Collection 17733 was collected by A. Montoya-Esquivel (E3102) on 23rd July 2017 in Municipality of Panotla, 1 Km al Este de San Francisco Temezontla, Tlaxcala, MEXICO (approx. 19.3497°N, 98.2784°W, altitude approximately 2600 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as coniferous, montane, subtropical woodland, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 1.9: Forest – Subtropical/tropical moist montane.
According to the GPS data the collection was in the Trans-Mexican Volcanic Belt pine-oak forests WWF ecoregion The World Wildlife Fund (WWF) have divided the world into 867 terrestrial ecoregions. The ecoregion here is estimated by mapping from the GPS coordinates of the collection using data made available by Dinerstein et al (2017).
