Crofty update

male Fossombronia incurva

I spent about an hour on Christmas Eve exploring the abandoned Crofty building plot and recorded Cephaloziella integerrima on a total 12 of the post hole tumps, a few small patches on some of the adjacent banks, plus some reasonable patches on the abandoned footings themselves. The list of direct associates (i.e species within 10cm) below included Fossombronia incurva, this being just the second county record.

Sychryd scramble

On the 20th a climb up through the complex of boulders and falls along the Glamorgan side of the Sychryd boosted the totals for SN90D from 90 to 159 and SN90E from 41 to 106. Highlights from the limestone section included scattered colonies of Cololejeunea calcarea (photo 1 below), Neckera crispa (just one small tuft noted), Oxyrrhynchium schleicheri (one small colony), Rhynchostegiella teneriffae (sheets of it above water line, photo 2), Seligeria acutifolia (small amounts at 2 locations, photo 3), S. donniana (only 1 fruiting patch seen,, photo 4), Taxiphyllum wissgrillii (1 patch noted on a small embedded rock) & a little Dermatocarpon miniatum (photo 5).

A couple of logs in the higher acid section of the gorge supported species including Barbilophozia attenuata, Blepharostoma trichophyllum, Cephalozia catenulata (photo 1 below), Dicranodontium denudatum & Riccardia palmata, plus there were a couple of nice patches of Hymenophyllum tunbridgense half way up the valley side.

Of note for the wrong reason was a single 10cm x 10cm patch of Lophocolea semiteres established on the track as you walk down the north side of Dinas Rock.

Earlier in the day on the way up the Neath Valley, three lay-by stops along the A465 all showed that the putative Didymodon australasiae is a well established component of the verge dirt zone along this road. A little Ephemerum minutissimum was also collected and checked under microscope at one of the stops.

Lower Clydach River above Craig-cefn-parc

I never found anything remarkable during a two hour search along a 1km stretch of the river today, which lacked any cascades greater than what are visible in the above photo. There was a nice colony of Jungermannia pumila (above) on one of only a couple of small cliffs, but probably the most interesting species were Ephemerum minutissimum and Bryum sauteri in an area of disturbed M23a.

One curiosity was Phlebia radiata which was enveloping entire shoots of Hypnum cupressiforme creating an interesting form (note the sample on the right in the image below has been turned upside-down).
