Collection 17414 was collected by U. Kawasaki (350) on 27th October 2017 in Tsukuba, Ibaragi, Kanto, JAPAN (approx. 36.085°N, 140.12°E, altitude approximately 25 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Taiheiyo evergreen 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).
