Plagiomnium cuspidatum with a few scraps of Lophozia excisa
I nipped down to Penclawdd to take Alfie for his constitutional walk today and spent 40 minutes on part of the ridge mentioned below. I was very pleased to relocate Sam's Plagiomnium cuspidatum, although P. affine/undulatum? [see below] was more frequent and I also found a few scraps of Lophozia excisa. In the process of producing a more complete list for the site I was struck by the Bryum below, which looks very kunzei-like to me. Whilst calcifuge species were more prominent, there were scattered patches of calcicoles; associates in the immediate vicinity of the Bryum included P. affine, B. capillare, Hypnum cupressiforme var. lacunosum, H. jutlandicum, Ceratodon purpureus & Barbula convoluta. Under the microscope the leaf margins are very weakly bordered with a few tiny, but sharply pointed teeth distally. the margins are weakly recurved towards the leaf base which is pigmented red. The single unripe sporophyte may be a bit of a negative as I'm not sure if fruiting is known in Britain? As always any comments are welcome.
Bryum caespiticium and spot the Lophozia excisa!
Re: Plagiomniun aff/und - I often get muddled by these two as stunted undulatum looks very similar to affine to me - what is the best way to separate them in the field?
