Concerning message #22763:

Most of the algal filaments in the photo showing the egg mass are NOT Vaucheria, and I do not see any that I could say for sure are that species. You might reasonably ask what species are they then? - and I can't tell you that from the photo (Chaetomorpha might be a good start, but could be others), but you can clearly see cells in most of them.

Thanks Skip,

I suspected I could see cell walls so am glad to get your confirmation. If the published information on Limapontia depressa is correct, and it only feeds on Vaucheria, then we not only have an identity problem witht yhe algae but also with the Limapontia. To say anything sensible I think we need a photo of the algae at higher magnification and a hunt for the kidney opening. Is it possible that small strands of Vaucheria are living epiphytically on the filamentous green algae?

Best wishes,
Bill Rudman
