A). The nucleus is a folded or approximately round in shape and is located within an exonuclear vacuole. A vacuole, up to 100 µm wide; is sometimes located in the center of the nucleus. Pseudopodia have not been observed but a thin string of cytoplasm projects through the centre of the peduncular sheath, along its central axis. However, examination of the cell body of critical-point dried individuals by SEM reveals a dense network of cytoplasm organized like fine pseudopodia (reticulopodia), in which are embedded stercomata, mineral particles, and other foreign inclusions (
