- arrow_drop_downarrow_drop_upCollecting details
Collection 16978 was collected by L. Davies, H.J. Beker on 11th September 2017 in M95, near The Basin, Michigan, UNITED STATES (46.4121°N, 87.9931°W, altitude approximately 475 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Betula) and Pinaceae (genus Pinus) were present.
The surrounding habitat was described as mixed woodland roadside carpark with a substrate of grassy 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 Western Great Lakes 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).
