Abstract

The genus Lactarius (Basidiomycetes) is distributed worldwide and is characterized by colorful basidiomata,
which exude latex. On this study were analyzed, with the purpose of identifying the species where they belong. 28 dried mushroom samples of Lactarius, attached to Uvidus and Zonarii Sections, collected in Guatemala and placed at the Micoteca “Rubén Mayorga Perlata”-MICG- (herbarium) of the Faculty of Chemistry and Pharmacy, University of San Carlos of Guatemala. Spores, their crests and Q index were analyzed (length / width ratio). It also was analized the size of basidia, sterigmata, pleurocystidia, cheilocystidia, and pilleipelis structure; as well were analyzed qualitative characteristics such as microstructures reaction of Melzer’s reagent and presence incrustations in hyphae. It was found that the microstructures of six samples match in shape and dimensions with Lactarius mexicanus, L. psammicola, L. chrysorheus. 23 are related to L. uvidus. This study confirms the presence of species In Guatemala which were only reported in North America such as L. montanus, L. mexicanus or separately reported in Costa Rica as L. psammicola.
