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.
