Odd Orthotrichum

The above tuft was noted in a young Ash plantation near Pont-Henri, where many of the trees looked to be in very poor health. Essentially it is O. pulchellum but with capsules on very short setae, resulting in them being hidden among the shoots. I couldn't make it anything rarer unfortunately, but would be interested to know if this appearance is unusual?
The trees may be sickly, but the extra light seems to have allowed the bryophytes to do well ...
... with abundant Frullania dilatata, 3 Metzgeria spp. & Radula complanata

Commonest bryophyte species

Julita Klusa has just put a link to her list of Latvia's top 20 commonest bryophytes on Twitter.  It is fascinatingly different to the top 20 in south Wales!

Rank Pembrokeshire (SW Wales) Latvia UK notes
1 Kindbergia praelonga Hypnum cupressiforme Abundant (No. 2 in Pembrokeshire)
2 Hypnum cupressiforme Leucodon sciuroides Uncommon and very local
3 Brachythecium rutabulum Hylocomium splendens Locally abundant but habitat specific
4 Frullania dilatata Plagiomnium undulatum Locally abundant but habitat specific
5 Metzgeria furcata Pleurozium schreberi Locally abundant but habitat specific
6 Lophocolea bidentata Rhytidiadelphus triquetrus Locally abundant but habitat specific
7 Isothecium myosuroides Dicranum scoparium Locally abundant but habitat specific
8 Bryum dichotomum Climacium dendroides Uncommon and local
9 Mnium hornum Orthotrichum speciosum Rare and eastern, not in Wales
10 Tortula muralis Radula complanata Increasing and locally abundant
11 Bryum capillare Atrichum undulatum Abundant (No. 12 in Pembrokeshire)
12 Atrichum undulatum Nowellia curvifolia Locally abundant but habitat specific
13 Ulota phyllantha Rhytidiadelphus squarrosus Locally abundant but habitat specific
14 Dicranella heteromalla Eurhynchium angustirete Not British
15 Bryum argenteum Homalia trichomanoides Locally abundant but habitat specific
16 Calliergonella cuspidata Ptilium crista-castrensis Uncommon and north-eastern
17 Fissidens bryoides Plagiochila asplenioides Locally abundant but habitat specific
18 Thuidium tamariscinum Syntrichia ruralis Locally abundant but habitat specific
19 Didymodon insulanus Neckera pennata Extinct in Britain, one historic record
20 Ulota bruchii Plagiomnium cuspidatum Uncommon and very local

This has got me thinking again what a pity it is that the South Wales Bryophyte Blog is only visible to 'members' and I wonder whether we could make it more visible but with commenting and blogging limited to 'members'.
