Nordic Lichen Flora

The lichen flora of the Nordic countries, containing about 2000 species, is regarded as one of the best known in the world.Lichenological research of the region has been continuous since the time of Erik Acharius (1757–1819), the "father of lichenology", but it is a sad fact that there is no modern treatment of the region’s impressive lichen flora, the last attempt in the 1870s being that of Th. M. Fries, his major work, Lichenographia scandinavica, unfortunately remained unfinished.

A number of specialist lichenologists have united forces to produce this much needed Nordic Lichen Flora.
