Diversity and Ecology of Macrofungi in Rangamati of Chittagong Hill Tracts under Tropical Evergreen and Semi-Evergreen Forest of Bangladesh

Abstract

A detailed survey was made in Rangamati district of Chittagong hill tracts from July to October, 2016 to collect and record the morphological and ecological variability of macrofungi fruiting body. Collected macrofungi were washed with water and dried by electric air flow drier. Permanent glass slides were made from rehydrated basidiocarp for microscopic characterization. Morphology of basidiocarp and characteristics of basidiospore were recorded. Ecological features of the collected macrofungi and the collection sites such as location of collection, host, habit, frequency of occurrence, density and environmental temperature, soil type and soil moisture conditions were also recorded during collection time. A total of 66 samples of macrofungi were collected, recorded, photographed and preserved. Twenty species of macrofungi were identified under 17 genera and 15 families. The highest frequency of occurrence (44.44%) was recorded for Xylaria polymorpha. The highest density was found for Xylaria polymorpha also (55.56%) followed by Coprinus disseminatus (52.78%), Auricularia cornea (38.89%), Xylaria hypoxylon (27.78%) and Clavulina coralloides (16.67%). This is the first detail reports on macrofungi collected from Rangamati Hill Tracts forest of Bangladesh. Collected specimens were deposited to the SAU Herbarium of Macrofungi (SHMF).
