Collecting details

Collection 1000400 was collected by W.A. Murrill on 11th January 1945 in Gainesville, Alachua Co., Florida, UNITED STATES (approx. 29.6516°N, 82.3248°W, altitude approximately 50 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as lawn 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. 14.5: Urban Areas.
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).
