Sea chervil / Finger bryozoan / Sea mat  (Alcyonidium diaphanum), a  colonial bryozoan growing on rocks exposed on a low spring tide, North Berwick, East Lothian, UK, July
Description:

I found extensive colonies of these fleshy bryozoan colonies on a shaded rock face exposed on a very low spring tide in Scotland. I think it has to be an Alcyonidium sp. and diaphanum is the commonest and my pics match some forms of this species I have found photos of (form and colour varies a fair bit,...) eg http://www.aphotomarine.com/bryozoan_alcyonidium_diaphanum_sea_chervil.html

Alcyonidium diaphanum

Hayward and Ryland 2003 (Handbook of the Marine fauna of NW Europe) say "a taxonomically difficult family ... most of which are difficult to identify. Three species are readily recognized", and A.diaphanum is one of them. So I agree with your ID.

Bryozoa

Thanks Jo - It was new to me and I thought it might be a soft coral at first - like small dead men's fingers, but after extensive googling, I think this is the most likely.
