On a previous visit to my parents' house in Kendal (VC69) I took a sample of an odd-looking moss from a wooden fence which borders a park opposite their garden (50m asl). Some time later I checked it microscopically and was surprised to find it was a Racomitrium, but was unable to confirm which species and hadn't taken a photo of it in situ.
Last week I was back in Kendal and had another look - the moss was still there; in fact there were two patches growing a few metres apart. Judging by the sprawling growth I think it must be R. fasciculare. I can't find any references to this species growing on wood. Has anyone else seen it in similar situations?
