Mayorella sp. - Microworld

Mayorella sp.

Diagnosis: locomotive form elongated, with the length always greater than the breadth; mammilliform or conical subpseudopodia, often overtaken by the advancing hyaloplasm; nucleus spherical, with a central nucleolus; endoplasm densely filled with small granules which make it very difficult to detect any other content, like crystals.

Dimensions: c. 150-180 µm; c. nucleus 12-19.9 µm (n=8).

Ecology: forest soil, Southern France.

Remarks: it is hard to tell if the dense mass of granules is a taxonomic character. All observed amoeabe look the same.

Mayorella sp., 155 µm and ingested diatoms

The ectoplasm contains a large number of granules of different size.
