A new species of Pseudocercospora causing leaf spot disease on Crotalaria assamica in India has been identified based on morphological and genetic analyses. The species shows similarities to allied species in the genus Pseudocercospora but is distinguished by its catenate and branched conidia. Phylogenetic analysis using LSU and ITS supports its classification as a new species in the Pseudocercospora genus.
A new species of Pseudocercospora is described causing leaf spot disease on Crotalaria assamica from India. The identity of isolate was based on asexual morphs, cultural characteristics and phylogenetic analyses of partial nuclear ribosomal 28S large subunit and complete internal transcribed spacer rDNA sequence data with high statistical support value. Morphologically this species has characters similar to allied species in genus Pseudocercospora but differs in having catenate and branched conidia. Phylogenetic analysis using LSU and ITS reveals it a new species of Pseudocercospora (Capnodiales, Mycosphaerellaceae).
