In the present study, White rot fungi Trametes sp., Ganoderma sp. and Poria sp. were collected from decayed wood of Tamirandus indica, Eucalyptus grandis and Tectonia grandis respectively from the western ghats region of Tamilnadu and Karnataka in India. The collected fungi were isolated and identified based on the morphological characters from the key provided previously. The collected fungi were examined for biobleaching and delignification of hard wood kraft pulp (HWKP). In biobleaching and delignification of HWKP, all the three fungi reduced the kappa number and increased the brightness of the pulp after 10 days of incubation. The maximum reduction in kappa number (12.76%) and brightness (44.87%) were determined in Poria sp.
