Taxonomy

Collection 11811 (herbarium acc. no. IB19860338) is Hebeloma pumilum.

Description

Collecting details

Collection 11811 was collected by M. Moser on 7th October 1986 in Val di Taro, Parma, Emilia-Romagna, ITALY (approx. 44.8°N, 10.33°E, altitude approximately 55 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Fagus) was present.
The surrounding habitat was described as not recorded with a substrate of soil and litter.
According to the GPS data the collection was in the Po Basin 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 Broadleaf & Mixed Forests) and Koppen climate code Cfa (Temperate, no dry season, hot 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.
