Nordic Lichen Flora. Volume 2. Physciaceae.
Nordic countries are reknowned as having one of the richest and best known collections of lichen species in the world, with over 2000 species. Several Nordic lichenologists have initiated a project to produce a modern flora, the first since the C19, that will treat the whole lichen flora of the region. The second volume covers Physiaceae. This group contains many environmentally important indicator species, which now hopefully will be easier to recognize.
Descriptions of genera (plus keys) and species with notes on the thallus, chemistry, habitat and distribution. Appendices include distribution maps of species and colour photos of most species and varieties.
