A survey was carried out in Gajni forest from June to August of 2017 and 2018 to document the diversity, distribution and morphological characterization of wild mushrooms. A total of 32 mushroom samples were collected and identified to 28 species belonging to 11 genera, under 8 families. Ganoderma sp. was found abundantly in the survey area 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 dominant genera were Ganoderma, Agaricus, Trametes, Volvariella and Amanita. The dominant family of collected wild mushrooms was Ganodermataceae followed by Polyporaceae, Agaricaceae, Amanitaceae, Rusullaceae, Pluteaceae, Marasmiaceae and  Strophariaceae. Among collected species, 5 species were found edible, 12 species had medicinal value and 11 species were inedible, poisonous or of unknown importance. The specimens were deposited to the Sher-e-Bangla Agricultural University Herbarium of Macro Fungi (SHMF). This is a report of wild mushrooms diversity and their distribution in the Gajni forest region of Bangladesh. This study was asserted that a wide range of mushroom plays an important role in the ecosystem of Gajni forest and might be useful in food and industry sector in future.

Survey on macro fungi was made in Gajni forest, Sherpur, Bangladesh which is located in between 24°18' and 25°18' north latitudes and in between 89°53' and 90°91' east longitudes. It is bounded by Meghalaya state of India on the north, Mymensingh and Jamalpur districts on the south with a wide range of ecosystem. The survey was conducted on July to December, 2018 to identify and preserve wood-rot causal macro fungi for future industrial utilization. Morphology of basidiocarp and characteristics of basidiospore were recorded. A total of 20 samples were collected and identified to 12 species belonging 7 families. Dominant species was Ganoderma species. The identified four species were from Ganodermataceae family and these were G. applanatum, G. lucidum, G. tropicum and G. lobetum. Other dominant genus was Russula. Other recorded genera were Hebeloma, Boletus, Phlebopus and Entoloma. Among them the highest frequency (85.72%) was recorded for G. applanatum and lowest frequency (7.14%) was recorded for Phlebopus marginatus. Similarly highest density (20.25%) was recorded for Agaricus sp. followed by G. lucidum (15.85%). The lowest density was (2.14%) was recorded for Phlebopus marginatus. Collected specimens were preserved in Sher-e-Bangla Agricultural University Herberium of Macro fungi (SHMF) for further study.
