Colonial, stalked choanoflagellate on a strand of Eunotia diatoms (in apical view). The feeding cone/collar and central flagellum can be seen on many of the cells in the still photographs and videos.

seemed to be epiphytic on this Nitella specimen, and quite abundant.

Vernal pool. Not certain about the ID but I've found similar images online that seem to be of Chara, but I did not notice this species while searching the pool for alga. Found while examining a specimen of Nitella under the microscope, at 200x-400x magnification.
@roman_romanov Can you explain what the clear squiggles are?

Vernal pool
@roman_romanov while watching the cytoplasmic streaming, I noticed a variety of round shapes circulating. Most were circular and empty-looking, but some looked quite spiky, as in the last photos of this observation. Do you know if it's another endophyte, or just a normal part of the Nitella?

- A pond-side water/periphyton sample was taken 04/22/2024 using a small sample bottled attached to an extension pole. Air temp 61F.
Various forms of Hyalotheca dissiliens. The first 3 images show a mass of H. dissiliens zygospores. These masses are the largest I've encountered and were seen throughout the slide. The 4th image shows a segment of H. dissiliens with cells attached in filamentous form, surrounded by broad mucilaginous sheath. The last 2 images show H. dissiliens in single cell format. Both lateral views (barrel-shaped) and apical views (where the chloroplast has a stellate form) are visible.
