A new species of arbuscular mycorrhizal fungi, Glomus candidum is described. The species produces spores singly in the soil. Spores are white to very pale yellow, usually globose to subglobose, 87-157 μm diam. Spore wall consists of two adherent layers. The outer layer is hyaline, mucilaginous, and stains very pale pink in Melzer's reagent. This layer can be observed in young spores and often degrades at maturity. The inner layer is hyaline and laminated, but occasionally the innermost group of laminae are pigmented a pale yellow to give the impression of two separated layers. Resumen — Se describe una nueva especie de hongo formador de micorrizas arbusculares, Glomus candidum. La especie produce esporas libres en el suelo. Las esporas son blancas a amarillo muy palido, usualmente globosas a subglobosas, 87-157 µm de diametro. La pared de la espora consiste en dos capas adherentes. La capa externa a menudo se degrada con la madurez, es hialina, mucilaginosa, y se tine, solo en las esporas jovenes, de rosado muy palido en reactivo de Melzer. La capa interna es hialina y laminada, pero a veces el grupo mas interno de laminas aparece pigmentado de amarillo claro dando la impresion de dos capas separadas.
