Collection 17011 was collected by E. Matthews on 25th January 2017 in Between McKinleyville and Fieldbrook, Humboldt County, California, UNITED STATES (approx. 40.9574°N, 124.0746°W, altitude approximately 160 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as not recorded with a substrate of cadaveric soil.
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).
