Abstract
Fifteen species of the genus Entoloma, found in high elevations of Nevado de Colima and the Tequila volcanos, both in the state of Jalisco, Mexico, are presented. Their macromorphological and micromorphological structures are described and general characteristics of their habitat; furthermore, comments about their distinctive features and similar species in the literature are given. Of these 15 species, three are described as new, 11 represent the first records for Mexico, and the remaining one is the second record for the country. The species generally show much resemblance to Entoloma taxa described from the Southern United States of America and to a lesser extent, those of Europe.
