VILLANUEVA-JIMENEZ, Emmanuel; VILLEGAS-RIOS, Margarita; CIFUENTES-BLANCO, Joaquín  y  LEON-AVENDANO, Hugo. Diversity of the genus Amanita in two areas with different forestry management in Ixtlán de Juárez, Oaxaca, Mexico. Rev. Mex. Biodiv. [online]. 2006, vol.77, n.1, pp.17-22. ISSN 2007-8706.

The diversity of Amanita species occurring 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 correspond to 36 species, 21 belonging to the subgenus Amanita and 15 to the subgenus Lepidella; 14 represent first records in Oaxaca state and 19 to Ixtlán of Juarez County in particular. The abundance of species within a year was correlated with the precipitation and ecological conditions. Twenty species appeared once and the most frequent were: Amanita flavoconia var. sinapicolor, A. flavoconia var. flavoconia, A. virosa, A. flavoconia var. inquinata, A. xylinivolva, A .muscaria var. flavivolvata y A. arocheae. These findings encourage for further studies in the community of Ixtlán, where infrequent species of Amanita and other ecological data may be obtained.
