Hi,

Daniel,

Welcome to the forums! :D

I personally do not know much about desmids, but I expect some of the members here can help with your search. Your photograph is excellent.

Again, welcome aboard!

Greetings Daniel!

I see that Bernhard has already provided the desmid links that I am familiar with.

Hope you will be posting regularly, it woulds be great to see more of your work.


Your screen name sounds slightly familiar to me... have I lost a few Olympus eBay auctions to you? :wink: :wink:

Charles,
yes my screen name is near my ebay name!
sorry for competition. We are not many to look for BH accessories and I read often the same ebay name!

Congratulations for your pictures in your website. All the pictures are beautyful
Best regards
Daniel

Hi People,

I've just registered after a couple of years lurking in the background and admiring all your work. Some really wonderful photos, some technically impressive, some beautiful, all interesting - thank you. I hope to post a few of my own photos soon.

Daniel, I don't think that it is Pleurotaenium ehrenbergii but rather P. trabecula. There are a few clues. P. ehrenbergii usually has more undulations in the middle and then straighter sides. The key is the cell end, P.ehrenbergii has flattish cell ends (yours are rather rounded) and the definitive feature (which appears to be absent in your specimen) is that it has a number of tubercles / bumps on the cell wall at the ends.

A great web resource for desmids are the plates of West and Wests 5 volume book on the desmids. The book is about 100 years old, so a lot of the names have changed, but the pictures are great. The plates (which are searchable ) are hosted at the royal botanic gardens edinburgh website ( diatom images are also available there).

Keep looking down,

Hey Brian, you are welcome too! :D
The meaning of beauty is in sharing with others.

P.S.
Noticing of my "a" and "the" and other grammar
errors are welcome. :D
