A Synura with a very granular cytoplasm. One or two flagella per cell (marked with "F"). This specimen was photographed on the same day the water sample was taken. I'm speculating that the vesicles are not oil droplets which I've seen when viewing specimens from water samples that have been held for days at room temperature. (Stress response to nutrient depletion.) That said, I have no idea why these cells are so granulated.
Observation is from a small sample of water taken from a quillwort pool on a Granite Outcrop with permission from the site managers. pH of the water was tested and was 6.60. 1000x
