Encrusting, gorgeous off-pink and hard algae. Mostly found on rock but here shown on Kelp stalk.
The 'limpet' in P1 seems to be engulfed.

i think..

...pic 3 is definitely phymatolithon purpureum and possibly 4, not sure about the first 2

see some of the postings

and

both verified by expert algologist (from NHM)

worried

You could be right - I was worried.
You do seem very confident!
But I see that you have no agreements to yours (only 'expert' confirmation) - nothing new in that of course!
I will reconfigure and remove the last two pics.
..............
So, for anyone coming here - goodness I hope someone else DOES, then two pictures of crusty red algae on rock have been removed

if you're..

...happy to share these pics - I can get my expert NHM algologist to confirm these (he's been with the natural history museum as an algologist for approx 30 odd years and is a renowned expert on seaweeds). I am lucky because he lives 2 miles down the road and is approachable.

Up to you - it does mean an almost certain ID - he is also amenable to 'I don't know or I'm not sure' - which in my book is always reassuring as most of us are probably not sure if we're truthful.

I am also intrigued why you are "I'm sure as I can be" when these encrusters are little horrors to be sure of at all. You have obviously come on quicker than I have - but that's no mean feat..

as soon as you get ...

...expert confirmation - everyone runs away. They thought they were the experts and unfortunately none of us are.

opt

Yes please, check your email again soon as the pictures are there waiting for you.
I changed my tune recently from showing lack of confidence to being, well, more certain!
To be frank, I don't think it matters much which you opt for, except to say we should be more confident!

Ian

says yes to these 2 pics although not 100% because he would of liked a sample to look at, so you have my agreement

Thanks

Well, that Ian for me please. Looking back I wish I'd've spent more time in those beds and must wade out again this coming year. I suspect there will be a lot of mysteries!
