Abstract: This paper reports the composition and ecological distribution of soil fungi in the Gaoligong Moun-tains State Nature Reserve in Yunnan Province. Twenty-eight genera belonging to 3 classes, 6 orders, and 11 families are founded in the region. The predominant families are Moniliaceae (11 genera, 37.9 of the total genera) and Dematiaceae (5 genera, 17.2). All the specimens are deposited in Microorganism E-cology Laboratory of at the Xishuangbarma Tropical Botanical Garden, Chinese Academy of Sciences, Kun-ming. The number of genera of the soil fungi is the highest in original forests at elevation of about 2000 m above sea level, lower in original forests at high elevation, and the lowest in the secondary forests at low ele-vation. The pattern of fungal quantity is similar to that of generic number.
