Notes

A mycophagous amoeba from Australian soil was identified as Ripidomyxa australiensis and placed in the order Leptomyxida. It is characterised by flattened branched fan-shaped uninucleate trophozoites which can also be limax at times. Its nuclear division is of the mesomitotic type with the nucleolus disappearing in prophase and it produces cysts which are mostly spherical to oval with a single smooth wall. The systematic position of R. australiensis and its similarities and differences with other members of the order Leptomyxida and Rhizamoeba Page, 1972 are discussed.
