- arrow_drop_downarrow_drop_upCollecting details
Collection 1000248 was collected by C.H. Kauffman, A.H. Smith (18) on 8th September 1929 in Rock River, Michigan, UNITED STATES (approx. 46.3379°N, 86.9891°W, altitude approximately 300 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Cedrus) was present.
The surrounding habitat was described as not recorded with a substrate of boggy, mossy soil.
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).
