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. Seasonal sporulation has been observed in arbuscular fungi Gemma et al.

Glomus chimonobambusae and Entrophospora kentinensisspp. Intraradical hyphae developed parallel to each other and to the root axis, rarely had Y-shaped branches, sometimes had short lateral branches or knobby swellings, and were 2. Globose, subglobose, occasionally irregular.

The fungi associated with Gentiana lutea L. Then proceed back to the spore wall. Extraradical hyphae infrequently occurred and were 2. Literature data and the results of long-term investigations of the author of this website suggest scrobiiculata Ac.

Arbuscules were not numerous and usually were unevenly distributed along the roots. Germination wall 2 contains two layers gw2l1 and 2.

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. Layer 2 plastic, 0. At maturity, the pore is closed due to deposition of a material coming from the cytoplasm of the spore.

Arbuscules in cortical cells of corn root. Click on the language titles to launch them. Using Google Analytics, we can see what content is popular on our websites.

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.

In most mature spores, sporiferous saccule is detached. Germination wall 1 consists of two, flexible, hyaline layers gw1l1 and 2tightly adherent to each other in moderately crushed spores, but usually separating in vigorously crushed spores; each layer ca. The photo above was provided acaulosopra of Joyce Spain from her publication. Three acwulospora vesicular-arbuscular mycorrhizal fungi Endogonaceae from Poland.

Mode of formation of this region is analagous to that which occurs during synthesis of spore wall layers in Glomus species.
