Hi all,
I am trying to identify a diatom that is fairly common in salt marsh samples from coastal Oregon (USA). I believe it is a species of Parlibellus, but I am unable to find a reference to it. It's typically about 40-48 µm long, and 8-10 µm wide. Striae are fine, 18-20 ITM, and more widely spaced at the middle. The central raphe endings are moderately distant and slightly deflected, and the central area is consistently oval shaped.
Thanks --
You're working on identifying a diatom from the genus Parlibellus in salt marsh samples from coastal Oregon. Based on your description (40-48 µm long, 8-10 µm wide, fine striae with wider spacing at the middle, oval-shaped central area, and slightly deflected raphe endings), it appears to align with characteristics of Parlibellus species. However, the exact species identification may require comparison with more detailed taxonomic guides or regional diatom floras. SEM images could also provide further details for accurate identification. Consulting with diatom experts or online databases might help narrow down the species.
Dear Sir, I am reaching out to other diatom experts on Research Gate to give me suggestions. I have already searched all of the available descriptions of Parlibellus that I have been able to find, descriptions that could be appropriate to the region. No luck so far. CALLING ALL DIATOMISTS! Any suggestions?
