使用光学显微镜比较了地下三叶草根内 10 种内根菌科 (Endogonaceae) 形成的囊泡-丛枝菌根的解剖结构。在单一真菌种类的盆栽培养中，每种真菌在地下三叶草的根部形成了一种特征性的感染模式。来自球囊霉属（G. tenuis 除外）、无梗孢霉属和大孢霉属的真菌很容易相互区分。在每个属内，物种形成具有不同形态的菌丝或囊泡的程度各不相同。属之间的差异总是大于属内物种之间的差异。这强调了感染形态在真菌分类学描述中的作用，而真菌分类学描述通常仅限于孢子的特征。提供了可用于区分地下三叶草根部内这 10 种真菌的特征的关键。
The anatomy of vesicular-arbuscular mycorrhizas formed by 10 species from the Endogonaceae within subterranean clover roots was compared using light microscopy. In pot cultures of single species of fungi, each fungus formed a characteristic infection pattern within roots of subterranean clover. Fungi from the genera Glomus (excluding G. tenuis), Acaulospora and Gigaspora were readily distinguished from each other. Within each genus, species varied in the extent to which they formed hyphae or vesicles with dissimilar morphology. Differences among genera were always greater than those among species within genera. This emphasizes a role for infection morphology in taxonomic descriptions of the fungi which are usually limited to features of spores. A key is provided to the characteristics useful for distinguishing among these 10 species of fungi within roots of subterranean clover.
