Hebeloma hiemale Bres. in Arctic/Alpine Habitats

Abstract

Hebeloma hiemale Bres. 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, including Salix and Populus. However, it is not generally regarded as an arctic/alpine fungus and we are not aware of any previous reports of H. hiemale in these habitats. During ISAM VIII 2008 this species was collected with Salix reticulata on the Beartooth Plateau in Montana above tree-line at 3000 m asl. We also report a number of other arctic or alpine collections of H. hiemale from Greenland, Svalbard, Iceland and the U.S.A. (Wyoming and Colorado). This is the first report of H. hiemale from the Rocky Mountain alpine zone.
