Abstract
We identified polypores excavated from the Shimo-yakebe site, Higashi-murayama city, Tokyo. We found Ganoderma applanatum, Daedalea dickinsii, and Abundisporus pubertatis from horizons of the Jomon period and only G. applanatum from horizons of the Kofun or later periods. Based on the ecology of each species and the size of individuals, we tried to clarigy forest vegetation around the site.
