MORPHOLOGICAL CHARACTERIZATION OF MUSHROOMS ASSOCIATED WITH FOREST TREE OF NATIONAL BOTANICAL GARDEN, DHAKA

Abstract

This investigation was conducted in National Botanical Garden, Dhaka located at

24°00 N (Latitude), 90°00′ E (Longitude) to document the morphology, diversity and distribution of macro fungi during the rainy seasons of July to October, 2015. A total of 23 mushroom samples were collected and identified to 17 species under 10 genera and 10 families. The predominant genera were Ganoderma sp., Lepiota sp., Daedeleopsis sp., Russula sp., Psythyrella sp., Lycoperdon sp., Crepidotus sp., Psilocybe sp, Flammulina sp. and Cantharellus sp. The survey revealed that five species are edible, six species have medicinal value, three species are inedible and three are unknown. The maximum density of occurrence was exhibited by Psilocybe cubensis (45%) followed by Lepiota sp. (40%), Ganoderma pfeifferi (35%) and Ganoderma lucidum (25%). The present investigation emphasized the existence of a distinct biodiversity in mushroom population at National Botanical Garden, Dhaka.
