This study aimed to examine species diversity of wild mushrooms and the influence of environmental factors on the occurrence of them in dry dipterocarp forest (DDF) and dry evergreen forest (DEF) in Sakaerat Environmental Research Station, Nakhon Ratchasima province. In each forest type, a mushroom survey was conducted in 90 m x 90 m permanent plot, which was divided into 3 subplots with 30 x 90 m. Additionally, environmental factor data including air temperature, soil temperature, soil moisture content, crown cover, soil pH, soil texture, organic matter, macro element (C, P, Ca, Mg) were measured in the plots during September to November 2015. Results from surveys revealed 76 species, which were 71 identified mushroom species and 5 unidentified species. The identified species were classified in 39 genera 22 families 11 orders. Among of them, family Russulaceae had the highest in the number of species (10 species), followed by family Marasmiaceae (7 species). The diversity index in DDF (H’ = 2.67) was higher than DEF (H’ = 2.23). However, the similarity index of both forest types was low (SI = 11.17). Marasmiellus candidus (22.39 %) was the most abundant mushroom species in DDF, while Dicephalospora rufocornea (41.71 %) was the abundant species in DEF. The relationship between mushrooms in DDF and DEF with environmental factors analyzed by the ordination method with canonical correspondence analysis (CCA) can be divided into 4 groups, including (1) the group had positively related to the crown cover and available phosphorus, (2) the group had positively related to soil moisture, (3) the group had positively related to air temperature, soil temperature, light density, exchangeable Mg, exchangeable Ca, total carbon, soil organic matter, top soil pH, and (4) the group was generalist species.
