Heritage CouncilLichen 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.

I dedicate to my good friend Frank Scallan, who died far too young in 2005.
