Churchyards provide habitat for a number of bryophytes that are rare or absent from the typical farmed landscape of lowland Monmouthshire, including rock-dwellers like Racomitrium aciculare (which is quite frequent on flat sandstone gravestones), woodland species like Cirriphyllum piliferum and Rhytidiadelphus triquetrus, unimproved grassland mosses such as Pseudoscleropodium purum, and acidophiles including Dicranum scoparium. The last of these can be abundant on graves surfaced with acid gravel, as was the case at Llanddewi Rhydderch where I took the photo above.
Tetrad recording in the Llanddewi Rhydderch square (SO30L) produced just over 50 rather mundane species. Highlights away from the churchyard included a few epiphytes in a lane, with a single tuft of Orthotrichum anomalum (sadly with all but one of its capsules slugged, so I can't be 100% certain it wasn't O. consimile) being the most unusual record. Anyway, this is another tetrad ticked off the list, leaving 101 which I haven't yet visited.
