　For the purpose of discovering new bioactive metabolites, a wide range of basidiomycetes, including members with minute basidiocarps which have been underutilized for microbial screening, were collected and isolated. As a result of screening, six novel bioactive metabolites were found. Two of them were found from minute basidiomycetes. Taxonomic study of minute basidiomycetes revealed two new species and two species new to Japan. In addition, 13 taxa of Physalacria were considered to be distributed in Japan. These results suggest the existence of diverse flora of minute basidiomycetes in Japan, such basidiomycetes being promising biological resources for the future.
