A survey was conducted from June to August of 2017 to 2018 to record the biodiversity, distribution and morphological characterization of wild mushrooms. In total of 32 mushroom samples were collected and identified to 29 species belongs to 11 genera, under 9 families. Ganoderma sp was found abundantly in the survey areas among the other collected species and it exhibited the maximum frequency of occurrence (75%), whereas the maximum density (20.50%) was recorded for Agaricus bitorquis and the dominant host was shal tree (Shorea robusta). The dominants genera were Ganoderma, Agaricus, Trametes, Volvariella and Amanita. The dominant family was Ganodermataceae followed by Polyporaceae, Agaricaceae, Amanitaceae, Rusullaceae and Pluteaceae.
