- arrow_drop_downarrow_drop_upCollecting details
Collection 19927 was collected by N. Siegel (4592) on 19th October 2019 in Black Diamond Camp, at Buck Creek, near Greenwater, Pierce Co., Washington, UNITED STATES (approx. 47.022°N, 121.5524°W, altitude approximately 800 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genera Pseudotsuga, Abies and Tsuga) was present.
The surrounding habitat was described as not recorded with a substrate of nutrient-enriched soil and dung.
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).
