Zoopage
ZOOPAGE Drechsler, 1935 (Mycologia 27: 30), 10 species (Drechsler, 1935).
Predaceous on amoebae and, less commonly, rhizopods. Trap host by secretion of a sticky substance. Haustoria produced in the host, vegetative and reproductive hyphae produced externally. Propagules produced on relatively short sporangiophores. Merosporangia multispored, simple or branched. Spores fusiform, long-fusiform or falcate, wall smooth or rough; spore appendages not formed but one species with empty cells. Zygospores more or less globose, with a cupulate zygosporangium; suspensors hyphoid, more or less equal.
Type species: Z. phanera

Zoopage is a haustorial parasite of amoebae and testaceous rhizopods that trap hosts by an adhesive. These fungi are characterized by the formation multispored merosporangia on relatively short sporangiophores. Zygospores have undifferentiated suspensors and they have cupulate ornamentation (Drechsler, 1935). Merosporangia can be simple or branched as in Z. tryphera (Drechsler, 1937). Merosporangia of Z. mitospora can be observed by scanning the culture with a microscope before application of a coverslip (Drechsler, 1938). A diagram of branched merosporangia as they appear in culture has been presented for Z. pachyblasta (Drechsler, 1947). Empty cell segments are produced in the spores of Z. toechospora, a characteristic unique to this species.
