- arrow_drop_downarrow_drop_upCollecting details
Collection 14852 was collected by T. Læssøe, O. Pedersen on 18th August 2015 in Laethong, Phoukhout, Xieng Khouang, LAOS (19.7424°N, 103.2581°E, altitude approximately 1135 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genera Fagus, Lithocarpus and Castanopsis) was present.
The surrounding habitat was described as 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).
