Pseudorhypophila poae H. Liu & H. Sang 2025, sp. nov.

Pseudorhypophila poae H. Liu & H. Sang sp. nov. Fig. 18 Etymology. Name refers to its host family Poaceae. Description from living culture CMML 20-36: Sexual morph: undetermined. Asexual morph: Sporulation abundant on MEA. Conidiophore erect, 1.5–2.5 μm in width, Conidia solitary or in clusters, pyriform, obovoid or triangular, 4.2–5.6 × 2.5–4.5 μm (Fig. 18 b – e). Type. Korea • South Jeolla Province, Hwasun, isolated from roots of Zoysia japonica, October 2020, H. Liu and H. Sang, holotype CMML 20-36 H (permanently preserved in a metabolically inactive state), ex-holotype CMML 20-36, ex-isotype CMML 20-89. Culture characteristics. Colony reaching 82.88 mm diam. on PDA after 7 days in darkness at 25 ° C, white to buff in both front and reverse sides (Fig. 18 a). Notes. The genus Pseudorhypophila was recently introduced by accommodating four species including Triangularia mangenotii, Zopfiella marina, Z. pilifera and Z. submersa (Harms et al. 2021). In phylogenetic analysis using combined sequences of ITS, LSU, RPB 2 and TUB 2, strains in the present study CMML 20-36 and CMML 20-89 formed a single clade in the genus Pseudorhypophila supported with a high statistical support (100 % / 1.00) close to clade comprising ex-type strains of P. pilifera (CBS 413.73) and P. mangenotii (CBS 419.67) (Fig. 19). However, both P. pilifera and P. mangenotii produce sexual morph, which was not observed in strains CMML 20-36 and CMML 20-89. In addition, these two strains differ from P. mangenotii in producing conidia singly or in clusters, whereas the latter produces conidia singly (Harms et al. 2021). Therefore, based on phylogenetic analysis and morphological characteristics, Pseudorhypophila poae sp. nov. was introduced in this study.
