A new species Pseudocercospora solanicola is discovered causing severe leaf spot disease on Solanum nigrum from Sonebhadra. Species is described and illustrated based on morphology, molecular sequence analysis and phylogeny of the large subunit (LSU) and internal transcribed spacer region of the nuclear ribosomal RNA (rRNA) gene. Morphologically, new species has similarity with allied species in Pseudocercospora but differs in having black circular, velvety leaf spot and size of stromata, conidia and conidiophores. A key to Pseudocercospora species on Solanum has been provided. |
