Nordic Lichen Flora. volume 4 Parmeliaceae

The fourth volume of the Nordic Lichen Flora deals with the largest macrolichen family, the Parmeliaceae, comprising about 2300 species and 80 genera, almost one sixth of all the known lichens. However, in the Nordic countries, only 152 species occur; these are distributed in 41 genera, here treated in separate chapters by a team of 13 specialists.
The corticolous lichens of the Parmeliaceae are often dominant in the landscape of northern arboreal forests, as are the members of the terricolous Cladoniaceae, the reindeer lichens, the family to be treated in the next volume of this series.
