In this article,macrofungi from Longnan mountain,Gannan plateau,Longzhong loess plateau,Qilian mountain and natural grassland of Gansu province were collected and identified in detail. Also,dominant families and genera were analyzed.The results showed that the 699 samples were collected and 346 species belonged to 92 genera,38 families,12 order,5 classes,2 phyla. In total,there were 4 dominant families in Gansu,such as Russulaceae,Polyporaceae,Tricholomataceae,Boletaceae,including 51,50,46,29 species respectively. There were two dominant genera in Gansu,such as Russula,Cortinarius,including 42,27 species respectively. In Longnan mountain,the 5 dominant families which contained 53,50,32,28 and 17 species in proper order were Russulaceae,Polyporaceae,Boletaceae,Tricholomataceae,Amanitaceae. The dominant genera were Russula,Amanita,Lactarius,Boletus,containing 39,16,14 and 12 species. In Gannan plateau,the dominant families were Tricholomataceae which had 15 species. The dominant genera were Mycena,Melanoleuca,containing 6 and 5 species. In Longzhong loess plateau,the dominant familie were Tricholomataceae which had 14 species. The dominant genera were Clitocybe,Ramaria,Helvella,Agaricus,Boletus with the most species（ 4 ~ 7）. In Qilian mountain,the 2 dominant families which contained28 and 26 species were Cortinariaceae,Tricholomataceae. The dominant genera were Cortinarius with 24 species.
