利用电子显微镜对蜜环菌隔膜发生及其结构分化进行研究。隔膜的形成首先是菌丝内壁横生，至中心时停止发育留下中心孔，孔侧的隔膜板膨大形成桶孔隔膜；同时孔口两侧出现孔帽，它是由内质网修饰而成；内质网、高尔基体、线粒体均与隔膜的发育有关。菌索髓部的薄壁菌丝处于休眠状态，这类菌丝和液体发酵时菌丝的隔膜均缺乏孔帽，但后者有较大的隔膜孔口，胞质环流明显，菌丝间融合频率高。此外，本文较系统阐述了蜜环菌隔膜结构变化与其功能的相关性。
The occurrence and structure differentiation of Armillaria membranaceus septa were studied by electron microscope. The formation of the diaphragm is the first lateral wall hyphae to stop the development of the center to leave the center hole, the hole side of the diaphragm expansion to form a barrel diaphragm; at the same time holes on both sides of the hole cap, which is modified from the endoplasmic reticulum; Endoplasmic reticulum, Golgi, mitochondria are related to the development of the diaphragm. The mycelial parenchyma hyphae hyphae in dormant state, these mycelium and liquid fermentation mycelial septa are lacking hole cap, but the latter has a larger diaphragm orifice, cytoplasmic circulation significantly, the fusion between mycelium High frequency. In addition, this article systematically elaborated the relationship between the structure change of Armillaria mellea septum and its function.
