生的菌丝隔膜相似。它们都缺乏中隔孔帽，但后者的中隔孔较大，可以看到原生质通过小孔在细胞间流动，菌丝间的融合率也高得多。本文还系统地讨论了蜜环菌中隔结构变化与功能之间的关系。
