Pepper Dulse
Description:

lower intertidal zone - Recorded in this area but first for me. I'm pushing everyone here as I know people are not great seaweeders (is there such a word?) or macroalgologists as I have loads of postings with no responses. This is Osmundea - Pepper dulse.

Osmundea?

This looks a bit too fleshy and more like Pepper dulse, Osmundea pinnatifida to me, whose form varies a bit with compact or more stringier depending on exposure, but maybe you've ruled that out for some reason?

Nick...

....I had ruled it out on the basis of all the other pepper dulse here is extremely small and even from the october posting (which you have kindly agreed with) it has not increased in size in this area. M.stellatus has been recorded a lot round here and the sporophyte phase P.cruenta is also present close by. The texture was harder than the Osmundea. I was also swayed by a pic in the Seasearch Guide to Seaweeds of Britain and Ireland. So still not 100% sure really, looks a bit fleshy I guess and maybe a big bit of Osmundea.

Tricky seaweeds

I guessed you had good reason to go with another ID, but maybe it's still a maybe unless a real seaweed expert chimes in. I know most of the common ones, but have learnt the hard way how tricky many lookalike red algae (often with variable growth forms..) can be when trying to ID what I've photographed!

I have a guy...

...locally who is with the NHM and is a bit of a whizz on seaweeds, I'm going to try and meet up and go through my pics of seaweeds. I will let you know what happens with this one.

Seaweed whizz

OK thanks. I'll be doing some more shore photography this spring/summer, so will keep trying to improve my ID skills, and seaweeds are the toughest..

Have....

....been to see my seaweed guru and was quite an eye opener. I had done well on most IDed weed but there was a lot that he reIDed for me including this one - his comment was in response to the difference in size to all the other examples around - 'this can happen on individual rocks, may be a nutrient rich flow of incoming tidal water here'.

Tricky seaweeds

Interesting.... and confirms my own impression of just how variable seaweeds can be from site to site and from different heights/ exposures on the same shore... but I hadn't thought of nutrient flow..

as a reference..

...made another boo boo in this posting

This may also help you for your seaweed bit for the future (was IDed by my guru).

Even tricker

The red encrusting ones are the worst... so many similar ones, all varying a lot in growth form..
