- arrow_drop_downarrow_drop_upCollecting details
Collection 18632 was collected by R. Lebeuf on 1st September 2018 in Radisson, Loup, Quebec, CANADA (approx. 53.8°N, 77.61°W, altitude approximately 175 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Alnus), Salicaceae (genus Salix) and Pinaceae (genus Picea) were present.
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 Eastern Canadian Shield taiga 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).
