Micrographs of three closely related new species of subgenus Paraphysomonas from soil, showing stomatocysts of differing morphology: Paraphysomonas spiculosa terricola, P. spiculosa spiculosa, P. spiculosa edaphica.(A, B)P. s. terricola. (C – E)P. spiculosa spiculosa. (F)P. spiculosa edaphica.(A) DIC of live P. spiculosa terricola cells with just visible scales (arrowhead) and plugged stomatocyst (*). (B)P. spiculosa terricola TEMs of detached scales. (C) DIC of live P. spiculosa spiculosa cells, one dividing (%) and plugged stomatocyst (*). (D, E)P. spiculosa spiculosa TEMs. (D) Scales attached to cell surface. (E) Side view of scales and cilium hairs (**) and single scale including close-up of spine tip (box). (F) DIC of live P. spiculosa edaphica motile cell with cilia (on right), smaller more shrunken cell at top left (perhaps starved, apparently non-ciliate) and stomatocyst (*). Scale bar: A, C and F, 5 μm. B, 0.5 μm. D and E, 1 μm.
