- arrow_drop_downarrow_drop_upCollecting details
Collection 1000342 was collected by P.S. Catcheside (PSC1222), det: B.J. Rees on 7th July 2002 in Region 11: Southern Lofty. Kuitpo Gate, Gate 52. Near meadows, South Australia, AUSTRALIA (approx. 35.2211°S, 138.7114°E, altitude approximately 350 m above sea level - Google maps). The ectomycorrhizal family Myrtaceae (genus Eucalyptus) was present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Murray-Darling woodlands and mallee 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).
