Fungi are eukaryotic, spore-forming, non-chlorophyll organisms and reproduce sexually and asexually. Fungi have an important role in forest ecosystems as decomposers and can also parasitize other plants. The presence of fungi is important in the forest ecology because the presence of fungi can accelerate the process of decomposition of wood on the forest floor into litter. Inventory and identification are carried out in order to find out the types of fungi that exist and how they are spread. The method used is purposive sampling with a plot size of 20m x 20m in 3 areas in 1 line transect. Mushrooms that can be calculated the Importance Value Index. The areas taken are sloping areas, closed areas and open areas. 12 species of fungi were identified from 110 individuals found. In the sloping area found 2 species with marasimus vaillanti with the highest IVI is 107%. In a closed area found 3 species of fungi with mycena piprerygia with the highest IVI of 97.1%. The open area found 9 species with Daldania concentrica with the highest IVI of 33.2%. Mushrooms are most commonly found in open areas because the temperature, humidity, and light intensity are in accordance with the needs of mushroom life
