Add’l Synonyms: n.a.
Sampling date 06/2026. Scale bars indicate 10 µm.
Seven images, six of them in a slide changer.
Members of the genus Serritaenia produce extracellular mucilage with a pigmentation for UV-protection. For details please look at Busch, A., Hess, S.:
Sunscreen mucilage: a photoprotective adaptation found in terrestrial green algae (Zygnematophyceae), https://doi.org/10.1080/09670262.2021.1898677
The cells shown here were attached to Sphagnum leaves.
| First: | Cell colony in its UV protective mucilage. |
| Second and third: | Same colony at a higher magnification. |
| Fourth to sixth: | Detailed views showing chloroplasts, pyrenoids and nuclei. The fully developed cells shown in the image No. 5 have dimensions L = 23.5–24 µm and B = 15–17 µm. |
