摘要：The genus Inonotus is subdivided into genera Inocutis , Inonotus sens. str., Onnia and Pseudoinonotus . A key to these genera, based on studies of Indian material, is provided. A new species, Inonotus ryvardenii is proposed based on an unique set of characters like coarsely hispid pilear surface, absence of any setal organs and small, hyaline to pale yellowish spores. Six other species, Inocutis tamaricis , I. texanus , Inonotus juniperinus , I. obliquus , I. ochroporus and I. porrectus are reported new for India. All species are illustrated and described based on Indian material. A key to the Indian species for each genus is also provided
