Acaulopage Explained

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

Morphology

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

Ecology

Species are often recovered from soil or leaf litter placed on agar in Petri dishes. Acaulopage tetroceros is the most commonly reported species.^{[2] [3]}
