Collection 17412 was collected by U. Kawasaki (338) on 20th 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 mixed woodland, 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. 1.4: Forest – Temperate.
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). Use this webtool to explore the ecoregions visually or see a full list of current ecoregions on Wikipedia. (biome: Temperate Broadleaf & Mixed Forests) and Koppen climate code Cfa (Temperate, no dry season, hot summer).
