The result of the flora diversity study indicated that there were rich fungal flora in the Daqinggou Nature Reserve in Inner Mongolia of China. The dominant families are Tricholomataceae ,Coriolaceae ,Cortinariaceae , Agaricaceae ,Strophariaceae , Hygrophoraceae and Xylariaceae , while the dominant genera are Inocybe , Marasmius , Polyporus , Pholiota , Pluteus , Xylaria , A garicus , Rhodophyllus , Hygrophorus , Hygrocybe , Crepidotus , Melanoleuca , Trametes and Helvella. Regarding the composition , the species were grouped into : Cosmopolitan (34. 11 %) , North Temperate Zone (42. 05 %) ,North Temperate-Australia (5. 30 %) , Temperate- subtropical or Tropical (3. 31 %) , Eurasian (2. 98 %) , Eastern Asia-North America (2. 32 %) , Eastern Asia(1. 97 %) , Sino-Japan in common(4. 64 %) , and endemic(3. 97 %) . In all nine distributional types , cosmopolitan and North Temperate Zone are characteristics of this region. The fungal flora of Daqinggou is very similar to that of the Changbai Mountains in Northeast China. This suggests that the origins of these two floras may have a certain relationship , but they have no close relationship with the fungal flora in subtropical and tropical regions.
