January 2016
Returning to work on this site after continued poor health and focus on other matters. Links to individual species accounts at the Fungi of Great Britain and Ireland website corrected and extended, after change in directory structure at that site.

I frequently add new page references to published useful descriptions and photographs. Last month, after a very long wait, I finally obtained a copy of Suomen Jäkäläopas by Stenroos et al. (2011), a truly splendid account of the Finnish macrolichens with superb photographs, and I duly added references to this work in my webpages. This month I have gone through the new, 2-volume account of the German lichens, Die Flechten Deutschlands, by Wirth, Hauck and Schultz (2013). This is effectively a revised and expanded version of Wirth's Die Flechten Baden-Württembergs, a much used 'standard', and nearly twice the price (in Britain), containing many of the same photographs, but also plenty of new ones of excellent quality. (See references.)

The Fungi of Great Britain and Ireland (includes lichens) is a significant resource that has been in development for two or three years by Paul Cannon at Kew. Recent agreements with other partners and societies mean this should continue into a major and authoritative reference source. In anticipation of this, and where there is content, I am beginning to add links from individual species pages.

Last month saw the very successful BLS meeting on the Isle of Muck (Inner Hebrides). Better weather (photographically), much better cameras and myself in better health than on Islay in 2011, and several rare species seen. I still have a huge backlog from Islay and Moray, and other non-BLS events and my own excursions and recording, but Muck "goodies" are being included in the latest updates.

This month has seen a major facelift for all of the species pages, a bit more professional, a bit less ageing hippie. October saw the publication of the new edition of 'Dobson', and also vol. 4 of the Nordic Lichen Flora, and references have been updated. Regrettably, photographs in both publications are poorly, sometimes very poorly, printed.

Other duties continue to affect my rate of posting. I still have a small residue from Kindrogan 2008, plenty still from Orielton 2009, my first BLS meetings (Norwich & Bristol 2010) and numerous other species photographed in between times.
Significant change this month has been the sad and sudden terminal illness of my treasured, large-format CRT monitor and, since the rest of the world has gone over to flat-screen monitors, I am reluctantly forced to do the same (higher definition but not matching the best CRT monitors in text or tonal quality and I hate the way the angle of view affects the display). This does force me to re-think screen definitions and even the bog-standard screen of my computer at work has a default setting of 1280×1024 (and cannot handle much else). All in all, the traditional 1024×768 is starting to look a little silly. I have decided that 1280×1024 is now to be the recommended definition for this site, but pages will still be tested at 1024×768. New images will often be larger than before, and where I think existing images can usefully be improved, the reposts will generally be at a larger size.
The page on Protoblastenia incrustans has been removed pro tem, as the existing photograph is of poor quality, unrepresentative and misleading. I hope to revisit the site and obtain something better.

The long awaited new edition of The lichens of Great Britain and Ireland was published during May and at last my own copy has arrived! Until now the names on this website have followed the BLS checklist of 2002, and pretty much matched Dobson (2005), but they have now been changed to match the new handbook. Individual pages under old names have (as warned) been removed from the site. 'Dobson' names remain traceable through the indices.

This month saw my attending the very enjoyable FSC fieldcourse at Orielton, Pembrokeshire, run by Pat Wolseley. With my having more than a year's backlog of new species and improved photographs, I shall predominantly be posting from the existing queue in the near future. However I shall no doubt fast-track some of the Pembrokeshire 'goodies'. Photographs of several Pembrokeshire Usnea species checked as part of a TLC (thin-layer chromatrography) demonstration are now already on-site.

New section! An index to lichenicolous fungi (i.e. fungi that grow on lichens) has been added. Many lichens are, themselves, lichenicolous, but these are treated with other lichens (as are certain non-lichenised fungi that are in the same genus as true lichens, e.g. Arthonia). By tradition, lichenicolous fungi are studied mainly by lichenologists and they are included in the British Lichen Society recording and mapping schemes.

RIP: the end of November saw the very sudden and very terminal demise of my computer. Fortunately, most of my important stuff was backed up, but obtaining a new computer that works with my various existing peripherals, finding and gettng all programs loaded, getting back on line, etc., etc., has taken time and caused a backlog of other tasks. Updates to this lichen site will be slow and irregular for the time being.

Thumbnail index structure revised (thumbnails are being progressively upgraded to slightly larger size and higher resolution, so fewer images per page will keep loading times reasonably fast – I hope!). Posting of Kindrogan 2003 photographs completed.
 

January–August 2008
Transfer from the currently existing site at http://www-biol.paisley.ac.uk/research/Asilverside/lichens/index.html is completed and I have added a number of additional species and upgraded (sometimes replaced) many of the photographs while doing so. I have added notes and references for each species and made other cosmetic changes. The old site will remain merely as an archive version until such time as the University of the West of Scotland life and environment teaching server goes offline.
 
Numerous species await addition. There is still a residue from the Kindrogan course of 2003; I now have plenty of new photographs from the course of 2008, and other photographs taken in between times and since. I shall add these in a probably haphazard and random fashion, as time allows, though I also have other (non-lichen) material to transfer from the old server and the slight inconvenience of having to work for a living. There are important genera for which I have uploaded no photographs at all as yet, better photographs of some of the existing species to add, more references to published descriptions and photographs to add, various cosmetic changes to be made, and at least one new section to be created. There will be periods of zero activity while other matters take priority, but keep tuned.
