Lichen identification is challenging. Lichen literature is terse. Students of the higher plants have an enormous variety of books and web sites available to develop their knowledge. Lichenologists are a rare species themselves and good ones rarer still. Lichen biodiversity is vast and consequently they have little time to popularize their findings, or produce identification guides for amateurs.
The site is maintained by Paul Whelan. You can send me feedback (errors, suggestions and omissions) to paul[AT] lichens.ie.
I dedicate Lichens.ie to my good friend Frank Scallan, who died far too young in 2005.
Thank you to the Heritage Council of Ireland who provided some financial support for the initial step in this project back in 2008.
