I ran into bother today, seeing this for the first time and thinking it was not ordinary - it is!
But it took me a while to get it right.
Growing from both Fucus serratus (Toothed wrack) and Fucus vesiculosus (Bladder Wrack) and a strong, distinctive and slimy epiphyte, sharing space with Elachista fucicola - see https://www.ispotnature.org/communities/uk-and-ireland/view/observation/773622/
Fortunately I bought some home to photograph on the light table.
It is not unlike Cladostephus spongiosus, seen in picture 5 and also Mesogloia vermiculata seen here https://www.ispotnature.org/communities/uk-and-ireland/view/observation/763352/ but distinctive enough to separate.
Possibly another first for iSpot. We really need more seaweeders
