Surface detail of the peritrich ciliate, Pseudovorticella chlamydophora (Penard, 1922) Jankowski, 1976. Pseudovorticella is distinguished from Vorticella by silver staining which reveals a lattice-like silver line system in the former and circumferential lines without vertical connections in the latter. Pseudovorticella also has two contractile vacuoles. P. chlamydophora is distinguished by a distinct hyaline layer consisting of large cuboid pellicular blebs. The lattice-like pattern of these blebs is visible here. Feeds on bacteria. From freshwater pond near Boise, Idaho. DIC.
