  • arrow_drop_downarrow_drop_upCollecting details

    Collection 19085 was collected by E. Allen, M. Allen, det: J. Trappe (10785) on 21st August 1993 in Kenai Fjords National Park, Sunlight Glacier. , Alaska, UNITED STATES (approx. 59.7482°N, 149.9827°W, altitude approximately 10 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Alnus), Pinaceae (genus Picea) and Salicaceae (genus Salix) were present.

    The surrounding habitat was described as not recorded.

    According to the GPS data the collection was in the Pacific Coastal Mountain icefields and tundra 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).
