ESQUEDA, Martín et al. New records of gasteroid fungi in the Sierra de Álamos-Río Cuchujaqui Biosphere Reserve. Rev. Mex. Mic [online]. 2011, vol.34, pp.43-51. ISSN 0187-3180.

With the purpose of contributing to the knowledge of taxonomy and ecology of gasteroid fungi, 10 areas were sampled in the Sierra de Álamos-Río Cuchujaqui Biosphere Reserve, located in Sonora, Mexico. The survey was conducted during the four seasons of the year in five vegetation types. Twenty-two species of gasteroid fungi were determined, comprised in 11 genera, 4 families and 2 orders: Order Agaricales: Agaricaceae (11 spp.), Diplocystidiaceae (1), Sclerodermataceae (1); Order Geastrales: Geastraceae (9). The most species-rich genus was Geastrum with 7 taxa. The highest number of species was found fruiting during summer (11) and autumn (11) in tropical deciduous forest.
