模式标本的比较。gerdemannii和A. Applyula显示孢子在组织和亚细胞结构上相同，表明它们是同种的。A.在原始文献中没有给apapulula命名，但有11个活的培养物起源于或产生A. gerdemannii也产生类似球囊霉属的孢子，其形态与细枝球囊霉的模式标本中的孢子相同。这些孢子与G. fecundisporum，表明它们是同种的。这两个物种在同一篇论文中被描述，因此命名为G。Leptotichum被优先考虑，因为模式标本处于更好的状态，并且来自参考培养物的标本已被两个序言的作者鉴定。从培养的寄主植物的单孢子和多孢子接种物中确认了二型性和缺乏有性型，这为确定A. gerdemannii和G. leptotichum是一种泡囊丛枝菌根真菌的无性型。
Comparison of type specimens of A. gerdemannii and A. appendicula revealed the spores to be identical in organization and subcellular structure, indicating they are conspecific. The Glomus morph of A. appendicula was not assigned a name in the protologue, but 11 living cultures started from or producing spores of A. gerdemannii also generated Glomus -like spores of identical morphology to those in type specimens of Glomus leptotichum . These spores were indistinguishable from those in type specimens of G. fecundisporum , indicating they are conspecific. Both species were described in the same paper, so the name G. leptotichum is given priority because type specimens are in better condition and specimens from a reference culture have been identified by an author of both prologues. Absence of a teleomorph and confirmation of dimorphism from single and multiple-spore inoculations of host plants in culture provide the basis for designating A. gerdemannii and G. leptotichum as synanamorphs of one vesicular-arbuscular mycorrhizal fungus.
