Hedwigia ciliata var leucophaea photographed by Des Callaghan from material he had collected from Dore Abbey, Herefordshire, where it had fallen down from stone tiles on the roof of the abbey. Subsequently Sam Bosanquet examined material he had collected from a similar habitat in Monmouthshire, which turned out to be the same plant, new to Wales. It may be that Hedwigia ciliata var leucophaea is more widespread than previously supposed as a member of the thermophilous community of bryophytes that is found on south-facing stone roof tiles.


Sematophyllum substrumulosum was first recorded from the British Isles in 1997 from Tresco in the Scilly Isles by David Holyoak. It then subsequently transpired that it had previously been collected at Kingley Vale NNR, where it was refound in quantity recently. This photograph was taken by Des Callaghan from material collected at this locality, and more can be found on the Bryophyte Portrait page.

Sphagnum fimbriatum with abundant sporophytes, both maturing and following explosive dehiscence when the lid is shot off by high pressure within the capsule. As in all Sphagna, the capsules are elevated above the level of the plant by a pseudopodium of gametophyte tissue, unlike most other mosses where this function is performed by a seta of sporophyte origin. Photographed at Wartle Moss, Aberdeenshire in July 2004 on the BBS Summer Meeting.

Racomitrium lanuginosum, a large acrocarp which can be dominant on wet heath in the north and west, photographed at Cape Wrath, West Sutherland, (VC 108), July 2005, by Martin Godfrey.

Entodon concinnus, a pleurocarp typically of calcareous grassland slopes, photographed in the machair of South Harris, Western Isles (v.-c. 110) August 2005

Riccia cavernosa on the horse-trampled exposed inundation zone at the NW side of Lough Rinn, H29. Photographed during the 2005 BBS Summer Meeting by David Rycroft.


Plagiochila atlantica is a Northern Atlantic species of open humid deciduous woodland, growing typically on sloping surfaces of rocks and the bases of tree trunks. It is found mainly in NW Scotland, with a few localities in the Lake District and Wales. There is also a record from Brittany. The photograph here was taken at Cwn Rheidol, Ceredigion, during the 2005 BBS Spring Meeting. It is seen here growing alongside Plagiochila spinulosa, and stems of the two plants are marked for comparison. It has now been synonomised with P.heterophylla (see

a: Conocephalum conicum
b: Conocephalum salebrosum

Conocephalum salebrosum is a taxon recently described by the late Professor J Szweykowski et al. as a cryptic species within the Conocephalum conicum complex. Originally detected through isozyme analysis, morphological characters are described in the recently published paper: J. Szweykowski, K.Buczkowska, I.J. Odrzykoski (2005) Conocephalum salebrosum (Marchantiopsida, Conocephalaceae) - a new Holarctic liverwort species. Plant Syst Evol 253, 1-4: 133 - 158 .

Bryum warneum in Britain is a rare coastal plant found growing in damp sand in dunes and amongst dune slacks. Photographed by Des Callaghan at Birkdale Green Beach, South Lancashire., April 2005.

Rhytiadelphus subpinnatus is a rare moss of open woodland with a few scattered records in western Britain. A new population was recently found by Sam Bosanquet by the Afon Tywi, Carmarthenshire, and photographed by Graham Motley.

Conocephalum japonicum (syn. C. supradecompositum) is the only other species of Conocephalum after C. conicum and it occurs in eastern Asia and Japan. It differs from C. conicum in producing abundant gemmiferous attenuate branches of the thallus. This picture also shows male cushions. It was taken by David Long on 12 October 2003 on a disturbed roadside bank in evergreen broadleaf forest at 2001m on the eastern slopes of the Gaoligong Shan mountains in SW Yunnan Province, China, on an expedition from the California Academy of Sciences and Kunming Institute of Botany, as part of the 'Biotic Survey of the Gaoligong Shan'.
