Looking at the tetrad list yesterday morning it was obvious it hadn't been 'grotted', with only two Didymodon species on the list and no Syntrichia. Surprsingly there were only two Orthotrichum species recorded too. This seemed a good excuse to take the kids to the playground in Pentyrch yesterday, which proved a bit more interesting than expected as there were some small limestone outcrops just outside the fence.
The visit added 10 species to the tetrad list taking it past the 150 mark; four of these were on a Sweet Chestnut (Orthotrichum lyellii, Hyp. cup. var resupinatum, Syntrichia papillosa and S. laevipila), one on concrete steps (Didymodon luridus) and four on the limestone outctrops (Orthotrichum anomalum, Barbula sardoa, Didymodon sinuosus and Bryum radiculosum). I'd be grateful if someone is able to confirm the Bryum from the photos below; I suspect I've been overlooking it until now. Thanks

|The straight leaves and excurrent nerve look right for radiculosum.|
