摘　　要：对重庆大巴山自然保护区大型真菌资源及其区系特征进行了研究.结果:保护区有大型真菌53科111属181种,其中木生真菌97种、寄生真菌3种、土生真菌81种;含5种以上的科为多孔菌科、伞菌科、红菇科、小皮伞科、口蘑科、牛肝菌科、球盖菇科、刺革菌科、鹅膏菌科、小伞科;含4种以上的属为红菇属、鬼伞属、皮伞属、多孔菌属、鹅膏菌属、马勃属、小菇属、灵芝属;从属的组成上可划分为世界分布属(73.87%)、泛热带分布属(13.51%)和北温带分布属(12.62%),表现出从亚热带向北温带过渡的区系特征.在区系亲缘关系上与湖北和陕西较为接近,而与川西地区的区系较为疏远.The macromycetes in Dabashan Natural Reserve in Chongqing are investigated and their floristic characteristics are studied. The samples collected include 181 species, belonging to 111 genera 53 families, of whieh 97 are lignieolous, 3 are parasitical and 81 are humicolous species. Polyporaceae9 Agaricaceae, Russulaceae, Marasmiaeeae, Trieholomataceae, Boletaceae, Strophariaceae, Hymenocbaetaceae, Aman- itaceae and Mycenaceae are the dominant families, each having 5 species or more. Russula, Coprinus, Marasmius, Polyporus, Amanita, Lycoperdon, Mycena and Ganoderma are the dominant genera, each having 4 species or more. Regarding their floral composition, the genera were grouped into 3 geographical elements, i.e. Cosmopolitan element （73.87%）, Pantropical element （13.51%） and North Temperate el- ement （12.62%）, suggesting a striking floral characteristic of transition from subtropical to north temper- ate distribution. The macrofungal flora of Dabashan is very similar to that of Hubei province and Shanxi province. 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 western Sichuan.
