The Fascinating World of Amoebae
Nucletmycea Brown et al. 2009
This is a group that includes Fungi, Nuclearia Cienkowski 1865 and Fonticula Worley et al. 1979. Some nucleariid amoebae often show axopodia-like pseudopodia. Nucleariids have no axonemes and no kinetocysts.

1. Nuclearia Cienkowski 1865
Amoeboid with rounded body, from which elongated filopodia extend. Often surrounded by a mucous layer with bacteria.
