Knowing the extraordinary biological and economic significance of arbuscular mycorrhizal fungi (AMF) and also due to the satisfactory results reached with the vast field application of two strains, INCAM-2 and INCAM-4, from AMF collection at INCA, this work was aimed at their taxonomic reclassification, taking into account the availability of a single and reliable molecular technique, as well as worldwide experts´ advice on this fungal morphologic characterization. So far, these strains have been known as Glomus clarum-INCAM-2 and Glomus fasciculatum-INCAM-4. The detailed spore observation at the microscope allowed identifying AMF INCAM-2 strain as Glomus mosseae, which was molecularly confirmed. INCAM-4 strain was just morphologically characterized, suggesting to be classified as Glomus hoi-like, since its characteristics do not coincide with any described species; however, they are similar to those of G. hoi considered as a new species, whose identity requires deeper molecular studies.
