Filled with Zoochlorellae, like Acanthocystis turfacea and A. pernardi, both found locally. However. this specimen is very different in that it is covered with loose, elliptical scales (5-10µ in length). I do not see any spine-scales. The long axipodea are very granular and are, occasionally, piled high from the base with elliptical scales (40-50µ high!). The elliptical scales form a disorganizes, 10µ thick layer enveloping the entire protoplasm. The best candidate (by my eye) for an ID, at Siemensma's Microworld, is Raphidocystis ambigua https://arcella.nl/raphidocystis-ambigua/. A 2nd possibility is R. symmetrica https://arcella.nl/raphidocystis-symmetrica/, but the current specimen is much larger than those recorded by Siemensma. No reference to Zoochrorella is made in describing either taxon. I could not find a match among the Acanthocystis.

I think this is Raphidocystis pallida, because of the similarity of these 4 specimens to images here https://arcella.nl/raphidocystis-pallida/. The stacking of scales against the base of some of the axopods gives them the look of tall pine trees (https://en.wikipedia.org/wiki/Centrohelid). For an interesting video that records the movement of the central ectoplasm, see https://youtu.be/VfGL6os0Icw.
I say no, no, no . . .
