To investigate fungi involving sclerotium formation, we collected sclerotia from forest soils of Mt. Ontake, Gifu prefecture, Japan, and created the clone-library of their ITS regions of rDNA. We also cultured fungi from those sclerotia, followed by identifying fungal species. The results of the clone-library analyses suggested that Cenococcum geophilum, a fungus known for sclerotium formation, was included in the isolated fungi, which were mostly ascomycetes. Although culturing C. geophilum was not successful, three dark septate endophytes (DSE), all of which were unidentified, formed sclerotia on the artificial medium. Therefore, the sclerotia examined in this study might have been formed by not only C. geophilum but also by other fungi.
