Mayorella viridis
M. viridis, Netherlands, 2020

Mayorella viridis  Leidy, 1874

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; no cytoplasmic crystals observed; endoplasm with zoochlorellae.

Dimensions: Page: 90-160 µm; nucleus 9-15 µm. My measurements: 80-160 µm, nucleus c. 12 µm.

Ecology: Freshwater, usually in Sphagnum bogs, but also in other wet mosses. I also found them in a glacial stream in El Chalten, Argentina.

Remarks: The name “viridis” refers to the typical green color, caused by the zoochlorellae.
