I was back in the Ewenny area today and like Sam spent my lunchbreak doing some recording. In the Entodon post I mentioned a limestone crag on Old Castle Down which was crying out for a closer inspection, and this occupied my entire lunchbreak.
The crag is west facing and sits on the shoulder of the down at SS898759. Working south I'd found little of interest by the half way point, but then close together were two smallish patches of Entosthodon pulchellus on soil-capped ledges (posed for this photo on garden soil at home...I took a sample as I wasn't sure of the species in the field). Associates included Trichostomum brachydontium and Fissidens incurvus.
There was nothing else of particular note, but small amounts of Pleurochaete squarrosa, Plagiomnium affine and Eurhynchium striatulum are perhaps worth mentioning.
I've downloaded some more photos from the cheapo work camera - not the best but gives an impression of habitat and microsite. If the latter is blown up there are at least three fruiting plants (red circles) and what looks like quite a few non-fruiting plants among the Trichostomum brachydontium cushions.
