Lower Clydach River above Pont Llechart

Another short visit into this cascade-free and almost cliff-free valley revealed no real surprises, with just a few tetrad additions. Species noted of general interest included Colura calyptrifolia (photo below), Fontinalis squamosa, Heterocladium heteropterum var. flaccidum, Schistidium rivulare, Solenostoma paroicum, and Trichostomum tenuirostre (photo below).


This Ash supported Radula complanata at a level of abundance I've not seen before; all of the green growth visible being this species.

Non-bryological interest was provided by a little bit of Sticta fuliginosa agg./sylvatica growing on a willow, a genus in which all species appear to be very rare in Glamorgan.

Margam sidings

Also known as 'Kenfig marshalling yards', this area is now a stunning brown-field slack full of  goodies.
The 'railway fen' always seems to provide something new each time I visit and a small patch of Pseudocalliergon lycopodioides at SS7913483514 provided the highlight of yesterday's visit. Whilst Calliergonella cuspidata was largely dominant, there's also a lot of Drepanocladus polygamus and D. aduncus in the flooded areas along with a wide range of interesting vascular plants and charophytes; those noted yesterday included Chara virgata, Equisetum variegatum (a), Pyrola rotundifolia subsp. maritima (lf), Cladium mariscus (o-lf) Juncus acutus (lf), J. subnodulosus (la), and Scirpoides holoschoenus. Not too shabby for an area of abandoned industrial land!

The drier gravelly sidings also provided a little interest with some nice carpets of Amblystegium serpens var. salinum growing alongside species such as Rhynchostegium megapolitanum, Bryoerythrophyllum recurvirostrum and rather oddly Neckera complanata on open flat ground. A 'golden road' of Schistidium crasspilum was a fine spectacle as the sun started to break through.

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 ...
