Shoots of an interesting looking
Cephalozia, which were scattered through several mounds of
Sphagnum subnitens growing in an area of mild base flushing @ SS49679051 proved to be
pleniceps under the microscope, based on leaf morphology (photos above). I’ll send a voucher to Sam as this is new for Glamorgan. Otherwise I only had limited time to check on a small area around the colony of
Palustriella falcata I noted earlier this year (I wanted to double check that I had correctly identified it following the recent nearby discovery of
Hamatocaulis – it was just
P. falcata - photos below). The spring line below where the Bracken ends (visible in aerial above) holds species such as
Anagallis tenella,
Campylium stellatum, Ctenidium molluscum, Fissidens adianthoides and
Philonotis calcarea. This is the first time I’ve looked at this faeture and I only had time for 10 minutes here, so well worth a revisit. Cefn Bryn continues to turn up interesting bryophytes and
Sphagnum platyphyllum is my new target now
H. vernicosus has been ticked off – there were some good pretenders today in the area with
P. falcata and
Scorpidium cossonii, but it was just odd-looking
denticulatum unfortunately. Checks of a couple of
Bryum samples from burnt areas of acid ground proved to be
bornholmense, which I would suggest is probably quite frequent at this site.

Excellent news Barry - and that's a super photo of the Cephalozia.
ReplyDeleteWell done on Cephalozia pleniceps - in its "fairly predictable locus" as reported by Graham and me in an early Field Bryology. Please don't send it to me though, as Nick Hodgetts is now Recorder for Liverworts.
ReplyDeleteGreat record Barry. So much there to explore.
ReplyDeleteI think nearest I came to finding it in Glam was at Cwm Cadlan - RCT, but Brecks vc. Nice one.
ReplyDeleteDo we need to take account of some of these things when planning future southern damselfly management?
ReplyDeleteWith species such as Hamatocaulis seemingly so localised, I'd say yes. It surprising how limited some of the basic flushes are.
