Notes Non-membranous occluding material is associated with older septal pores. Septal pore cap detailed structure from Tu et al., 1977. For three-dimensional reconstruction of septal pore apparatus using freeze-substituted material, see Mueller et al., 2000; filaments anchor the septal pore cap; ZIO stains endoplasmic reticulum associated with septal pore cap ;1,6-_-glucan localized to septal pore swelling.
