Description

Collecting details

Collection 16565 was collected by O. Ceska on 23rd November 2007 in Victoria, Saanich Peninsula, Observatory Hill; along the paved road, just above the main gate, British Columbia, CANADA (approx. 48.5263°N, 123.422°W, altitude approximately 150 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pseudotsuga), Ericaceae (genus Arbutus) and Fagaceae (genus Quercus) were present.
The surrounding habitat was described as mixed woodland roadside verge, 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. 1.4: Forest – Temperate.
According to the GPS data the collection was in the Puget lowland 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.
