mystery moss in Glynneath!

Re: moss erroneously identified as Dicranum fuscescens in earlier post (doh!)

I don't think it's an aberrant from of Campylopus flexuosus. Although some of the the sporophytes on plants in situ are Campylopus-like and there is a tomentum, the leaves don't have the conspicuous differentiated alar cells of that species or the typical leaf cell structure. In fact, the cell structure suggests a Dicranella to me.

It looks like Dicranella heteromalla. I'll edit the earlier post so that the error isn't propagated into cyberspace.
