Collection 19959 was collected by N. Siegel (4683) on 6th December 2019 in South Fork Smith River, Rock Creek Camp, Del Norte Co., California, UNITED STATES (approx. 41.7329°N, 123.9801°W, altitude approximately 140 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pseudotsuga) and Fagaceae (genera Notholithocarpus and Quercus) were present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Klamath-Siskiyou 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).
