Each name links to a page displaying 1 to 35 images. Most of the lichens in the photos are well-identified from voucher specimens, but I have included some whose identity is uncertain; almost all of these are also backed up by voucher specimens. Where something is identified only to a species "group", or is cfr. or sensu lato, I have placed it on the page with that species.
