At just over 40m a.s.l., Mynydd Lliw is hardy mountainous, nor is it very natural, most of the substrate comprising restored colliery spoil. I've done very little bryologising this week, so I took Alfie out for an hour this afternoon to a part of this site I've not been to before - an area that looked interesting on the aerial images. Following today's downpours, the mosses were luxuriant and it turned out that the brown areas on the aerials were concrete bases dominated by a deep cushion of
Didymodon ferrugineus, with some patches of cf.
D. rigidulus (both species shown together below).
Of the 26 species noted growing on a thin crust of detritus over the concrete, others of interest included - in decreasing abundance - Trichostumum crispulum, Bryoerythrophyllum ferruginascens, Calliergonella lindbergii, Riccia glauca, R. sorocarpa and Tortula modica.
