Abstract:
Studies on the biodiversity, habitat and morphology of mushrooms are gaining
importance as many macro fungi are becoming extinct and facing threat of extinction
because of habitat destruction. Present study deals with the biodiversity, habitat and
morphology of mushroom grown in leaved, deciduous and mixed forest of Bangladesh.
More than 117 samples were collected from nine selected districts of Bangladesh viz.
Bari sal, Borguna, Patuakhali, Perojpur, Jhalokathi, Bandorban, Dhaka, Gazipur and
Tangail. More than 85% annual rainfall, mean daily temperature ranges between 29 to
31(Ie and relative humidity more than 80% is received during the monsoon period (June
to September). Soil pH ranges in between 6 to 6.5. Sandy clay, .clayand .clay loam soils
are suitable for growing of mushrooms. Maximum Mushrooms grown on natural humus
of the forest and maximum hard caped mushrooms such as Ganoderma grown on bark of
tree or dead plant as parasite or saprophytes. The size of fructification ranges from 3-4x23
to 20-25x8-10 em. The spore size was measured ranging between 5x3.S to 24x9 pm. In
total 20 different species were founded under 14 families viz. Amanitaceae ( Amanita
hemibapha, Amanita bisporigera, Amanita rubescens), Pyronemataceae (Aleuria
aurantia), Boletaceae (Boletus subvelutipes, Tylopilus badiceps, Retiboletus omatipesy;
Agaricaceae (Agaricus sp.), Tricholomataceae (Callistosporium sp.), Marasmiaceae
(Gymnopus sp.), Sarcosomataceae (Bulgaria inquinans), Russulaceae (Russula crustosa),
Roselliniaceae (Rosellinia sp.), Cortinariaceae (Cortinarius corrugatus), Mycenaceae
(Mycena epipterygia), Entolomataceae (Nolanea strictia). Ganodermataceae (Ganoderma
lucidum, Ganoderma apphannatum, Ganoderma tsuage) and Polyporaceae (Polyporus
sp.). The maximum frequency of occurrence was exhibited by Ganoderma tsuage
(33.33%) and the maximum density was recorded for Ganoderma tsuage (95%). This
informative study shows that the forest of Bangladesh is rich in mushroom diversity.
