Abstract

During a survey of diseases affecting pomegranate in the southeastern USA we identified a unique species of Diaporthales causing leaf spotting and fruit rot. Objectives of this study were to provide a morphological description of the putative new species, use DNA sequence data of three gene loci (LSU, ITS and rpb2) to accurately place the fungus within the Diaporthales, and to prove Koch's postulates. Morphological and phylogenetic comparisons confirmed the fungus to represent a new species and family, for which the names Dwiroopa punicae sp. nov. and Dwiroopaceae fam. nov. are proposed. This is the first report of a species of Dwiroopa being pathogenic to Punica granatum.
