Diagnosis Test free, ovoid to fusiform, about 0.13 mm to 0.7 mm in length and 0.23 mm to 0.5 mm in breadth, ovoid to circular in transverse section; wall with inner hyaline layer and outer opaque layer of fine agglutinated mica flakes and diatom frustules, resulting in a granular surface; aperture terminal, with entosolenian apparatus of a diameter about one-fourth to one-sixth of the test diameter, connected to the inner wall layer by thin lateral lamellae, during gametogenesis the main aperture constricts and closes, and a ring of accessory apertures forms around it to provide egress for the gametes; gamont uninucleate, schizont multinucleate, with up to 16 nuclei of 12 µm to 86 µm in diameter; cytoplasm gray to colorless.
