British Lichen Society

At the instigation of Dougal Swinscow, the first meeting of the society was held at the British Museum on 1 February 1958; there were 24 attendees. Several positions were decided: Arthur Edward Wade was elected as the secretary, Peter Wilfred James as the editor and recorder, Joseph Peterken as the treasurer, David Smith the librarian, and Swinscow as curator and assistant editor.[3] Another founder was Ursula Katherine Duncan.[4]

A tenth-anniversary symposium, held jointly with the British Mycological Society, was held on 27 September 1968.[3] In 1983, the BLS held its silver jubilee celebrations to commemorate 25 years since its founding. A one-day lichenology symposium was held at the Natural History Museum, London, covering the topics ecophysiology, ecology, and lichenology in the Southern Hemisphere.[5]

Lichenologist Oliver Gilbert, former president of the BLS and editor of the organisation’s publications, wrote the book The Lichen Hunters in 2004; according to the blurb on the dust jacket, it is "part travelogue and part social history of the British Lichen Society from ... 1958 to the present".[6]

A series of events are held each year led by members of the society. These include field and indoor meetings and training events. In conjunction and with support from the BLS, the Field Studies Council started giving field courses on lichens in 1958, initially led by Arthur Wade and held at the Malham Tarn Field Studies Centre. These courses helped increase awareness and interest in field lichenology in the British Isles. In 1964, the BLS undertook the Society Distribution Maps Scheme, a major citizen science project led by Mark Seaward. This effort ultimately resulted in the 1970 publication Introduction to British Lichens, after which it became possible to reliably identify most lichens found in the UK. Distribution maps of species were distributed in the October 1973 issue of The Lichenologist, and this data was incorporated into other biogeographical lichen research, including studies on the effects of pollution on local lichen populations.[3] The society also makes grants to support projects that study lichens. It works with other organisations.

The Society publishes a scientific journal, The Lichenologist, that focusses on the taxonomy of lichens as well as their ecology and physiology.[7] It was founded by Dougal Swinscow[8] and edited by Peter Wilfred James from 1958 until 1977[9] and by Peter Crittenden from 2000 to 2016.[10] There is also a twice-yearly members' bulletin, BLS Bulletin. This was edited from 1980 until 1989 (except not 1987) by Oliver Gilbert.[11] The society also maintains a database of the lichens in England and Wales, a library based at the National Botanic Garden of Wales, and a herbarium.

The BLS elects a new president every two years:[12]
