- arrow_drop_downarrow_drop_upCollecting details
Collection 1000547 was collected by K. Soop on 17th April 1999 in Walker Creek Rest Area, Te Anau, South Island, NEW ZEALAND (approx. 45.1006°S, 167.9684°E, altitude approximately 270 m above sea level - Google maps). The ectomycorrhizal family Nothofagaceae (genus Nothofagus) was present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the New Zealand South Island montane grasslands 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.Image gallery
