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.

该项目支持对北美块菌属（真菌，子囊菌门，盘菌目）块菌真菌的基础分类学研究。 块菌产生的地下蘑菇被人类和觅食动物广泛用作食用菌;作为菌根真菌，块菌也是健康森林生态系统的重要组成部分。本项目的主要目的是：1）建立一个基于DNA证据的权威的系统发育分类系统; 2）在几个种复合体和广泛分布的类群中确定分类学分组; 3）整合和分配环境样品中未鉴定的块茎物种（菌根和土壤样品）; 4）建立北美、欧洲和亚洲物种的数据库，包括描述、数字图像，这将是第一个研究，以总结我们的知识，全球块菌多样性的基础上，现代方法使用DNA序列结合经典的分类方法。 该研究项目还将为几名研究生和本科生提供真菌学和分子生态学方面的培训。外联活动包括讲习班和与业余和商业松露团体的伙伴关系，包括开发在线资源。
