Stonewort (Genus Nitella)Observer
smellyturkeyDescription
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.
