Abstract The fine morphology of the sporocysts of Ascosphaera apis (Maassen ex Claussen) Olive & Spiltoir, an entomopathogenic fungus of the immature honey bee has been studied using the scanning electron microscope. During the third day of mycelial growth in the culture medium, numerous short, branched hyphae were formed. The tip of the branch-hypha gradually expanded to form immature sporocysts. The immature sporocysts contained a large number of globules of varying sizes. The walls of the immature sporocysts were finely wrinkled, becoming smooth as the sporocyst matured. Both exterior and interior surfaces of the sporocyst wall possessed numerous papillae. Some globules in the developing sporocyst began to form immature spores which aggregated to form spore balls. The fully formed spore balls were not enveloped by a membrane.
