abstract = {The species of rust fungi (Pucciniales) inciting disease on switchgrass (Panicum virgatum) grown in bioenergy feedstock systems across the north-central and eastern United States remain unclear. In the present study, the species number and phylogenetic relationships of rust species affecting switchgrass were examined in 2011?2013 at two sites in New York State as well as selected sites in Alabama, Iowa, Nebraska, Pennsylvania, South Dakota, and West Virginia using ribosomal RNA gene data (partial internal transcribed spacer [ITS] 1, complete 5.8 subunit [S] and ITS2, and partial 28S). Uredinial group and teliospore morphology were also utilized to delimit taxa in collection years 2012 and 2013. Maximum likelihood, maximum parsimony, and Bayesian analyses demonstrated two monophyletic clades. Clade I consisted of Puccinia emaculata and included the majority of single-sorus isolates across sites, whereas, Clade II included multiple isolates from Iowa, Nebraska, and South Dakota. Single-telial isolates for Clade I possessed only two-celled teliospores while Clade II isolates possessed only one-celled teliospores, and hence, were readily diagnosed morphologically to P. emaculata and Uromyces graminicola, respectively. No U. graminicola sequences exist in GenBank to compare with our Clade II isolates; however, based on teliospore morphology, the identity of Clade II taxa is U. graminicola.}
