Minor point - Cwm Clydach is in VC42. Nice pic of the Scapania.
Thanks - that's what happens when I step over the boundary, I become all disorientated ;-)
It's not helped by Clydach being in Gwent and modern day Monmouthshire. Like Trefil it's in vc 42 though.
Thanks for continuing to post the photos Barry - they are really useful for me in terms of helping to know what to look out for, particularly for species I've never recorded like S. compacta.
