The NATO Advanced Study Institute on Numerical Taxonomy took place on the 4th - 16th of July, 1982, at the Kur- und Kongresshotel Residenz in Bad Windsheim, Federal Republic of Germany. This volume is the proceedings of that meeting, and contains papers by over two-thirds of the participants in the Institute. Numerical taxonomy has been attracting increased attention from systematists and evolutionary biologists. It is an area which has been marked by debate and conflict, sometimes bitter. Happily, this meeting took place in an atmosphere of "GemUtlichkeit", though scarcely of unanimity. I believe that these papers will show that there is an increased understanding by each taxonomic school of each others' positions. This augurs a period in which the debates become more concrete and specific. Let us hope that they take place in a scientific atmosphere which has occasionally been lacking in the past. Since the order of presentation of papers in the meeting was affected by time constraints, I have taken the liberty of rearranging them into a more coherent subject ordering. The first group of papers, taken from the opening and closing days of the meeting, debate philosophies of classification. The next two sections have papers on congruence, clustering and ordination. A notable concern of these participants is the comparison and testing of classifications. This has been missing from many previous discussions of numerical classification.

Chaetomium genus was established by Gustav Kunze in 1817. According to Index Fungorum Partnership, there are 273 Chaetomium species accepted till now. Members of the genus Chaetomium are capable of colonizing various substrates and are well-known for their ability to degrade cellulose and to produce a variety of bioactive metabolites. More than 200 compounds have been reported from this genus. A huge number of new and bioactive secondary metabolites associated with unique and diverse structural types, such as chaetoglobosins, epipolythiodioxopiperazines, azaphilones, depsidones, xanthones, anthraquinones, chromones, and steroids, have been isolated and identified. Many of the compounds have been reported to possess significant biological activities, such as antitumor, antimalarial, cytotoxic, enzyme inhibitory, antimicrobial, phytotoxic, antirheumatoid and other activities. Chaetomium taxa are frequently reported to be cellulase and ligninase producers with the ability to degrade cellulosic and woody materials. This is the first, comprehensive volume covering Chaetomium genus in detail. It includes the latest research, methods, and applications, and was written by scholars working directly in the field. The book also contains informative illustrations and is fully referenced for further reading.

Taxonomy is universally neede discipline and great importance in attempting summation and organization, in order to provide a workable systems for classification. Therefore construction of taxonomic group of various Chaetomium species, and naming them, identification; exhibiting in sociological and behavioral characteristics such as geographical distributions of the constituent species, habitat spceificity, species diversity in the community and function in the ecosystem. In Malaysia, the prevailing conditions and climate should probably enhance rapid microbial deterioration but studies on the role played by Chaetomium in tropical soils is largely lacking.

Excerpt from A Monograph of the Genera Chaetomium and Ascotricha As a result of a thorough review of the literature one hundred and fourteen species names and fourteen variety names have been found which'have been applied to forms supposedly Chae tomia. In the present revision a considerable number of changes have been made., Names which were first used in connection with good species have been retained, while many others have been listed as synonyms thereto. For reasons given elsewhere, a considerable number have been excluded, and the writer feels that the use of such names should be discontinued. Certain new names representing new forms heretofore unrecognized have been added to the list of known species. Nevertheless according to the best judgment of'the writer, the genus should include not more than twenty-eight species.

The first section reviews trends of bean production and constraints in Latin America and Africa. The second section covers fungal diseases. The third section, bacterial diseases. The fourth section, viral and mycoplasma diseases. The fifth section, insect pests. The last section, other bean production constraints, that is, nutritional disorders, nematodes, seed pathology, and additional problems.
