These isolates were classified into four morphotypes according to morphological characters, i.e., shape of monilioid cells and branch type of monilioid cell chains, while they were separated into five clades by molecular phylogenetic analysis based on the rDNA 5.8S and D1/D2 regions. The four morphotypes and the five clades were correlated. In addition, these five genetically different groups were distinguishable in their physiological characters. Thus, Epulorhiza repens (including two genetic subgroups in E. repens) and three new species, Epulorhiza dendritica sp. nov., Epulorhiza ellipsoidea sp. nov., and Epulorhiza cumulopuntioides sp. nov., were recognized in this study. This study built a new definition of the type of monilioid cell chain as a taxonomical character. In addition, this study showed species diversity of orchid mycorrhizal fungi in the genus Epulorhiza of S. sinensis var. amoena f. amoena, which was believed to consist of only one species, E. repens.} }
