来自佛罗里达州的两种新的泡状丛枝菌根真菌(Endogonaceae)--双孢球菌(Glomus Ambiporum)和异孢球菌(G.Heterosporum)--在产生两种不同的孢子类型方面与以前描述的所有物种不同。双孢球菌的黑色孢子果或孢子果聚合体在土壤中产生，在寄主组织内形成透明孢子。结实孢子的外壁为近透明，有一层淡淡的六角板状网状结构。异孢球菌在寄主组织外部产生浅至深褐色的孢子果或孢子果皮聚集体，在寄主组织内形成透明的孢子。结实孢子的外壁透明、光滑、无光泽。两种植物的孢子果皮都有围绕中央菌丝丛径向排列的孢子，该菌丝丛类似于菌核菌的孢子果。这是球囊菌属的首次报道。
Two new vesicular-arbuscular (VA) mycorrhizal fungi (Endogonaceae) from Florida, Glomus ambisporum and G. heterosporum, differ from all previously described species in the production of two distinct spore types. Black sporocarps or sporocarp aggregates of Glomus ambisporum are produced in the soil and hyaline spores are formed within host tissues. The outer wall of sporocarpic spores is subhyaline with a faint reticulum of hexagonal plates. Glomus heterosporum has light to dark brown sporocarps or sporocarp aggregates produced externally to host tissues and forms hyaline spores within host tissues. The outer wall of the sporocarpic spores is hyaline, smooth, and evanescent. Sporocarps of both species have spores radially arranged around a central hyphal plexus which resemble sporocarps of Sclerocystis rubiformis. This is the first report of dimorphism in the genus Glomus.
