Guardian lead picture; BBS has this: Biantheridion undulifolium
(Nees) Konstant. & Vilnet
Biantheridion undulifolium (was Jamesoniella undulifolia), Marsh Flapwort, growing through Sphagnum rubellum.
Photographed by Des Callaghan during a survey of a site in mid-Wales. It seems quite fussy about which species of Sphagnum it grows through, and was predominantly found with S. rubellum at this site.
