TL;DR: Strong boostrap support and significant posterior probabilities for the first time for the following monophyletic groups are produced, particularly for deep internodes of Basidiomycota, which have been difficult to resolve with confidence using nrDNA data alone.

TL;DR: It is concluded that concerted future collecting and comparison of specimens using multiple methodologies offer the only hope for understanding mushroom distributions, regardless of the geographic area of interest.

TL;DR: An update on efforts to catalog the basidiomycete taxa, particularly the mushroom-forming fungi, of Great Smoky Mountains National Park for the All Taxa Biodiversity Inventory is presented.
Abstract: We present an update on efforts to catalog the basidiomycete taxa, particularly the mushroom-forming fungi, of Great Smoky Mountains National Park (GSMNP) for the All Taxa Biodiversity Inventory. The goals of this project are to: 1) collect, identify, and voucher specimens with the help of visiting mycologists and volunteers; 2) extract DNA, amplify and sequence the nrITS region for barcoding, and deposit these sequences on GenBank; and 3) create species web pages for general public use. At present (April 2006), approximately 2000 specimens comprising about 770 species have been collected. As many as 45% are new Park records, and several may represent species new to science. DNA has been extracted from about 1000 specimens, and the nuclear ribosomal ITS region has been amplified and sequenced for about 500 of those. A surprising amount of genetic heterogeneity has been found, in part due to population migration patterns in response to glacial cycles. Studies with Artomyces pyxidatus support this ...
