    Collection 16227 was collected by Y. Koizumi on 30th September 2012 in Tokamacho shi Matsunoyama Matsuguchi beautiful forest (C course), Niigata, JAPAN (approx. 37.0835°N, 138.6016°E, altitude approximately 430 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Fagus) was present.

    The surrounding habitat was described as 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 Nihonkai 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).
