I'll record it as B rubens but will hang onto the specimen.GMThttps://www.blogger.com/profile/08759152282751126808noreply@blogger.comtag:blogger.com,1999:blog-1572836115424987671.post-58715085963730078262015-05-26T20:07:43.502+01:002015-05-26T20:07:43.502+01:00Bryum rubens vs bornholmense is a difficult ID, co...Bryum rubens vs bornholmense is a difficult ID, covered about 10 years ago by Alan Crundwell in Journal of Bryology (a backissue I've now packed up for moving) following previous confusion. The bordered leaf and relatively broad cells suggest your Bryum is one or other of them, rather than B subapiculatum. From memory, the difference lies in mean width of cells on the tuber, prominence of tuber cell walls, and colour of tubers: the specimens of B bornholmense I have seen (including in Glamorgan) had strikingly honey-coloured tubers although I believe it can have red ones. I would err towards B rubens therefore.sambbryohttps://www.blogger.com/profile/16371859974181157877noreply@blogger.com
