豆形埃希氏菌在各种正常的真菌培养基上进行了纯培养。通常共核细胞的菌丝体呈典型的黄色，并带有大量充满脂质的菌丝肿胀。在无菌条件下，菌丝被炭疽菌吸引，但真菌既没有在炭疽菌上萌发孢子，也没有寄生在炭疽菌上。豌豆根霉虽然可以在根际环境中存活，但在接种的条件下不能形成外生菌根。萌发的猪笼草和洋葱种子、枯死的根和枝条被豆形埃希氏菌侵染，在这些植物组织中形成密集的分枝细小的菌丝结构和充满脂肪的菌丝肿胀。提出了这些结构与泡状丛枝菌根真菌的丛枝和小泡同源的可能性。对其他Endogone种的研究可能有助于阐明该属的系统发育。
E. pisiformis is described in pure culture on various normal mycological media. The usually coenocytic mycelium is characteristically colored yellow and bears numerous lipid-filled hyphal swellings. Under axenic conditions, hyphae are attracted to Sphagnum, but the fungus has neither sporulated on nor parasitized the Sphagnum. E. pisiformis does not form ectomycorrhizae under the conditions studied with inoculated P. sylvestris although the fungus may survive in its rhizosphere. Germinated A. porrum and A. cepa seeds, moribund roots, and shoots were colonized by E. pisiformis which formed densely branched, fine hyphal structures and lipid-filled hyphal swelling within these plant tissues. The possibility is raised that these structures are homologous to the arbuscules and vesicles of vesicular-arbuscular mycorrhizal fungi. Examination of other Endogone species may elucidate the phylogeny of this genus.
