PEET: Monographs of Two Key Genera and Family-Level Phylogeny (Fungi, Ascomycetes, Sordariales)

9521926 Huhndorf在一个雄心勃勃的项目中，研究一大群具有生态重要性的子囊菌真菌的系统学和系统发育，Sordariales的成员，菲尔德博物馆的Sabine Huhndorf博士组建了一个令人印象深刻的国内外合作者和学生团队。它们将解决目前真菌系统学面临的几个主要挑战，包括：(1)检查和测试用于子囊菌分类学的关键形态特征的变异，无论是环境还是遗传；(2)将多年来经常被赋予不同科学名称的真菌有机体的有性和无性阶段整合到系统发育和分类中；(3)通过对形态和分子(DNA)证据的严格系统发育分析来稳定属、科和目的名称；(4)评估中南美洲选定的热带地区的物种多样性；以及(5)对研究生和博士后进行真菌系统学传统和现代实践方面的培训。索德里亚真菌的两个大属--毛壳菌和毛壳菌--的分类专著，将是许多野外工作以及随后的实验室和博物馆研究的重点。研究和培训企业包括菲尔德博物馆的Greg Mueller博士和Francois Lutzoni博士以及加拿大、法国和瑞典的其他人，以及巴拿马和厄瓜多尔的同事。学生们还将参加在哥斯达黎加进行的实地考察和热带真菌学专业课程。通过支持真菌学“地鼠”服务器和其他服务，加强了标本收藏和其他计算机辅助活动的计算机化。

9521926 Huhndorf In an ambitious project to study the systematics and phylogeny of a large and ecologically important group of ascomycete fungi, members of the Sordariales, Dr. Sabine Huhndorf of the Field Museum has assembled an impressive team of collaborators and students, both nationally and internationally. They will address several of the major challenges facing fungal systematics today, including: (1) examining and testing variation, whether environmental or genetic, in key morphological characters used in ascomycete taxonomy; (2) integrating sexual and asexual stages of the fungal organism, which have often been given different scientific names over the years, into phylogenies and classification; (3) stabilizing genus, family, and order-level names through a rigorous phylogenetic analysis of morphological and molecular (DNA) evidence; (4) assessing species diversity in selected tropical regions of Central and South America; and (5) training students at graduate and postdoctoral levels in traditional and modern practices of fungal systematics. Taxonomic monographs of two large genera of sordarian fungi, Chaetosphaeria and Lasiosphaeria, will be the focus of much of the field work and subsequent laboratory and museum study. The research and training enterprises involve colleagues Drs. Greg Mueller and Francois Lutzoni at the Field Museum as well as others in Canada, France, and Sweden, and with colleagues in Panama and Ecuador. Students will also participate in ongoing field work in Costa Rica and in specialized courses in tropical mycology. Computerization of specimen collections and other computer-assisted activities are enhanced by the Field Museum's support for a mycology "gopher" server and other services.
