- arrow_drop_downarrow_drop_upCollecting details
Collection 14700 was collected by H.J. Beker, L. Davies on 21st September 2015 in Linville Falls, North Carolina, UNITED STATES (35.9491°N, 81.9311°W, altitude approximately 985 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genera Betula, Carpinus and Ostrya), Pinaceae (genera Pinus and Tsuga) and Fagaceae (genera Quercus and Fagus) were present.
The surrounding habitat was described as mixed woodland with a substrate of mossy soil and litter, 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. 1.4: Forest – Temperate.
According to the GPS data the collection was in the Appalachian-Blue Ridge 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).
