Siegel (3534) on 9th January 2019 in Santa Clara Co, San Jose, Metcalf Park , California, UNITED STATES (approx. 37.2363°N, 121.7201°W, altitude approximately 380 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the California interior chaparral and woodlands 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).
