Indoor mosses

I found Pseudotaxiphyllum elegans with ripe capsules in an orchid pot in a friend’s house today. At least I assume this is what it is, as while I don’t think there’s anything else that’s native it could be, there’s always the possibility of it being an alien import? The plants appeared smaller than typical elegans to me plus I couldn’t find any branchlets in the small sample I collected.

Also, last weekend I saw Leptodictyum riparium in fruit and growing well in the indoor water display at Wyevale Garden Centre in Llansamlet.

Pont-lliw breakers yard

Part of yesterday was spent in the lorry breakers yard in Pont-lliw doing a walkover inspection to check for signs of Otters and bats! This gave me the opportunity to do some less rushed bryo-recording than of late and I managed to log 66 taxa at the site. 17 were new to SN60A taking its total to 113. There was nothing to get particularly excited about, the most prominent species being both Barbula convoluta vars, Didymodon fallax and Cratoneuron filicinum. The slightly more interesting records included:  

Two small patches of Climacium dendroides in the yard area and Amblystegium serpens found this engine block to it's liking:

Cryphaea heteromalla was growing luxuriantly on some concrete pipe sections:

Leptodictyum riparium was growing well and fruiting on old tyres in a ditch:

However, this Archidium-sized moss defeated me and I wonder if anyone has any suggestions? It was growing on almost clay-like duff. I’m suspecting it’s young growth of something familiar, but I can’t place it. The strong nerve extends to just below the leaf tip.
