Fan-shaped diatoms colony

#1 Post by Glycolyse » Sat Feb 02, 2019 5:51 pm

Hi everyone,

I came across this beautiful organization of diatoms attached to Ulva lactuca (green Mediterranean algae).

What is the Gender & specie of these diatoms ?

Part of the fun in microscopy is attempting to identify the organisms you find. Any suggestions, guesses, inquiries based on your own research?

Looks like it might be Licmophora sp.

(sp. means that the species is not identified) Generally just getting to Genera is considered pretty good.

Indeed, it looks like Licmophora sp. After some research, it could be Licmophora flabellata.

Thought for a brief moment that you had taken a giant leap in your photo-microscopy skills ;)

Now that you know what can be done ... hope it inspires you!

Thanks 75RR for the links ! I actually tried to make one 2 days ago from cardboard, it was a complete mess :roll: Do you have a picture of a genuine one ?

You should be able to download the pdf ... and then print them on Inkjet Printable Transparency Film

Your local photocopy shop should be able to do it.

Your original photo is quite good and it looks like your research skills are better than you may have thought!
