The Flora Agaricina Neerlandica seriesprovides original descriptions and illustrations of agarics and boletes (Agaricales sensu lato, Boletales, and Russulales) occurring in the Netherlands, together with chorological and ecological data. It also provides the correct names of individual taxa, concise synonymies, and keys. This volume covers the Families Coprinaceae and Bolbitiaceae and the genera Coprinus, Bolbitius, conocybe, Pholiotina, and Agrocybe. Since the publication of Volume 1, new understanding of the relationships between orders, families, and genera has emerged. These new findings are discussed and incorporated in this volume.
