Concerning message #21735:

Dear Bill & Nishina,

For the food of Costasiella pallida I had a Danish phycologist, the late Dr. Tyge Christensen, who was considered a world expert on Vaucheria, identify the alga. The name he came up with was Vaucheria vipera. The food of C. coronata was only identified as Vaucheria sp., but both of these species live intertidally on mangrove mudflats, and the algal patches look exactly like those harboring Alderia modesta in Europe (Kees Swennen is from the Netherlands and has studied Alderia many years ago). I am a little confused about Nishina's assignment of Pseudochlorodesmis to the chromophytes (where certainly Vaucheria belongs). Is this a mistake or has algal classification changed?

Best wishes,
Kathe

Thanks Kathe,

Let's see what Nishina has to say. I am not an expert on algal classification either but I think I would have heard if those to major algal groups had merged. I assume Nishina's use of chromophyte was a mistake for chlorophyte. 

Best wishes,
Bill Rudman
