Abstract: Setophoma zoysiae H. Liu & H. Sang sp. nov. Fig. 14 Etymology. Name refers to its host genus Zoysia. Description from living culture CMML 20-14. Sexual morph: undetermined. Asexual morph: Sporulation observed on OA media (Fig. 14 b – f). Conidiomata produced on surface of colonies (Fig. 14 b, c). Conidia ellipsoidal to subcylindrical, aseptate, 3.0–4.6 × 1.8–2.5 μm (Fig. 14 d – f). Type. Korea • South Jeolla Province, Hwasun, isolated from roots of Zoysia japonica, October 2020, H. Liu and H. Sang, holotype CMML 20-14 H (permanently preserved in a metabolically inactive state), ex-holotype CMML 20-14, ex-isotype CMML 20-15. Culture characteristics. Colony reaching 28.12 mm diam. in darkness after 7 days at 25 ° C on PDA, front side white to light pink, reverse side yellow to sandy brown, mycelia dense (Fig. 14 a). Notes. Phylogenetic analysis was conducted using dataset from combined sequences of ITS, LSU, TEF 1, RPB 2 and TUB 2. The strains CMML 20-14 and CMML 20-15 formed a distinct single branch in the genus Setophoma, supported with a high statistical support (100 % / 1.00) (Fig. 15), sister to clade containing ex-type strain (CBS 335.29) and representative strains (CBS 335.87, CBS 377.52 and CPC 18417) of S. terrestris. However, conidia of these two strains are smaller than those of S. terrestris (previously Phoma terrestris, 4.5–5.5 × 1.8–2.3 μm; Hassen (1929)). Hence, Setophoma zoysiae sp. nov. was introduced in this study to accommodate CMML 20-14 and CMML 20- 15 in the genus Setophoma.
