江西井冈山国家级自然保护区大型木生真菌物种多样性OA

To reveal species diversity of wood-inhabiting macrofungi in the Jinggangshan National Nature Reserve,a systematic investigation and specimen collection was conducted in the nature reserve.In total 2 377 specimens were collected.Using an integrated approach combining morphological observation and molecular biological identification,a total of 243 species of wood-inhabiting fungi was identified,belonging to 139 genera,45 families,13 orders,7 classes and 2 phyla.Among them,species of Polyporaceae and Hymenochaetaceae are dominant,accounting for 33.33%of the total species.Eight genera including Trametes were identified as dominant genera,comprising 51 species and representing 20.99%of the total species.In terms of funga,the fungi were dominated by cosmopolitan genera(accounting for 56.83%of the total genera)and tropical-subtropical-distributed genera(10.07%),reflecting the typical characteristics of mid-subtropics.In addition,50 species with important economical values were detected,including 6 edible species,37 medicinal species and 7 species with both edible and medicinal properties.The results provide a scientific basis for the conservation,exploitation and biodiversity research of this regional nature resources.
