Pussard and Pons 1976 sensu Smirnov et al. 2017
Naked amoebae with locomotive form altering from a flattened expanded or reticulate one to a subcylindrical monopodial one when in rapid movement or under specific conditions; able to form an adhesive uroidal structure, no differentiated glycocalyx.
Simple life cycle, cyst —> trophozoite —> cyst. Sex or fuiting bodies are not know in this group. Found in freshwater, seawater and soil.
Leptomyxid amoeba
Leptomyxid amoeba
Leptomxid amoeba are comon but easily overloooked as they ususally hide under detritus. Although it is normally not difficult to identify an aboeba as a Leptomyxid, it is most often impossible to determine the genus or species at the morphological level.
Goodey 1915 sensu Smirnov et al. 2017
Amoebae of various shape, from limax-like to branched, expanded, reticulate plasmodia-like organisms. Low-mobile or non-mobile cells can adopt expanded, comet-like shape. Various numbers of nuclei – from one to several thousands.
Schaeffer 1926 sensu Smirnov et al. 2017
Amoebae in locomotion flattened, flabellate, with prominent anterior hyaloplasm irregularly triangular or fan-shaped. Limax form adopted only under unfavourable conditions. Uninucleate or possessing few nuclei.
Page 1972 sensu Smirnov et al. 2017
Amoebae altering locomotive morphology from limax-like to flabellate, fan-shaped and possessing collosomes in a single studied species. Uninucleate or possessing limited number (less than 50) nuclei. Cells never adopt expanded, comet-like shapes.
