Intracellular Hyphae hyphae which grow within root cells. Lateral Roots roots which grow from another root. They increase the roots contact area with the soil. Spores sometimes called azygospores, blastospores or chlamydospores. They form as swellings on one or more subtending hyphae in the soil or in roots.
Spores usually develop thick walls, which often have more than one layer.
The spores are believed to be the long-term survival propagules of the fungus. This can be misleading, as the sporocarps produced by most glomalean fungi are small and relatively unorganised compared with the sporocarps of ectomycorrhizal fungi. These may be inter- or intracellular. Vesicles accumulate lipids and may develop a thick wall. They function as infective propagules for some species of AMF and develop into spores in some species of Glomus .
