The Hartmannellidae are a family of amoebozoa,{{cite web|url=https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?mode=Tree&id=5776|title=www.ncbi.nlm.nih.gov|access-date=2009-05-02}} usually found in soils. When active they tend to be roughly cylindrical in shape, with a single leading pseudopod and no subpseudopodia. This form somewhat resembles a slug and as such they are also called limax amoebae. Trees based on rRNA show the Hartmannellidae as usually defined are paraphyletic to the Amoebidae, which may adopt similar forms.
