REFEREES (Regional & Specialist) See web-site: http://www.britishlichensociety.org.uk/ 2 British Lichen Society Bulletin no. 110 Summer 2012 Welcome to the Summer 2012 Bulletin, fuller ever than before with articles, notes and reports from field meetings. Goings-on at the Natural History Museum feature in two articles, one focusing on James Stirton and his collections, the other a more general historical account of the Lichen Section from its inception until 1990. Caloplaca continues to get yet more complicated to the minds of some, but we should be grateful to Mark Powell and Jan Vondrák for uncovering the identities of collections from Buckinghamshire that may be Italian immigrants, and of species of the Caloplaca citrina aggregate. Two contributions from young lichenologists merit particular mention: one a report of a most impressive BLS-supported vacation project by a student in New Zealand, and the other by pupils from a London school who carried out an air pollution project (with a bit of help from Pat Wolseley and Holger Thüs) that impressed to such a degree that the project will feature in the Royal Society’s annual Summer Science Exhibition. It’s heartening to see such interest in lichens from the pre-arthritic generation. There’s also a bumper crop of reports from field meetings and workshops, emphasizing how active the BLS is when it comes to tramping around with a handlens and (legal) collecting knife (see the warning note). Meetings in Killarney (this one a rather delayed report!), Islay (avoiding the distilleries but not necessarily their products), Pembrokeshire (messing around constructively in streams, with some participants more immersed in the subject than others) and back to Derbyshire with a gritty meeting to complement the recent visit to limestone habitats. In the previous Bulletin, we learnt that lichens have the potential to control prion diseases (and see the article in Lichenologist 44(4): 523-531, 2012); now we find that the red orcein dyes extracted from Roccella tinctoria could hold the key to curing Alzheimer’s disease. See the article (in German) at http://www.gesundheitsforschung- bmbf.de/de/4455.php. There’s a way to go before the therapeutic potential of these lichen products can be fully understood, but the work underlines that lichens can do much more for us than decorate trees and rocks. And finally…. Members will be relieved to learn that the video presentation on Facebook entitled “The Living Dead – my Years in the BLS” refers to the US Government’s Bureau of Labour Statistics rather than the British Lichen Society.

A new project at the University of Nottingham will use the technique to investigate its complex morphology as a mechanism to improve competition for light resources in the high Arctic. 1 The James Stirton lichen collection at the Natural History Museum, London (BM) Scattered through the British and Foreign lichen herbaria at the BM and in the lichen herbarium in Glasgow (GLAM) are numerous small brown manila card packets (Figs 1A, 1B) neatly labelled by the Scottish lichenologist/bryologist James Stirton (1833-1917). Stirton’s handwriting is recognisable at once and is distinguished by its legibility (rare in the medical profession generally) and its graceful structure. At the BM, many more of these Stirton packets are in boxes as part of the great unincorporated lichen backlog that was stored initially on the tops of herbarium cabinets in the General Herbarium, and subsequently (c. 1990) transferred to the attic storeroom of the corner tower above the Palynology Suite. Fig. 1A: Stirton packet of Thelotrema hians Stirt. (GLAM) From 1973 until 1982, when I was preparing the first edition of Flora of New Zealand Lichens (Galloway 1985), I searched for many of Stirton’s New Zealand collections that were sent to him from Wellington by the Scottish draughtsman-botanist John Buchanan (1819-1898). Many of the BM collections were then still unincorporated, and an initial visit to Glasgow (GLAM) in 1978 disclosed the full extent of Buchanan’s New Zealand collections from which the BM specimens were derived as duplicates. Between 1873 and 1900 Stirton described 116 new lichens from Buchanan’s collections of over 180 different numbers, the largest number of new lichen names from New Zealand in the 19th century. Although Stirton’s New Zealand names are a significant tranche of his published output, he also made contributions to 2 knowledge of the lichen mycobiotas of many other regions and these will be discussed briefly below. James Stirton was born in Coupar Angus, Perthshire in 1833 (Lawley 2011). He graduated MD from Edinburgh University in 1858, his thesis entitled “On the Disorders of Digestion in Infancy” (Sally Pagan pers. comm.). He taught Mathematics at Merchiston School in Edinburgh from 1856-1858, and after graduation Stirton moved to Glasgow where he spent the rest of his professional life, established a large practice, was appointed Lecturer in Gynaecology in 1876 at the Glasgow Royal Infirmary, and in 1889 became Professor of Midwifery at St Mungo’s College (incorporated into the Medical Faculty of Glasgow University in 1947), a position he held for 15 years (Traill 1917; Boyd 1920). Besides pursuing a fulfilling medical teaching career, Stirton early developed a keen interest in mosses and lichens, making many and regular visits to the Scottish mountains, especially to Ben Lawers, to observe and collect. His parallel life in bryology/lichenology brought him fellowship and membership of several natural history and biological societies (The Linnean Society of London, the Philosophical Society of Glasgow, the Natural History Society of Glasgow, the Glasgow Society of Field Naturalists of which he was the first President, and the Botanical Society of Edinburgh), to whose journals he contributed many articles, and in whose activities he was an active member and frequently an office-bearer.

(GLAM) His publications in bryology and lichenology (see Trail 1917; Hawksworth & Seaward 1977) soon brought Stirton a wide correspondence with the leading bryologists and lichenologists of the day (e.g. James Crombie, William Leighton, 3 William Nylander, Edward Tuckerman, T.M. Fries, Jean Müller Argoviensis), and several collectors sent him lichens from many different parts of the world for identification, including: (1) New Zealand – his collectors being John Buchanan (Stirton 1873, 1874, 1875b, 1875c, 1877b, 1877c, 1878, 1881a, 1883a, 1883b, 1884, 1898a, 1900; Galloway 1985, 2007, 2012), Hugh Paton (Stirton 1881c, 1898a), Henry Travers (Stirton 1877b), Dr R. Pinkerton (Stirton 1883b) and T.W.N. Beckett (Stirton 1898a, 1900; Galloway 1998). (2) Australia - - his collectors being Hugh Paton, F.M. Bailey, Mrs Heywood McEwen, E. Spong. Mr Hartman, Rev. M. Anderson, Mrs McCann, Mr Kirton, Mr Falck, C. de Burgh, F. v. Mueller, C.J. Gwyther, Mr Sullivan and Mr Lucas (Stirton 1876a, 1878, 1880, 1881a, 1881c, 1883a, 1898a, 1898b, 1900; Rogers 1982). (3) South and West Africa – his collectors being Prof. P. MacOwan of Gill College, Dr John Shaw of Capetown, Mr J.H.
