- arrow_drop_downarrow_drop_upCollecting details
Collection 1000383 was collected by T. Hongo, H. Clémençon (HC-88/95) on 15th August 1988 in Tomikawa, Otsu-shi, Shiga-ken, Kansai, JAPAN (approx. 34.9001°N, 135.9489°E, altitude approximately 180 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pinus) and Fagaceae (genus Quercus) were present.
The surrounding habitat was described as woodland with a substrate of 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. 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).
