要旨本文	The effect of clearcutting on the diversity of microfungi inhabiting needle litter was investigated in temperate and boreal coniferous forests in five provinces across Canada. Standardized needle litters of Pseudotsuga menziesii and Picea mariana were incubated on the forest floor of clearcut and adjacent mature stands and used as materials for fungal isolation. A total of 852 microfungal isolates were obtained from 200 needles, and these isolates were classified into 57 species. Mean values of species richness of microfungi per needle were significantly lower in clearcut than in mature stands and significantly different between the five provinces, whereas the species richness was not significantly different between two needle species. The decreased species richness in clearcut sites were mainly attributed to the decrease of seven major microfungal species.
