This project supports basic taxonomic studies on North American truffle fungi belonging in the genus Tuber (Fungi, Ascomycota, Pezizales). Truffles produce underground mushrooms that are widely sought as edible fungi by humans and foraging animals; as mycorrhizal fungi, truffles are also important components of healthy forest ecosystems. The primary aims of this project are: 1) To establish an authoritative phylogenetic classification system for Tuber species based on DNA evidence; 2) To define taxonomic groupings within several species complexes and widely distributed taxa; 3) To integrate and assign unidentified Tuber species from environmental samples (mycorrhiza and soil samples); 4) To establish a database for North American, European and Asian species with descriptions, digital images, and tools for web-based identification of unknown truffle species.This will be the first study to summarize our knowledge of global truffle diversity based on modern methods using DNA sequences combined with classic taxonomic approaches. This research project will also provide training in mycology and molecular ecology for several graduate and undergraduate students. Outreach activities include workshops and partnerships with amateur and commercial truffling groups, including development of online resources.

该项目支持块茎属（Fungi，Ascomycota，Pezizales）属于北美松露真菌的基本分类研究。 松露会产生地下蘑菇，这些蘑菇被人类和觅食动物广泛寻找为可食用的真菌。 作为菌根真菌，松露也是健康森林生态系统的重要组成部分。该项目的主要目的是：1）基于DNA证据建立块茎物种的权威系统发育分类系统； 2）在几个物种综合体中定义分类组并广泛分布的类群； 3）从环境样品（Mycorrhiza和土壤样品）中整合并分配未鉴定的块茎物种； 4）为北美，欧洲和亚洲物种建立一个数据库，具有描述，数字图像和基于网络的未知松露物种识别的工具。这将是首次研究我们基于现代方法的全球松露多样性知识，该研究使用DNA序列结合了经典分类方法。 该研究项目还将为几位研究生和本科生提供真菌学和分子生态学的培训。外展活动包括与业余和商业松露团体的研讨会和合作伙伴关系，包括开发在线资源。
