- arrow_drop_downarrow_drop_upCollecting details
Collection 1000441 was collected by H.T. Tisdall (No 2) on 14th July 1888 in Sandringham, Victoria, AUSTRALIA (approx. 37.9496°S, 145.0037°E, altitude approximately 20 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as not recorded with a substrate of sandy soil.
According to the GPS data the collection was in the Southeast Australia temperate 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).
