I enjoyed an excellent introduction to dune slack bryophytes today, organised by Hannah Shaw of Freshwater Habitats Trust and led by Sam. Despite not finding any Petalophyllum there were plenty of highlights.
One of several splendid fruiting patches of Amblyodon dealbatus (thanks to Barry for the tip on where to find it).
Several thalli of Moerckia flotoviana found by Sam at SS78738194 (first site record since 2012?).
