Description

Collecting details

Collection 12414 was collected by S.A. Elborne, det: J. Vesterholt (86-489) on 21st August 1986 in Pohjois-Häme, Äänekoski, Parantala, FINLAND (approx. 62.64°N, 25.51°E, altitude approximately 135 m above sea level - Google maps). The ectomycorrhizal family Betulaceae (genus Betula) was present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Scandinavian and Russian taiga 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). Use this webtool to explore the ecoregions visually or see a full list of current ecoregions on Wikipedia. (biome: Boreal Forests/Taiga) and Koppen climate code Dfc (Cold, no dry season, cold summer).

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.
