摘要：The distribution and endemicity patterns of Gomphales in Mexico are analyzed here for the first time. Richness and corrected endemism were obtained from a dataset of 3,483 records for 97 species, using a cell-grid system of one degree per side. The central region of Mexico (Tlaxcala, Veracruz, Hidalgo and Estado de México states), which includes most of the Trans-Mexican Volcanic Belt and Sierra Madre Oriental biogeographic provinces, had the highest richness values, but Mexican areas in the Pacific Coast (Jalisco and Michoacán states) and southeastern Mexico (Oaxaca and Chiapas states) had the most distinctive composition, as measured by the corrected endemism index. Two main distributional patterns were recovered: a) montane: at elevations above 1000 m on coniferous, pine-oak, oak and cloud forests, typified by the presence of species of Ramaria and Clavariadelphus, b) lowlands: at elevations below 1000 m mainly in evergreen, rainforest and deciduous tropical forests characterized by the presence of four tropical species of Lentaria , two tropical species of Gomphus endemic to Mexico, and four tropical species of Phaeoclavulina . The eight species of Gomphales endemic to Mexico have very restricted distribution, mostly in non-protected areas, and are not considered under special protection programs. The present contribution delineates general patterns of distribution for the Gomphales, and documents its diversity and endemism in Mexico.
