A water sample was collected from the shore of Srednerogatsky Pond. The air temperature was 14°C (57.2 °F). The sample was kept at room temperature until it was assayed 7 days later.

Mag. 400x
Proportions: 100µ x 22µ; 8-9 striae per 10µ at the center. The size and unique shape of this Pinnularia put it within the range reported for Pinnularia undula var, major as seen here https://diatoms.org/species/pinnularia-undula-var-major. (It is larger than visually-related P. undula). This species is currently not in the iNat database. The second image captures a transition from girdle view to valve view.
- A water sample was taken on 5/8/2023, from the shore of Lantern Hill Pond, using a 10µ dip net to enrich for microbes. Air temp. 73°F.

Suku CymbopleuraHavainnoija

Mag. 400x
Freshwater, asymmetric diatom. The 3 photos in image 1 depict a small rotation around its longitudinal axis. Based on its uniquely large size (180µ L x 50µ W), apiculate and capitate apices, striae count per 10µ (7 at the valve center and 9 near the apices), this specimen (to my eyes) looks like Cymbopleura inequalis. For more information and reference photos see https://diatoms.org/species/cymbopleura_inaequalis and https://www.algaebase.org/search/species/detail/?species_id=q6409a9e46e8376c6.

Photos are courtesy of Jeffery Stone who let me pilot his SEM briefly yesterday. I am not sure where the population was originally from but this is a starfish that was in the Indiana State University marine aquarium.

NOT N. bisulcatum, except maybe the first 3. N. bisulcatum sensu strictu has a width range of 8-9 microns. The majority of the specimens here are a similar taxon that has been erroneously lumped into the species concept of N. bisulcatum by many authors over the course of the last century.
Scale bar = 10 µm.

Found alive and well in a culture in our incubator neglected since the onset of the pandemic. Interestingly enough, some cultures contained dead tardigrades and live rotifers. Source material was antarctic algal mats. Photo taken using darkfield.

Found in an alpine rock pool. photos taken at 400x total magnification. Another type of colonial motile green algae. It appears to be morphologically distinct from the other taxa I documented here. I have a photo of the two taxa next to each other if anyone is interested.

Featureless transparent disks under PPL, but black interference crosses which maintain their orientation when the stage is spun appear under cross polarized light. The interference crosses may separate in some (typically larger) loricae forming patterns like the stitches on a baseball as the stage is rotated.

This was the only specimen of this species present. It was a bit on the small side at only 62 µm in diameter. Note the 2 ocelli and rimoportulae.
Sample was collected from a knothole in a tree.

This is a really fun one. This genus is known to frequent aerial habitats such as cave walls. This population was found in a small knothole full of water. I suspect this is NOT O. roeseana, this population is smaller than published dimensions. The diameter ranged from 13.6 - 24.7 µm. I have seen this species in another knothole.

Just a fun collection of diatoms present in my family's farm pond. This plate represents less than a quarter of the taxa present. If you have questions about any of the specimens feel free to ask. All are to scale, and the scale bar = 10 micrometers.
