LGBI3 draft accounts

The Lichens of Great Britain and Ireland (LGBI2) was published by the British Lichen Society in 2009, and has been the primary reference for identification of British lichens for nearly ten years now. Since then there have been substantial advances in our knowledge of their systematics and distribution. The British Lichen Society has therefore resolved to prepare a new edition of this work (given the acronym LGBI3). In late 2017 an Editorial Board was convened to oversee this task, composed of Paul Cannon, Brian Coppins, Alan Orange, Mark Powell, Janet Simkin and Rebecca Yahr. André Aptroot also joined the editorial board in November 2018. The Board met in November 2017 to plan a pilot phase of the project, to run until May 2018, and initial assessment suggests that the new edition will be ready for publication in around four years time.

The necessarily long period of preparation means that treatments of many genera will be completed as drafts well before the publication date. The BLS has therefore committed to publish genus accounts on its website as PDF documents (see table below), allowing their use as provisional treatments until publication of the entire volume. It should be stressed that these are interim accounts, which may well change in the light of further information and comment.

The new project is a major undertaking, and the Editorial Board hopes that as with the second edition, a broad range of lichenologists will contribute. This might include updating treatments in LGBI2 by the same authors, revisions of those chapters by others, or completely new accounts where major changes have taken place. A warm invitation is extended to anyone who may be interested in participating as authors or revisers in this project – in the first instance please contact Alan Orange (alanbiosurveys@outlook.com) who has kindly agreed to oversee the project administration.

In addition, we hope that anyone who uses the draft accounts will act as critical reviewers, and contact the authors and/or members of the Editorial Board to suggest alterations and corrections. We would like to make the new volume as practically useful as possible, and the more people that help in this way, the better it will be.


As part of this project we are also producing a more comprehensive and revised Glossary of terms, and all authors are encouraged to use these terms in a consistent manner. The draft Glossary and Notes to Authors can be downloaded below. Comments and suggestions will be very welcome and should be sent to Mark Powell.
