An amoeba-capturing fungus in the genus Acaulopage (Zoopagaceae) was obtained on a water agar plate that had been incubated with a pinch of moss sampled from the river bank in a canyon of Miaoli County. The fungal material was observed by using a stereomicroscope and DIC microscopy. The Miaoli strain is identified as Acaulopage tetraceros based on morphological characters and represents the first record of Acaulopage in Taiwan.
