| Popis: | We isolated Tulasnella spp. from Spiranthes sinensis var. amoena, a Japanese native winter green terrestrial orchid collected in Tsukuba City, Ibaraki Pref., Japan. 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 five clades were correlated, and four morpho-phylogenetic groups were identified. Thus, Tulasnella deliquescens including two phylogenetic subgroups and three new species, Tulasnella dendritica sp. nov., Tulasnella ellipsoidea sp. nov., and Tulasnella cumulopuntioides sp. nov., were recognized in this study. In this study, the monilioid cell chain morphology is newly defined, and is suggested as a useful taxonomic characteristic in the asexual stage of Tulasnella spp. |
