This study is a contribution to the biodiversity and community structure of clavarioid Agaricomycetes in the tropical forests of the Chamela Biological Station, in Jalisco, Mexico. The collections were made during the rainy seasons from 2005 to 2008 during which we recorded the morphological and ecological information, including basidiocarp morphology and patterns of growth. Likewise, records were also taken for habitat preferences, types of substrate, orientation, slope inclination, range of distribution and abundance. The 86 specimens recorded, corresponded to 17 different species, from which Physalacria changensis, P. inflata, Pterula verticillata and Scytinopogon scaber are new records for Mexico. The species S. pallescens, Pterula sp. 2 and Thelephora sp. were the most abundant, while other 6 species were observed only once. Results suggested a non-random distribution of the basidiomes, showing clear preferences of these fungi to fruit in the southern slopes of tropical evergreen forest vegetation at angles from 21° to 30°.
