Racomitrium sudeticum, Mynydd Ton (RCT)
Growing on a sandstone outcrop with R. heterostichum, R. aquaticum and Andrea rothii ssp. falcata on the exposed trail on Mynydd Ton near the boundary between RCT and Bridgend counties (SS9493).
The narrow leaves with short hairpoints and the dull green, compact cushions look quite different from the more lax, hoary (greyish) colonies of R. heterostichum (which have longer hairpoints).
Short hairpoint of R. sudeticum
Lower part of leaf showing elongated, non-papillose, sinuous cells.
My guess is that R. sudeticum is scattered about on the higher, exposed sandstone outcrops of RCT and Bridgend, so we can expect more records in VC41.
