  • arrow_drop_downarrow_drop_upCollecting details

    Collection 18746 was collected by Z.W. Ge (GE1114) on 27th July 2006 in Zhongdian Xian: along old road between Qiaotou and Zhongdian, south of Xiao Zhongdian, Yunnan, CHINA (approx. 27.4758°N, 99.8842°E, altitude approximately 3280 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pinus) and Fagaceae (genus Quercus) were present.

    The surrounding habitat was described as mixed, 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 Hengduan Mountains subalpine conifer 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).
