摘要从母孢子萌发到休眠的过程中，描述了蜜色无梗内生孢子的精细结构。出现了三个不寻常的细胞器，即。色素颗粒、大晶体和自我复制的细菌样有机体。前两种孢子数量很多，与孢子形成有关。色素颗粒参与蜂蜜色壁的沉积，当细胞质从母体进入休眠的孢子时，色素颗粒变成髓鞘样图形。这些晶体的功能尚不清楚，但在休眠孢子进入休眠之前最为明显。类细菌有机体可能是共生在真菌中的放线菌孢子，随着孢子进入休眠，它们会大量繁殖。休眠的孢子含有很少的细胞质，压缩成一个非常大的多边形油球和被认为含有储存多糖的大圆体之间的精细网络。
SummaryThe fine structure of honey-coloured, sessile Endogone spores is described from initiation of the mother spore to dormancy of the resting spore. Three unusual organelles occur viz. pigment granules, large crystals and selfduplicating bacteria-like organisms. The first two are very numerous, and are specifically associated with spore formation. The pigment granules are involved in the deposition of the honey-coloured wall, and change into myelin-like figures when cytoplasm moves from the mother into the resting spore. The crystals, whose function is not known, are most conspicuous just before the resting spore reaches dormancy. The bacteria-like organisms, which may be actinomycete spores living symbiotically in the fungus, multiphy greatly as the spore enters dormancy. The dormant spore contains very little cytoplasm compressed into a fine network between very large polygonal oil globules and large round bodies thought to contain a storage polysaccharide.
