Acaulopage is a genus in the former Zygomycota that preys on amoeba.


Species of Acaulopage are characterized by coenocytic hyphae that have patches of yellowish adhesive patches used to capture amoeba.[2] Conidia are borne directly on the hyphae[1] and vary widely in morphology. Many bear one to many empty appendages.[2] For example, A. marantia conidia have a single appendage;[2] A. tetraceros conidia have an average of four appendages;[1] and, A. lasiospora conidia are covered in appendages.[3] Zygospores are globose with ornamented walls.[2]

Species are often recovered from soil or leaf litter placed on agar in Petri dishes. Acaulopage tetroceros is the most commonly reported species.[4][5]

According to Gerald L. Benny, there are 27 species of Acaulopage.[2]
