The outer limiting layer of the spore coat of Nosema apis is relatively smooth. The inner limiting layer shows two fractured faces, the concave face carrying many stud-like projections, 120 nm long and 50 nm high, while the convex face carries numerous depressions which are complementary to the projections. In addition, the convex face bears 7 nm particles. In between the outer and inner limiting layers lies the thick homogeneous portion of spore coat which is comprised of numerous microfibres, each 9 nm in diameter. These microfibres resemble those in the freeze-etched host endocuticle. Next to the inner limiting layer of the spore coat are double spore membranes. The convex faces of these spore membranes have a dense population of particles, each 7 nm in diameter.
蜜蜂微孢子虫孢子壁的外限制层相对光滑。内限制层呈现出两个断裂面，凹面上有许多柱状突起，长120纳米，高50纳米，而凸面上有许多与突起互补的凹陷。此外，凸面上有7纳米的颗粒。在外限制层和内限制层之间是孢子壁的厚均质部分，它由许多微纤维组成，每根直径9纳米。这些微纤维类似于冷冻蚀刻的宿主内表皮中的微纤维。在孢子壁的内限制层旁边是双层孢子膜。这些孢子膜的凸面上有大量直径为7纳米的颗粒。
