Yesterday lunchtime I took the short drive over to St Fagans to record a few more species in ST17I, where the existing total on Barry's latest map was 30 species. I spent a while in the churchyard and found a good range of common species but nothing unusual.

Grimmia pulvinata was probably the most abundant species on gravestones.
There was also a surprising amount of Dicranoweisia cirrata on presumably more acid stones, and one small patch of Frullania dilatata on a granite (?) grave. I see that Sam mentions in his Pembs flora that it was recorded 12 times on graves in that county.

I made a brief diversion into a nearby woodland which had some promising-looking limestone outcrops, but almost every stone, log and tree base was smothered in Thamnobryum alopecurum, leaving little space for anything else.
I did eventually find a couple of patches of Anomodon viticulosus, and this small Fissidens which was growing through wefts of Amblystegium serpens on thin soil over limestone.
It is not very clear from the photo but the one nearly mature capsule I found was inclined and the leaves were bordered. I was fairly convinced this was F. incurvus, but I'm puzzled by the seta arising from the base of the stem rather than being terminal. Also, the young sporophyte in the photo arises laterally rather than terminally. Maybe I'm being dim, but I thought all the bordered leaved species had terminal setae?
