Possible Weissia rutilans

On the way back from a site visit to Mewslade today I stopped off in SS48T at Scurlage (a square dominated by arable and little else) in an attempt to add to the paltry 29 species recorded there. I grabbed a sample from a fruiting patch of Weissia with seemingly plane leaf margins that was growing on a bare patch of loamy soil in the centre of the track amongst low grasses. Expecting it to be W. brachycarpa var brachycarpa, I was surprised to find it had a rudimentary peristome when I pulled an operculum off first one then two capsules. The leaves are heavily coated in crud and few seem a little inrolled, so very much a provisional id for now. I'll post some pics later for comments.
