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.
