A checklist of Ascomycota from Mexico.

Mexico, with a land surface area of 1.97 M sq. km., has a topography that varies from high plains in the north, to tall volcanic mountains in the south-central region, to lowlands in the south, as well as extensive coastlines. Southern Mexico is the area where the temperate climate of North America unites with the tropical climate of Central and South America, resulting in a highly diverse country (the fourth most megadiverse country of the world) with 131 ecoregions (75 terrestrial and 56 marine) that supports an abundant biota, including ascomycetes. The mycological literature was reviewed for records of ascomycetes from Mexico, which yielded 1,598 species plus 31 varieties/forms, for a total of 1,629 identified taxa of ascomycetes known from the country. Of the 1,629 taxa, only 54 are from aquatic environments (47 marine and 7 freshwater species). Approximately 33% of genera and 38% of the species are lichenized. The anamorphic ascomycetes were not included in this compilation. Taxonomically, these ascomycetes are arranged in 452 genera in 48 orders (+ incertae sedis) and 133 familes (+ incertae sedis). The Xylariales is the best studied group. With regard to geographical distribution, the most explored areas in the country are the States of Veracruz, Mexico, Oaxaca and the State of Chiapas, located in the central-southeast region of the country. The complete inventory of Ascomycota from Mexico is available online at http://naturalhistory.uga.edu/~GMNH/Mycoherb_Site/cklists/cklist.htm. Information on the distribution, classification and references are provided for each species in the list.
