Phylogeny And Taxonomy Of A Novel Species Of Pseudocercospora From India, Archana Singh, Paras Nath Singh, Gopal Nath, Nawal Kishore Dubey

Turkish Journal of Botany

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 >i>Pseudocercospora (Capnodiales, Mycosphaerellaceae).

Turkish Journal of Botany

Calopadia ruiliensis, found on living leaves in southwest China, is described as a new species, based on morphology and phylogenetic analysis. It is characterized by a foliicolous thallus with yellow greenish to creamy yellow color, rounded apothecia with nonpruinose to thinly pruinose disc, a dark olive-green hypothecium and black-brown subhymenium, and 1-spored asci producing muriform ascospores. Phylogenetic analysis of LSU sequence data shows that the new species clusters in the genus Calopadia with high bootstrap support. The new species is compared with closely related and similar species of Calopadia and a comprehensive description and micrographs are provided.
