The Clavariaceae is a poorly studied family of mushroom-forming fungi and the earliest evolutionary branch in the order Agaricales, the most diverse group of mushroom-forming fungi in the Agaricomycotina. The family is characterized by a high diversity of morphological and ecological features, including roles as decomposers and plant root symbionts. A robust phylogeny coupled with evolutionary analyses should yield insights into patterns that have led to its high diversity. The products of this research will include a molecular-based phylogeny, with which ecological and trait evolution analyses will be performed. Additionally, identification and description of novel species and a taxonomic revision of the family are planned. The research will also contribute to the first modern floristic treatment of the family in the United States.Results of this research will be presented at professional and amateur scientific meetings. A molecular reference dataset of known species of Clavariaceae will be produced that will aid identification of DNA sequences obtained from soil and other environmental samples. The proposed collaborative effort involves researchers in Europe and Australia and contributions from domestic and international herbaria and amateur naturalists. Several undergraduates will be trained in aspects of molecular biology and mentored in evolutionary biology.

棒孢菌科是伞菌目中最早进化的分支，也是伞菌亚门中最具多样性的伞菌类群。该科的特点是高度多样性的形态和生态特征，包括作为分解者和植物根共生体的作用。一个强大的生物学加上进化分析应该产生的模式，导致其高度多样性的见解。这项研究的产品将包括一个基于分子的遗传学，生态和性状进化分析将进行。此外，还计划鉴定和描述新物种，并对该科进行分类学修订。这项研究也将有助于美国第一个现代植物区系的处理。这项研究的结果将在专业和业余科学会议上发表。将产生一个已知棒孢科物种的分子参考数据集，这将有助于鉴定从土壤和其他环境样品中获得的DNA序列。拟议的合作努力涉及欧洲和澳大利亚的研究人员以及国内和国际植物标本馆和业余博物学家的贡献。一些本科生将接受分子生物学方面的培训，并接受进化生物学方面的指导。
