Taxonomy
Collection 1000134 (herbarium acc. no. PERTH 01012665) is Hebeloma aminophilum. It is the holotype of heterotypic synonym Hebeloma westraliense Bougher, Tommerup & Malajczuk (1991).Description
- arrow_drop_downarrow_drop_upCollecting details
Collection 1000134 was collected by N. Bougher on 20th June 1988 in Floreat Park, Western Australia, AUSTRALIA (31.95°S, 115.8667°E, altitude approximately 25 m above sea level - Google maps). The ectomycorrhizal family Myrtaceae (genus Eucalyptus) was present.
The surrounding habitat was described as woodland with a substrate of decomposed 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. 1.4: Forest – Temperate.
According to the GPS data the collection was in the Southwest Australia woodlands 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).
