BIODIVERSITY AND MORPHOLOGICAL CHARACTERIZATION OF GANODERMA SPP. FROM TROPICAL MOIST DECIDUOUS FOREST REGION OF BANGLADESH

Abstract

An investigation was carried out to collect, identify and preserve Ganoderma spp. on the basis of morphological characteristics from Pabna, Dhaka and Rajshahi under the tropical moist deciduous forest region in Bangladesh during June to September 2016 and July to October 2017 to record the morphological variability, distribution, habitat, and biodiversity of the Ganoderma population. A total of 40 Ganoderma samples were collected and identified to eight species under Ganodermataceae family. The highest density of occurrence (23%) was recorded for Ganoderma lucidum followed by Ganoderma applanatum (20%), Ganoderma praelongum (19%), Ganoderma lesklokorka (18.5%), Ganoderma pfeifferi (17%), Ganoderma boninense (15%), Ganoderma lipsiense (13%) and Ganoderma tsugae (11%). The highest frequency of occurrence (10%) was recorded for Ganoderma applanatum followed by Ganoderma lucidum (9%), Ganoderma pfeifferi (8%), Ganoderma boninense (8%), Ganoderma praelongum (7%), Ganoderma lesklokorka (7%), Ganoderma tsugae (6%) and Ganoderma lipsiense (5%). During survey, Albizia procera (Koroi), Terminalia arjuna (Aurjun), Dalbergia sissoo (Sisso plant), Azadirachta indica (Neem), Acacia auriculiformis (Golden shower) and Albizia lebbeck (Rain tree) were found as hosts of Ganoderma spp. The specimens were preserved in the SAU Herbarium of Macro fungi ( SHMF).
