This volume of "Studies in Mycology" is a successor to a previous issue "Molecules, Morphology and Classification: Towards Monophyletic Genera in the Ascomycetes" (vol. 45, edited by Seifert, Gams, Crous & Samuels 2000). In this volume, the authors integrated new DNA phylogenetic information into an existing classification system, complicated by the need to accommodate fungal pleomorphy. The present volume continues the trend of applying multigene phylogenetics to generic and species concepts, extending the higher taxonomic level studies of the "Assembling the Fungal Tree of Life" project into a more finely resolved realm. Another controversy of contemporary ascomycete taxonomists, namely the issue of dual nomenclature, is also addressed in this issue, with authors of papers adopting five different interpretations of "One Fungus: One Name".
