Description

Collecting details

Collection 1000299 was collected by Field Naturalists Club of Victoria on 15th June 2006 in Warburton, Upper Yarra Resevoir between Water Wheel and bridge to Dr's Creek Walk, Victoria, AUSTRALIA (37.6731°S, 145.8831°E, altitude approximately 320 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Eastern Australian 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).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
