【 摘 要 】

In all 143 fungal taxa collected in the years 1971 and 1974 are presented from different habitats of the Arctic and Subarctic tundra in the Keewatin and Franklin areas of N.W.T., Canada and at Fort Churchill, Manitoba. Of the 143 species reported, 122 species are new in N.W.T. and Fort Churchill. The diversity of mycorrhizal species was highest in drier lichen-moss and moss tundra heaths, and in late snow patches, the most common genera beingCortinarius ,Inocybe ,Hebeloma ,Lactarius , andRussula . The most frequent saprobic fungi wereHygrocybe ,Arrhenia ,Clitocybe ,Galerinasome of which are bryophilous andHelvellaspecies. In the forest tundra, numerous species typical of conifer forests were found as mycorrhizal symbionts ofPiceaandLarix . These collections remain the primary source of information on macrofungi in this region.
