Another simple and very common seaweed, or so it seemed. Cluttering and massing epiphytically at the joints and stems of Egg Wrack (Ascophyllum nodosum) this looks quite brown, is a little brittle and with quite pointed ends. It is distinctly banded.
In the field, I had it pinned down to a Siphon Weed (Polysiphonia - say the expected P.lanosa ) UNTIL I looked in the Binoscope.
It then became a Ceramium and perhaps even C. virgatum. But then, to be certain, I followed up for a proper ID . A mistake!

26th Added Picture 6, which shows that Pincer Weed not only clusters at forks and joints but also seems to grow from the bladders themselves. See comments.
