Research on the useful mushroom was done at Aurora Memorial National Park (AMNP). The Park is situated in Central Luzon Region with a total land area of 5,676 hectares. AMNP has no distinct wet and dry season thus provides a favorable climate, which promotes the growth of useful mushrooms. The photo-documentation and collections were performed to assess diversity. Five Transect Lines (TL) were laid out in five areas, with 20m x 30m quadrat and interval of 100 meters between quadrats. The study resulted in the identification of 36 families, 53 genera, and 104 species of which 97 are basidiomycetes and 6 are ascomycetes. Simpson’s and Shannon diversity indexes resulted in 0.7254 and 1.4295, respectively. In both indexes, useful mushrooms at AMNP showed moderately diverse. While the evenness revealed 0.1565 indicating low species evenness in each TL. Among the significant findings revealed two new possible new species of Microporus and Cymatoderma.
