Glomus pansihalos Berch & Koske, Mycologia 78:832-836. 1986.

 Description: Sporocarps unknown. Spores borne singly or in loose clusters in the soil and sometimes in the root, globose, (60-) 90-120 (-180) μm diam, occassionally subglobose, obovoid, ellipsoid, 70-130 × 80-140 μm. Spores hyaline to pale yellow, becoming reddish brown or dark brown with age. Spore wall distinguished by two layers. Wall 1, hyaline to pale yellow, ornamented by cerebriform folds and spins, laminated, 2.5-5.0 μm thick; wall 2, brown to reddish brown, covered by spins, laminated, easily separated from wall 1, 2.5-6.0 μm thick, stained reddish brown in Melzer’s reagent, when young. Spores with one or two attachment hyphae. Attachment hypha 6-13 μm diam, tubular or funnel-shaped, sometimes constricted at the attachment, then tapering broader. Hyaline outer wall extending down to attachment hypha up to 100 μm. Attachment occluded by wall thickening.

Taiwan: Hualien. From the rhizosphere of Miscanthus sp., Wu-830819 (TARI). From the rhizosphere of the same host, Wu-831012 (TARI).

 Habitat: Hypogeous. Spores were isolated together with Acaulospora scrobiculata from the river bank of Moo-Gua-Chi in the rhizosphere of Miscanthus sp. In the rhizosphere of Cunnighamia lanceolata stands, Nan-Tou county.

 Note: Glomus pansihalos is distinguished from other species of Glomus by its magnificent ornaments on the spore wall. However, the hyaline outer wall and its ornaments disappered in 0.01% acid fuchsin-lactic acid staining solution
