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.


  1. A very nice species list. Is any of that in NPT or is it RCT?

  2. Unfortunately from your point of view Charles, it is all within RCT.

  3. What a fabulous range of species...such a rich hunting ground for the bryologist.

  4. Hi Barry - unless I have overlooked some earlier record, I believe the Lophocolea would be new to VC 42.

  5. I'll send my specimen on to Sam in that case.
