I think these are probably Anthoceros agrestis, given the rosettes are small (0.6-0.8cm diameter) and this species is more likely than punctatus in the east of Wales, but I couldn't find any antheridia to confirm this. Any comments on whether it is safe to record this as agrestis would be welcome.

There was also a lot of Fossombronia sp. (lacking sporophytes) as well as Tortula truncata, Trichodon cylindricus, Dicranella staphylina and Bryum rubens, among other more generalist species such as Oxyrrhynchium hians.
