CORDOVA-CHAVEZ, Octavio et al. Evaluation of ecto-micorrizical fungi from the basidiomicetes group in the zone of Cofre de Perote, Veracruz, Mexico. Madera bosques [online]. 2014, vol.20, n.1, pp.97-106. ISSN 2448-7597.

The Cofre de Perote region is located in the southern part of the Sierra Madre Oriental, located in the area of the Parque Nacional Cofre de Perote which presents high rates of deforestation, and practically the spruce forests are gone. This region is home to a large number of fungal species, some highly valued in the local and national markets. The ecological importance played by fungi in the forests is more appreciable when the ectomicorrhizic symbiosis is taken into account. Among the ectomycorrhizal fungi, Basidiomycetes are more diverse and important given that among them are several edible species, and for this reason, the present work aims to quantitatively assess the species belonging to this group of fungi in six locations in the region of the Cofre de Perote. The diversity of ectomycorrhizal fungi in six locations of the volcano Cofre de Perote, Veracruz, comprised 53 basidiomycete species assigned to 22 genera, 15 families and 6 orders. Twenty-one species were found to be edible and all of them are sold in the market of Xalapa. Species diversity estimated by the Shannon-Wiener index ranged between 1.73 and 3.25. The most diverse locality during the period of the study was El Conejo (Abies forest) and the least diverse was the San Juan del Monte Reserve (Pinus forest). The most abundant families were Amanitaceae, Bankeraceae, Boletaceae, and Russulaceae. The species found in most of the localities were Amanita muscaria, Boletus edulis and B. pinophilus.
