Resumen:
Background: We performed an ethnomycological study in a community in Tlaxcala, Central Mexico to identify the most important species of wild mushrooms growing in an oak forest, their significance criteria, and to validate the Cultural Significance Index (CSI).Methods: Thirty-three mestizo individuals were randomly selected in San Mateo Huexoyucan and were asked seven questions based on criteria established by the CSI. Among the 49 mushroom species collected in the oak forest and open areas, 20 species were mentioned most often and were analyzed in more detail. Ordination and grouping techniques were used to determine the relationship between the cultural significance of the mushroom species, according to a perceived abundance index, frequency of use index, taste score appreciation index, multifunctional food index, knowledge transmission index, and health index.Results: The mushrooms with highest CSI values were Agaricus campestris, Ramaria spp., Amanita aff. basii, Russula spp., Ustilago maydis, and Boletus variipes. These species were characterized by their good taste and were considered very nutritional. The species with the lowest cultural significance included Russula mexicana, Lycoperdon perlatum, and Strobylomyces strobilaceus. The ordination and grouping analyses identified four groups of mushrooms by their significance to the people of Huexoyucan. The most important variables that explained the grouping were the taste score appreciation index, health index, the knowledge transmission index, and the frequency of use index.C onclusions: A. aff. basii and A. campestris were the most significant wild mushrooms to the people of San Mateo. The diversity of the Russula species and the variety of Amanita and Ramaria species used by these people was outstanding. Environments outside the forest also produced useful resources. The CSI used in Oaxaca was useful for determining the cultural significance of mushrooms in SMH, Tlaxcala. This list of mushrooms can be used in conservation proposals for the Quercus forests in the area. © 2014 Alonso-Aguilar et al.; licensee BioMed Central Ltd.
