PEET: Monographic Research in Agaricales and Aphyllophorales(Basidiomycotina, Fungi)

小行星9521526 在全世界数以千计的真菌物种中，具有通常明显的子实体的较大的担子菌，例如蘑菇和马勃菌，是相对众所周知的。 尽管如此，它们的分类仍然依赖于地理上受限制的处理方法（按地区或政治实体），经常导致科学名称的重复，并且往往依赖于受环境影响的形态特征，因此证明是不稳定的。 田纳西大学的罗纳德彼得森博士组建了一个由同事和贡献者组成的团队，从世界范围内的角度研究了伞菌目和无褶菌目的几组真菌，并采用了几条证据进行分类解析和系统发育分析。 这些是包括传统的形态特征（加拿大的Scott Redhead博士和瑞士的Egon Horak博士等同事的贡献）;蛋白质电泳和DNA测序中的新分子工具（与同事卡伦休斯博士）;实验室培养和交配试验，以评估密切相关的物种之间的相容性反应;所有这些都将通过利用现有的植物标本馆收藏和从各个地区广泛的实地收集收集的新收藏来实现。 主要重点将给予属clavicorona，金针菇，香菇的专题治疗。 研究生和博士后的培训需要课程和研讨会，广泛的实验室和博物馆工作，以及在美国和通常在国外的实地收集。 专题研究工作的许多方面，包括标本数据库、形态学和分子学评价以及鉴定关键字的建立，都将实现计算机化，从而通过大学的万维网服务器加强成果的传播。

9521526 Petersen Among the thousands of species of fungi worldwide, the larger basidiomycetes with often conspicuous fruiting bodies, the mushrooms and puffballs for example, are comparatively well known. Still, their classification rests upon geographically constrained treatments (by region or by political entity), frequently with consequent duplication of scientific names, and with reliance often placed upon morphological features that are subject to environmental modification and hence prove unstable. Dr. Ronald Petersen at the University of Tennessee has assembled a team of colleagues and contributors to study several groups of fungi in the orders Agaricales and Aphyllophorales from a worldwide perspective, and by employing several lines of evidence for taxonomic resolution and phylogenetic analysis. These are to include traditional morphological characters (with contributions from such colleagues as Dr. Scott Redhead in Canada and Dr. Egon Horak in Switzerland); new molecular tools in protein electrophoresis and DNA sequencing (with colleague Dr. Karen Hughes); laboratory culturing and mating trials, to assess compatibility reactions among closely related species; and all these to be pursued through the use of existing herbarium collections and new collections assembled from extensive field collecting in various regions. Primary emphasis will be given to monographic treatments of the genera Clavicorona, Flammulina, and Lentinellus. Training of graduate and postdoctoral students entails courses and seminars, extensive laboratory and museum work, and field collecting in the U.S. and usually abroad as well. Computerization of many aspects of the monographic endeavor, including specimen databasing, morphological and molecular evaluations, and construction of identification keys, will enhance the dissemination of results through the University's World Wide Web server.
