If you would like to contribute to future years' programmes, please get in touch with Lucia Ruffino. Lucia has also put together some guidelines for meeting organisers, which you may wish to look at to get some idea of what is involved.



  • ** New ** The 2021 Spring Meeting is scheduled for 9-16 April 2021.

  • Burkhard Biel's Aegean Bryophyte Atlas has been updated with the latest distribution data (30th April 2020).

  • For those of you who were looking forward to coming to the summer meeting on Jura this year, some cheery news: we are hoping to reschedule the event for June 2021, (Saturday the 19th to Saturday the 26th), and the village hall has been booked for evening microscope work again for that week, (pending the easing of travel restrictions etc of course).

  • Sean Edwards has produced a 5th Edition of his book English Names for British Bryophytes. This is now available to view and download from the Downloads page. There is also a simple spreadsheet containing just the Latin names and their equivalent English name(s).

  • Phil Stanley’s latest version of the BBS Cumulative Index, version 16.1 has been uploaded (dated 17 February 2020) and is avaiable at
    It now includes citations from Journal of Bryology volume 41, Part 4 (2019) and up to Field Bryology 122 (2019) and also a list of all the references quoted in papers (Allrefs) published in Journal of Bryology and Field Bryology.

  • Updated Census Catalogue now available The Census Catalogue has now been updated to include all data up to the end of 2018. It is available from the Resources >> Downloads page as a Word document and in spreadsheet format.

  • T&F Journal alerts Those of you who use the Taylor & Francis website to access Journal of Bryology online may be interested in a new option to register for email alerts whenever a new article is published online. You will need to create an online account (free), then click on the New content alerts button on the main JoB page and follow the instructions. If you have any problems with this, please contact T&F, not the BBS.


Assessment of the conservation status of Vaucheria species in England

Request for specimens

The conservation of freshwater algae (apart from charophytes and a few particular species or genera) has been neglected throughout much of the world. In recent years, some work has been done to try to rectify this in England through projects funded by the Natural England Species Recovery Programme, looking at the conservation of Gongrosira scourfieldii (John et al. 2019) and compiling a Red List of species in the genera Nostoc and Rivularia (Lansdown and Pentecost 2019). The former was successful, enabling discovery of new, stable populations but the latter mainly highlighted the lack of information on these two genera.

In an attempt to find ways to inform conservation of freshwater algae in England, a different approach is being tested, looking at the distribution and conservation status of species in the genus Vaucheria Candolle, 1801.  

Bryologists often see algae mixed in with our target species. Now is your chance to find out a little more about them and contribute to scientific understanding of terrestrial forms of freshwater algae.

Richard Lansdown is leading this project and has asked for specimens to be sent directly to him. Full details are given in the attached flyer. Any questions should also be directed to Richard by email at



New Atlas of British and Irish Bryophytes

A reminder to all bryophyte lovers that the Atlas of British and Irish Bryophytes is available for sale from this link.

This flagship publication of the BBS not only holds the most up-to-date set of distribution maps for all British and Irish bryophytes but also a wealth of information about each species’ ecology, altitudinal range, associated species and world-wide distribution.

A stupendous achievement by the authors as well as a tribute to the work of the BBS: it is difficult to know why anyone would not be anxious to secure a copy.

BBS Field Guide to the Mosses and Liverworts of Britain and Ireland

This book, produced by the BBS, is the only up-to-date, user-friendly guide to identifying British and Irish bryophytes in the field.  It contains hundreds of colour photographs and black and white drawings showing what species look like, together with notes on how to identify and distinguish similar species, and habitat notes and distribution maps showing where they occur.

An essential field companion for any serious bryologist.

Future Meetings

Would you like bryologists from all over Britain and Ireland to come and help you record your county or local area?

If the answer is yes, then you could host a BBS Spring or summer Meeting! Spring and Summer meetings are usually 5 -7 days long and all you need to do is find sites that need recording. A bunch of friendly bryologists will then come and record in the chosen locations and you can watch the record cards coming in... Meetings are also a great opportunity for beginners to learn from expert bryologists in the field.

If you think you could host a Spring or Summer meeting in 2019 or 2020, please get in touch with Lucia Ruffino at or on Twitter.
