Diversidad del género Amanita en dos áreas con diferente condición silvícola en Ixtlán de Juárez, Oaxaca, México

Abstract

The diversity of Amanita species in two areas of Pinus-Quercus forest with different management in the community of Ixtlán de Juárez, Oaxaca, was studied. The samples were collected during the wet season. The 107 specimens collected represented 36 species, 21 belonging to the subgenus Amanita and 15 to the subgenus Lepidella; 14 represent first records in Oaxaca state and 19 in Ixtlán de Juárez County in particular. The abundance of species within a year was correlated with the precipitation and ecological conditions. Twenty species appeared once; of the remaining 15 species, the most frequent were: Amanita flavoconia var. sinapicolor, A. flavoconia var. flavoconia, A. virosa, A. flavoconia var. inquinata, A. xylinivolva, A .muscaria var. flavivolvata and A. arocheae. Our findings show the need for further studies in the community of Ixtlán, where infrequent species of Amanita and other ecological data may be obtained.
