Description

Collecting details

Collection 15850 was collected by T. Fukiharu on 25th September 1996 in Futaba-gun, Naraha-machi, Kidogawa valley, Otaki Shrine, Plot 95-70, Fukushima, JAPAN (approx. 37.2728°N, 140.9274°E, altitude approximately 150 m above sea level - Google maps). The ectomycorrhizal families Fagaceae (genus Quercus) and Pinaceae (genus Pinus) were present.
The surrounding habitat was described as not recorded with a substrate of nutrient-enriched, urea-treated soil.
According to the GPS data the collection was in the Taiheiyo montane deciduous 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).

(biome: Temperate Broadleaf & Mixed Forests) and Koppen climate code Cfa (Temperate, no dry season, hot summer).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
