A belated post from an outing on 23 March -
My first full day of bryophyte recording in I don't know how long took me to ST09, one of the more under-recorded hectads in Rhondda Cynon Taf with only 4 of the 25 constituent tetrads having 60+ bryo species recorded.
I started at Tylorstown Tip (aka Old Smokey), which despite being such a prominent Rhondda landmark didn't appear to have any previous bryophyte records.
After lunch I moved on to the southern end of the Llanwonno forestry plantation, where ST09G was a blank canvas as far as bryophyte recording goes. Rotting conifer logs among the Sitka held plenty of Nowellia curvifolia, Calypogeia muelleriana was found on a ditchside, Colura was recorded on birch and rowan and Ulota calvescens on willow (but no Daltonia was forthcoming despite actively searching for it). A puzzling Metzgeria with very narrow thalli was also found on willow (see photo below - note the Frullania which gives a sense of scale). This might be the male shoots of M. furcata mentioned in Paton but if anyone has any other ideas please let me know.
