Saccamoeba clava
(Schaeffer, 1926)

Saccamoeba clava Family: Body monopodial; locomotion by slight forward bulging (Illustrated Guide, 1985).
Genus: Limax amoebae with hyaline cap reduced to shallow crescent or absent in continuing locomotion, though always seen on initiation of pseudopodium; advance often with non-eruptive slight antero-lateral bulging; villous-bulb uroid with more or less rigid fine villi often present (Page, 1976).

Species: Monopodal, 75-125 μm; pseudopods, more or less eruptive; uroid, temporary, of gnarled filaments, 10-15 μm long; ectoplasm smooth; nucleus spherical 14 μm with endosome distinct 8 μm (Illustrated Guide, 1985).
