A very common red algae and, here, incredibly prolific in the strand-line. A whole range of reds from almost transparent grey-pink to very bright scarlet.
Viewed as originals, the top two photos can just be identified as Cock's Comb - P2 specially. But this is often as much as you get on a beach, without close inspection through a glass. BUT not all scarlet or red weed lookalikes are Cock's Comb.
Close-to Cock's Comb shows 'teeth' (comb) on one side only of the very final twigs; some, not all, samples I collected, showed continuous branching from one side only.
Some of the comb teeth appear to be sporangia in which are 6-8 tiny, regularly shaped and spaced, spore masses - seen in Picture 4.
There are much larger, at first spherical and complete cystocarps, which (appear to) burst and becomes cup-like - Pictures 3&5.
Picture 6 shows the key feature for ID - the Combs.
