description The genus contains multiple species causing dollar spot (DS) on turfgrass worldwide. In November 2020, 119 isolates were obtained from symptomatic seashore paspalum at golf courses in Hainan province and identified to species level based on partial sequence of the internal transcribed spacer (ITS) region. A total of 45 and 22 isolates were identified as and , respectively; the remaining 52 isolates defined a new clade. Isolates from this clade were further selected for phylogenetic, morphological, and biological analyses. Maximum likelihood and Bayesian methods were implemented to obtain phylogenetic trees for partial sequences of the ITS, , and genes. The selected isolates consistently fell into a distinct, well-supported clade within . Morphological and biological characteristics were observed among the different species in . Altogether, this study described a new species, , which has widespread distribution in Hainan, China. These findings may have important implications for the management of DS disease.
