So far, I have found Rhizamoeba clavarioides exclusively in the top layer of mud in the Simmelried and only up until the year 2014. After that, I have not found any more specimens.

Under the coverslip, Rhizamoeba clavarioides usually takes on the monopodial limax form. In this form, movement is fast. Key features of Rhizamoeba clavarioides are the uroid, with very thin trailing filaments, and the irregularly shaped nucleolus in the oval or ellipsoid-shaped nucleus (s. figs. 1 c and 2 a-b). These features allow Rhizamoeba clavarioides to be distinguished well from other species. The similar species Rhizamoeba coerulea is larger, measuring 150–260 µm, and also has multiple nuclei with irregularly shaped nucleoli.

Sometimes specimens of Rhizamoeba covered with detritus are also found. Usually, in these specimens, the nucleus is not clearly visible and identification is difficult. However, after placing the coverslip, the specimens mostly leave this protection, allowing for closer examination.
