I was planning to try to find the Entodon concinnus colony at Ogmore Down (recorded by Chris Forster Brown in 2012) after a site meeting there this afternoon. As it turned out I didn't need to. The person I was meeting was late so I spent a few minutes poking around on the south-facing slope near the parking lay-by, and there it was. I went back after the meeting and found several small patches spread over an area of perhaps 25 x 25m, but further searches on the lower slopes failed to reveal any more.
Although it looks quite distinctive in this photo I don't think I'd have spotted it if I wasn't looking out for it - I'd probably have overlooked it as a slightly stunted, brownish Pseudoscleropodium purum (which is much more abundant on the same slope). Once I'd got my eye in the slightly less blunt shoot tips, combined with narrower shoots and bronzy appearance, meant it wasn't too hard to spot. Close associates in the limestone turf included P. purum, Homalothecium lutescens and Hypnum lacunosum. Not too far away were Ditrichum gracile, Neckera crispa, Ctenidium molluscum and Pleurochaete squarrosa.
The location is about 400m east of Chris's grid reference. I can send more specific directions via email if anyone wants to go and see it, though it is likely to be in other places on this slope too. A few more photos below.
