Collection 19361 was collected by N. Siegel (4128) on 16th May 2019 in Awakeri, 791 White Pine Bush Road, Marcus Baker's land, North Island, NEW ZEALAND (approx. 38.0312°S, 176.9633°E, altitude approximately 20 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as not recorded with a substrate of soil and litter.
According to the GPS data the collection was in the New Zealand North Island temperate 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).
