Taxonomy

Collection 1000410 (herbarium acc. no. MICH 10756) is Hebeloma album. It is the holotype of heterotypic synonym Hebeloma kanouseae A.H. Sm., V.S. Evenson & Mitchel [as "kanousiae"] (1983).

Description

Collecting details

Collection 1000410 was collected by B.B. Kanouse, det: A.H. Smith on 28th August 1923 in Carbon County, Medicine Bow Mountains, Wyoming, UNITED STATES (approx. 41.0361°N, 106.1722°W, altitude approximately 2800 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Populus) was present.
The surrounding habitat was described as subalpine bog verge with a substrate of boggy soil and litter, 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. 5.4: Wetlands (inland) – Bogs, marshes, swamps, fens, peatlands.
According to the GPS data the collection was in the Colorado Rockies 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.
