Chaos spec. – the lighter spots are nuclei

Chaos spec.

Nuclei almost spherical with small pieces of nucleolar material laying close near the nuclear membrane and some other pieces more centrally arrangend. About 10 nuclei were present in this specimen.

Dimensions: monopodium 450-550 µm; nuclei 15-30 µm. n=1

Ecology: Crailoo, very shallow water between Fragmites australis (common reed), together with Enteromyxa paludosa, Clathrella foreli, Reticulomyxa filosa and Hyalodiscus rubicundus.
