“Yungas Andinas” is the name of the mountain forests in northwest Argentina. "Sierra de San Javier" Park belongs to the Universidad Nacional de Tucumán and is located in this area. We studied specific yeast communities associated with "Laurel del Monte" (Phoebe porphyria). The objective was to isolate yeast strains and analyze their metabolic and genetic diversity. Yeasts was isolated from  alive and dead parts of plants. A preliminary identification of isolated yeasts was made according to conventional techniques. These studies showed some limitations for identification of new isolates, since there was not a 100% matching with reference strains profiles. This work was followed by using molecular techniques based on amplification, restriction fragment length polymorphism analysis (RFLP) and sequence analysis of rDNA.Phylogenetic studies based on 26S  sequences showed that the isolated yeast belongs to the ascomycetous yeasts
