- arrow_drop_downarrow_drop_upCollecting details
Collection 14410 was collected by H.J. Beker, L. Davies on 12th October 2014 in Mt Ranier Nat Park, Washington, UNITED STATES (46.7682°N, 121.7928°W, altitude approximately 1040 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genera Abies, Pseudotsuga and Tsuga) was present.
The surrounding habitat was described as coniferous, subalpine woodland with a substrate of mossy soil, 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. 1.1: Forest – Boreal.
According to the GPS data the collection was in the Central-Southern Cascades 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).

(biome: Temperate Conifer Forests) and Koppen climate code Dfb (Cold, no dry season, warm summer).
