- arrow_drop_downarrow_drop_upCollecting details
Collection 1000274 was collected by R.A. Harper (55), det: W.A. Murrill on 20th February 1911 in Berkeley, California, UNITED STATES (approx. 37.8716°N, 122.2727°W, altitude approximately 50 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as lawn with a substrate of nutrient-enriched soil, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 14.5: Urban Areas.
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).
