Description: This amoeboid protist shows a very variable morphology, sometimes more extended and reticulate, at other times slim and stretched. Image shows a specimen of app. 300x300 Âµm including the pseudopodia. Pseudopodia branched, anastomosing and conspicuously stiff, with diameters decreasing continuously from the center to the periphery. There is no distinction between hyalo- and granuloplasm. In parts of pseudopodia close to the central mass a simultaneous bi-directional streaming, centripetal and âfugal, of the granules within the pseudopodia is visible. Numerous vacuoles in the central mass, some also located in the pseudopodia.
