Nuclear ribosomal LSU

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.

Two new species found in Northwestern Pakistan in the mushroom genus Amanita are described and illustrated. Phylogenetic data derived from nuclear ribosomal ITS and LSU regions along with morphological characterizations indicate that these species are novel. Amanita cinis is a member of section Roanokenses, while A. olivovaginata is representative of the section Vaginatae. Amanita emodotrygon, recently described from the state of Uttarakhand, India, is new to Pakistan.

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.

A new species of the genus Barssia was identified from Turkey using both morphological and phylogenetic analysis of the ribosomal internal transcribed spacer region (ITS rDNA) and nuclear ribosomal large subunit (LSU rDNA) gene sequences.
