Delesseria sanguinea

(Hudson) J.V.Lamouroux, 1813


Paul Brazier Strand seaweed from Trearddur, Anglesey, March 2013. Anyone any idea what is going on here? Membranoptera fronds visible, but I think these are epiphytes on the more robust main branches.

Liz Morris i dont know much about weeds and things, but thinking outside of the seaweed box-little aplidiums or infurled athecate hydroids???

Francis StPierre Daly Bunker If I get a chance I will discuss this in the seaweed course tomorrow

Cynthia D. Trowbridge For those of us not there, please let us know electronically (when you get the chance). Have a great time..wish I was there!!

Paul Brazier Thanks Francis - the specimen is going to Porcupine this weekend, so I can put Juliet on the spot!

Francis StPierre Daly Bunker Just thought. What about Delessaria sanguinea?

Paul Brazier Lin Baldock and I put our heads together last weekend at the north Wales ID course and read a bit more of Maggs et al. Tetrasporophyte of Delesseria sanguinea which appear on the old fronds from Dec to April? Whatever next!!

Francis StPierre Daly Bunker That's what I said (read my last post)

Paul Brazier I know you did, I was simply expanding on your comment, sorry not to acknowledge your great wisdom. P

Francis StPierre Daly Bunker Your forgiven. As they say, fools never differ!

Becky Hitchin I continually have traumas with Delesseria sanguinea and Phycodrys rubens. Finally got it sorted on perfect specimens, but could someone tell me if they are distinguisheable on photos like this? Thank you!

Sarah Bowen Most of this looks like Dictyota dichotoma to be honest. The very tatty stuff I'd say is D. sanguinea.

Becky Hitchin Well yes, there's a lot of Dictyota in there! I was focussing on the tatty stuff that could be either Del or Phycodrys. Was wondering if there's a way to tell the difference when it's not beautiful and pristine. Is it only size that would distinguish them like this?
