Description

Collecting details

Collection 13133 was collected by P.-A. Moreau (PAM- 03082305) on 25th August 2003 in Peisey-Nancroix, Les lanches en aval de Bellecote, Savoie, FRANCE (approx. 45.5246°N, 6.7916°E, altitude approximately 1530 m above sea level - Google maps). The ectomycorrhizal family Betulaceae (genus Alnus) was present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Alps conifer and mixed 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).

(biome: Temperate Conifer Forests) 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.
