Niesslia dimorphospora W. Gams & Stielow 2019

Niesslia dimorphospora (W. Gams) W. Gams & Stielow (2019). Fig. 8 Culture characteristics. Colony reaching 53.82 mm diam. after 7 days in darkness at 25 ° C on PDA, surface initially floccose, later slimy, white on front and reverse sides (Fig. 8 a). Description from living culture CMML 20-40. Sexual morph: undetermined. Asexual morph: Sporulation abundant on MEA. Phialides 40–75 μm long, 1.5–2.3 μm wide, thick-walled. Conidia smooth-walled, globose, 4.5–6.5 μm diam., or ellipsoidal, slightly curved, 6.5–10.5 × 2.2–3.8 μm (Fig. 8 b – k). Type. Korea • South Jeolla Province, Hwasun, isolated from roots of Zoysia japonica, October 2020, H. Liu and H. Sang, living cultures CMML 20-40, CMML 20-41 and CMML 20-42. Notes. Niesslia dimorphospora typically produce dimorphic conidia (globose and ellipsoidal). In multi-loci phylogenetic analysis using gene sequences of ITS, TEF 1, TUB 2 and RPB 2, three strains (CMML 20-40, CMML 20-41 and CMML 20-42) were clustered into a clade containing ex-type strain of N. dimorphospora (CBS 785.69) and representative strain CBS 361.76 with high statistical support (100 % / 1.00) (Fig. 9). This is the first record of N. dimorphospora associated with Z. japonica in Korea.
