DIVERSITY, DISTRIBUTION AND MORPHOLOGICAL CHARACTERIZATION OF WILD MACRO FUNGI FROM GAJNI FOREST

Abstract

A detailed survey on macro fungi was made in Gajni forest, Sherpur, Mymensingh, 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 collect and record the biodiversity, distribution and morphology of wild Macro fungi. Collected macro fungi were washed with water and dried by drier. Permanent glass slides were also made from rehydrated basidiocarp for microscopic characterization. Morphology of basidiocarp and characteristics of basidiospore were recorded. Ecological features of those collected wild mushrooms and the collection sites such as location of collection, habit,host. frequency of its presence, density and environmental temperature, soil type and soil moisture conditions were also recorded during collection time. In this survey a total of 20 samples were collected and identified to fourteen species belonging eight families. Dominant species was Ganoderma species.The identified four species were from Ganodermataceae family and these are Ganoderma applanatum, Ganoderma lucidum, Ganoderma tropicum and Ganoderma lobetum. Another dominant species were from Agaricaceae family and these were Agaricus bitroquis, Macrolepiota procera and Agaricus spp. Other recored species were Chanterella cibarius, Termitomyces sp, Boletus edulis, Entoloma sp, Phlebopus marginatus, Russula crustosa and Russule nobilis. Among them the highest frequency (85.75%) was recorded for Ganoderma applanatum and lowest frequency (7.14%) was recorded for Phlebopus marginatus. Similarly highest density (20.25%) was recorded for Agaricus bitroquis and followed by (15.85%) for Ganoderma lucidum. The lowest density was (2.14%) for Phlebopus marginatus. Collected macro fungi specimens were deposited to Sher-e-Bangla Agricultural University Herberium of Macro fungi (SHMF). Findings of the present survey emphasized the importance and diversity of macrofungi in the Gajni forest, Sherpur, Bangladesh.
