Andaman Islands are rich in plant diversity. During 2015-2019 we explored these Islands for Ascomycetous fungi. Among the various groups of fungi that we have encountered, we recorded a greater number of new species and new records belonging to the order Hysteriales comparatively, in South Andaman. These comprise 10 species distributed in five diff...

The rust genus Skierka belonging to the phylum Basidiomycota was described in 1900 by Raciborski with Skierka canarii as the type species. The published literature on this rust genus reveals its ambiguity in taxonomic placement. It was challenging to taxonomically delineate and precisely identify each species within this genus due to the species sh...

Uromyces is the second-largest plant pathogenic rust genus, is responsible for numerous diseases, and has major effects on both agricultural and non-agricultural plants. The genus is generally characterized by its unicellular teliospores that help to characterize it and distinguish it from another important rust genus, Puccinia. In this study, a gl...
