Hebeloma hiemaleBres. in Arctic/Alpine Habitats

[摘要] Hebeloma hiemaleBres. is a frequently collected species and occurs with many hosts in a wide variety of habitats. It is an ectomycorrhizal species that has been recorded with a broad range of both deciduous and coniferous trees, includingSalixandPopulus . However, it is not generally regarded as an arctic/alpine fungus and we are not aware of any previous reports ofH. hiemalein these habitats. During ISAM VIII 2008 this species was collected withSalix reticulataon the Beartooth Plateau in Montana above tree-line at 3000 m asl. We also report a number of other arctic or alpine collections ofH. hiemalefrom Greenland, Svalbard, Iceland and the U.S.A. (Wyoming and Colorado). This is the first report ofH. hiemalefrom the Rocky Mountain alpine zone.
