- arrow_drop_downarrow_drop_upCollecting details
Collection 17809 was collected by N. Siegel (2443) on 19th November 2017 in HBMS Show, Humboldt (or Trinity) Co., California, UNITED STATES (approx. 40.7799°N, 124.1279°W, altitude approximately 50 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Northern California coastal 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).
