Basidium and Basidiocarp : Evolution

The intent of this publication is to bring together reviews and discussions from several disciplines, all treating the basidium and basidiocarp of the Basidiomy- cotina (= basidiomycetes), a subdivision of the true or higher fungi. Because the workers who study the species of this group employ such a variety of techniques and publish in such diverse journals, we believe that bringing together these efforts in one publication will facilitate a synopsis of recent studies of several divergent disciplines. Correlation of such information may not only aid in the reevaluation of broad taxonomic and biological concepts but also provide a key to the specialists in the rethinking of the data available within the confines of the more restricted disciplines. We have attempted to cover the major areas of studies of species of the Basidiomycotina within the past decade or so with the exception of genetics and compatibility, which have recently been reviewed in several other works. A problem we have not been able to solve satisfactorily is the one of vocabulary. Each discipline tends to develop its own language as it becomes increasingly specialized, with time becoming unintelligible to the majority. We have tried to alleviate this problem of terms but can not claim to have been completely successful. We are indebted to a great many people, but especially to the contributors. They have been most patient and cooperative throughout.
