- arrow_drop_downarrow_drop_upCollecting details
Collection 1000449 was collected by W.A. Murrill on 28th December 1942 in Gainesville, Florida, UNITED STATES (approx. 29.675°N, 82.3417°W, altitude approximately 50 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as not recorded with a substrate of soil.
According to the GPS data the collection was in the Southeast US conifer savannas 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).
