This one has been frustrating me as it does not key out using Smith. Although I'm suspecting it's just a robust, falcate form of Campylopus flexuosus, I'm posting it in the hope someone will correct me and tell me it's something much nicer, but I'm not too expectant. For ref it was growing below Sgwd Clun-Gwyn Isaf on a dry (but obviously humid), north-facing rock face (SN92311059), with associates such as Hymenophyllum tunbridgense, Scapania gracilis, Diplophyllum albicans, etc. Sunday's excursion was not a bryologising trip unfortunately, but there were plenty things of interest I noted along the waterfall loop. There was nothing that hasn't been recorded previously, but hopefully a few additional centisquare records will help with documenting the riches of this lovely valley.
