Synopsis Meliolales of India by V.B. Hosagoudar is a comprehensive taxonomic monograph on Indian black mildews. It includes 375 species and infra-specific taxa which are presented in complete form for the first time. I hope it would serve as a useful manual to facilitate the identification of this highly specialised group of fungi in India. The line drawings are of specific value to the Mycologists and plant pathologists. The taxonomic position of several species and infra-specific taxa has been suitably placed after the detailed field, herbarium and laboratory studies by the author. In the present work, key to the genera is provided. Synoptic keys to the species are provided under their alphabetically arranged host families. All the species are arranged alphabetically under each genus. The genera are also arranged alphabetically. Line drawings are provided to the taxa examined and their numbers correspond to the taxa dealt in the text.
