Harpalejeunea new for Pembrokeshire

Matt Sutton's continued scouring of VC45 for species missed during recording for Mosses & Liverworts of Pembrokeshire has produced yet another excellent record. Harpalejeunea molleri on a rock by the Afon Tewgyll, south of Carn Meini is the first of the desiccation-sensitive trio of Aphanolejeunea, Drepanolejeunea & Harpalejeunea to be seen in Pembrokeshire.  Whilst Colura is now commonplace, the other three species remain extremely rare in the southern half of Wales, and the nearest locality for Harpalejeunea is in NE Carmarthenshire.  I checked some stretches of the Afon Tewgyll about 12 years ago, but never dreamed of Harpalejeunea!
