Book Description
The systematics of species of Hypocrea with green ascospores and their Trichoderma anamorphs is presented. Multiple phenotypic characters were analysed, includingteleomorph and anamorph, as well as col-ony morphology and growth rates at varioustemperatures. In addition, phylogenetic analyses of two genes, the RNA polymerase II subunit (RPB2) and translation elongation factor 1-alpha (EF-1a), were performed. These analyses revealedthat species of Hypocrea with green ascosporesand Trichodermaanamorphs are derived from within Hypocrea but do not form a monophyletic group. Therefore, Creopus and Chromocrea, genera formerly segregated from Hypocrea only based on their coloured ascospores, are considered synonyms of Hy-pocrea. The present study showed that phenotypic characters alone are generally not helpful in understanding phylogenetic relationships in this group of organisms, because teleomorph characters are generally highly con-served and anamorph characters tend to be morphologically divergent within monophyletic lineages or clades. The species concept used here for Hypocrea/Trichoderma is based on a combination of phenotypic and geno-typic characteristics. In this study 40 species of Hypocrea/Trichoderma having green ascospores are described and illustrated. Dichotomous keys to the species are given. The following species are treated (names in bold are new species or new combinations): H. albocornea, H. atrogelatinosa, H. aureoviridis/T. aureoviride, H. can-dida/T. candidum, H. catoptron/T. catoptron, H. centristerilis, H. ceracea/T. ceraceum, H. ceramica/T. ce-ramicum, H. chlorospora/T. chlorosporum, H. chromosperma/T. chromospermum, H. cinnamomea/T. cin-namomeum, H. clusiae, H. cornea, H. costaricensis, H. crassa/T. crassum, H. cremea/T. cremeum, H. cu-neispora/T. cuneisporum, H. estonica/T. estonicum, H. gelatinosa/T. gelatinosum, H. gyrosa, H. lixii/T. har-zianum, H. macrospora, H. melanomagna/T. melanomagnum

Book Description
"Dedicated to those "passionate about fungi," this volume features species of important plant pathogens in tropical and subtropical regions. Crous (plant pathology, U. of Stellenbosch), president of the Southern African Society for Plant Pathology, introduces Cylindrocladium terminology, media and isolation techniques, pathogenicity, diseases, disease control, morphological methods and features, cultures, techniques for species characterization, phylogenetic analyses, and keys to various genera/species. The second section describes 54 species with cultural characteristics, disease symptoms, substrate, world distribution, cultures, and references."--pub. desc.

Book Description
Biological insecticides are competing more and more with traditional chemical pesticides. A successful application of natural pathogens requires a better understanding of both fungal and insect ecology and physiology. This Atlas provides a comprehensive overview of these fields and includes the taxonomy of those species of fungi which are proven pathogens. Biotechnological methods for the genetic modification of these natural pathogens resulting in further optimization and the advantages of biological control are discussed.

Book Description
Recently another book on insect physiology was published. It was restricted to a few focal points as are many of these new insect physiology books, but there was considerable depth in its specialized point of view. We were dis cussing the structure of this book and of insect physiology books, in general, when Prof. Remmert asked me " . . . and what about books on spider physio logy?" Silence. Then I started to explain "oh yes, there is a congress pro ceedings volume on this topic and there is a group with excellent publica tions on another topic . . . ", but I felt that this answer was weak. One can no longer buy the proceedings volume in a bookshop and to read a series of publications on a given topic one must search in a library for a dozen journals. Why is there not a single book on spider physiology comparable with the many books on insect physiology? Are spiders a scientific ivory tower, far from public interest and commercial importance? I do not think so, although spiders are one of the many "forgotten" animal groups which always grew in the shadow of the insects. There are research groups working on spider physiology, there are fascinating phenomena in this animal group and there are plenty of exciting results. Spiders may have been always underresearch ed, but research is progressing. In the last few years, new books have been published, e. g.
