Taxonomy

Collection 11214 is Hebeloma laterinum.

Description

Collecting details

Collection 11214 was collected by J. Weir on 3rd October 2004 in Trowbarrow, North Lancashire, ENGLAND (approx. 54.17°N, 2.79°W, altitude approximately 40 m above sea level - Google maps). The ectomycorrhizal family Cistaceae (genus Helianthemum) was present.
The surrounding habitat was described as not recorded with a substrate of sandy soil.
According to the GPS data the collection was in the Celtic broadleaf 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). Use this webtool to explore the ecoregions visually or see a full list of current ecoregions on Wikipedia. (biome: Temperate Broadleaf & Mixed Forests) and Koppen climate code Cfb (Temperate, no dry season, warm 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.
