Encrusting red algae on rocks exposed on a low spring tide in Scotland.
No interactions present.
A long wait; but I now agree. Reading all that's available, particularly that it is difficult to ID in the field but with these plates and ridges and small raised areas, on rock, you could be right. I hope so, as I have agreed.
Now, take a look at this
According to MarLIN it will grow on holdfasts, so why not surge-thrashed lower stems?
"Calcified smooth pink or greyish pink crusts on rock, shells and holdfasts. Convoluted ridges present where neighbouring crusts meet. May become bleached when exposed to strong sunlight."
I have another excellent potential specimen which I will post in the next few days.

Thanks. These really are tricky to be sure of as the growth forms/colours seem to vary so much in different circs and there are some "very similars" out there. Yours may well be the same sp. but I'm losing faith in my ability to be sure of coralline IDs unless they fit the "classic" descriptions exactly, and even then there's a little doubt!
