Collection 18896 was collected by N. Siegel (3594) on 28th January 2019 in Samoa Dunes, Humboldt County, California, UNITED STATES (approx. 40.7629°N, 124.226°W, altitude approximately 0 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genera Abies and Pinus) was present.
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).
