Nucletmycea

Brown et al. 2009

This is a group that includes Fungi, Opisthosporidia, Nucleariida, and Fonticula. Some nucleariid amoebae often show axopodia-like pseudopodia. Nucleariids have no axonemes and no kinetocysts.

‚óŹ Nucleariidae

Smirnov, Nassonova, Berney, Fahrni, Bolivar et Pawlowski 2005

Cells with lobose pseudopodia (lobopodia). The entire cell or individual pseudopodia (in polypodial cells) are tubular, cylindrical, or subcylindrical, rounded in cross- section. If cells are flattened or branched they are capable of altering the locomotive form from a flattened, expanded one to monopodial or polypodial, with subcylindrical pseudopodia. Monoaxial flow of the cytoplasm in every pseudopodium or in the entire cell. No ciliate stages. Two groups are testate, and two sorocarpic taxa are known. No sporocarpy has been reported.


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