Collection 14850 was collected by T. Læssøe on 20th August 2015 in Thoum, Muang Khoun, Xiangkhouang, LAOS (19.3149°N, 103.4097°E, altitude approximately 1135 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as deciduous, montane, tropical 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 Luang Prabang montane rain 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).
