Distribution maps for all the British species of lichens and lichenicolous fungi are available here. These are more up to date and accurate than those on the NBN Atlas. Please note that these maps can only show the known locations for each species. The absence of a dot does not necessarily mean that the species is not there, only that we don't have a record for it - yet. "Absence of data is not data of absence".
We are gradually building these pages up into species accounts, with text and photos to aid identification. More technical accounts for many species can be found on the Fungi of Great Britain and Ireland website and in the Lichens of Great Britain and Ireland (LGBI3) PDFs.
Taxonomy changes: If the search here does not work, please look for it in the taxon dictionary and click through from there. Please note that when taxon names are changed there is always a delay before they can be updated in the database and maps, so you may have to use the previous name to link to the Interactive Map.
