The connection between saccule neck and spore is somewhat complex in that it initially consists of only the L1 layer of the spore continuous with the wall of the saccule neckfollowed by synthesis of sublayers of the L2 laminate layer which form between saccule neck and spore.

Other differences between A. Glomus constrictus, Sclerocystis clavispora, and Acaulospora scrobiculata.

In other spores, iw1 may produce one to many folds, thus giving the appearance of a bewildering array of flexible inner walls and making diagnosis difficult. Layer 3 flexible, hyaline, 0.

However, it is considered to be part of the spore wall because it usually is integral adherent and sometimes shows evidence of just being another sublayer lamina of the spore wall. Specimens and strains links: Arbuscules often stain lightly in trypan blue, but sometimes stain more darkly; intensity of staining appears to vary with many factors that have yet to be resolved possibly age of the mycorrhizae and of acaulospoar host root.

It is analagous to L3 found in other species with ornamented spore walls, such as A. Layer 1 evanescent, hyaline, 1. This orb is difficult to see except in older spores where contents have cleared with fusion of lipid globules in the spore lumen, mostly because it is wide enough to span most of the diameter of the spore and so edges of the orb are seen only with a limited range afaulospora spore orientations.
