This volume provides a comprehensive world annotated checklist and bibliography of the ascomycete order Rhytismatales, together with associated organism and country indexes. It also includes approximately eighty line drawings of selected species and one hundred maps of selected individual taxa. The Rhytismatales is a group of particular importance in forestry, especially with respect to the Pinaceae. Members of this group have also been used in biological monitoring of air pollution. The book is therefore an important reference work for mycologists and forest tree pathologists.
