When I first started this site, there were relatively few other general lichen image sites around (though Einar Timdal's and Ulrich Kirschbaum's sites were already invaluable and inspiring). Now there is a multiplicity of good, reliable sites and undoubtedly there are more top-quality sites that I have not listed. Ideally, there would be a search engine that indexed these sites, but if one exists, I don't know of it. At one time, Ed Uebel and Doug Greene produced an index to lichen images on the Internet, but their site is apparently long gone, and such an index would be a formidible task today.

It's a forlorn and desperate person who tries Google's image search, so there is little alternative to systematically going through the sites listed below for any given species. I give my own thanks to each and everyone who has produced these sites, as so often they have helped me solve my own mysteries.


British & Irish lichens - general  (see next section for image sites)

Images - Britain and Ireland

British Lichens (Mike Sutcliffe)
http://www.britishlichens.co.uk/

A site that first started, I understand, in the same way as my own, i.e. displaying images from courses run by Brian & Sandy Coppins - sometime after mine but with considerably more drive and diligence. Now a major resource and the best first site to try when searching for a good, reliably named image of a British lichen. [Changed name from http://www.uklichens.co.uk/, which still directs to the same pages.]

A huge and authoritative site that includes many photographs of British macrolichens, but with them arranged taxonomically amongst non-lichenised fungi and time-consuming to browse.
