...at least I presume it's a Brachythecium and I hope I'm not missing something obvious. It was growing in a grave plot at Morriston Cemetery along with Rhytidiadelphus squarrosus and Calliergonella cuspidata. The falcate leaves suggest velutinum, but the remnant setae all appear smooth, plus the nerves lack an apical projection. The budding on the stem also seems odd? Any thoughts welcome.
