Summary

Forest ecosystems have include numerous species diversity, and their biological interaction have ecological cycling maintained.

Ectomycorrhizal fungi are symbionts with host tree species belowground and trees enhance their environmental adaptability.

In addition, rare fungal species with high economic value are often found such as these "satoyama" secondary forest, but these species have not been grasped at all.

As our research result, ectomycorrhizal fungal species were classified from 187 species, 41 genera, and 27 families and their species diversity was relatively high. Dominant species were belong to Russulaceae, Inocybaceae, and Amanitaceae.

Further, there were unique mycorrhizal fungal species for each sampling area or each different host tree species.

It was also found that there are differences in fungal community structure depending on forest type. "Satoyama forests" often have complexity forest types with small and patchy structure, and it is possible that the structural features of the forests might be a factor that increases species diversity.
