Leptobryum pyriforme, Jersey Marine
I've only ever seen Leptobryum pyriforme in a flower pot before today so I was pleased this afternoon when we found large amounts of it on a weedy bank on the Amazon site in Jersey Marine. It appears to be uncommon in Glamorgan and Wales in general, yet it has a globally widespread distribution in temperate and boreal ecosystems. Non-fruiting material might go unnoticed in ruderal communities among lookalikes such as Trichodon cylindricus and Dicranella schreberiana (also on the Amazon site). In fruit, with those Bryum-like, pear-shaped capsules, it is unmistakable.
