Abstract：To explore the species diversity of macrofungi in Baihe National Nature Reserve，Sichuan province，the distribution of macrofungiat different altitudes in thereservewas investigated with the line transect method and the stepping method.The results show that there are 15O species of macrofungi in the reserve，belonging to 86 genera，50 families，18 orders，6 classes，and 2 phylums，and supplementing 10 newly recorded species in Sichuan province.Among them，there are 52 species of predominant families， including Russulaceae，Polyporaceae and Boletaceae，accounting for around 34.67% of the total species， and 32 species of dominant genera，including Russula，Lactarius，Pleurotus，and Amanita，accounting for

21.33% .The diversity and richness of macrofungi are highest in mixed coniferous and broad-leaved forests at the altitude of 2000～2500 meters，and the richness of macrofungi first increases and then decreases with the increase of altitude.There are 67 species of edible fungi，62 species of medicinal fungi，31 species of poisonous fungi，37 species of ectomycorrhizal fungi，43 species of wood-decay fungi in thereserve.The distribution of the macrofungi flora in the reserve shows obvious cosmopolitan characteristics， with the cosmopolitan element accounting for 61.63% ofthe total genera，followed by the north temperate element，which accounts for 19.77% .The diversity of macrofungi in Baihe National Nature Reserve is rich，with great prospects for the development and utilisation of fungal resources，and its distribution is closelyrelatedtoaltitude.
