Abstract: Beltraniella jiangxiensis P. Razaghi, M. Raza & L. Cai, Fungal Diversity 124: 47 (2024) Fig. 7 Description. Sexual morph: Undetermined. Asexual morph: Setae numerous, arising from radially lobed basal cells, straight or flexuous, unbranched, single, thick-walled, coarsely verrucose, tanned, 117–169 μm long, 5.14–5.46 μm wide, tapering to a pointed apex, or arising from a dark brown, swollen, radially lobed basal cell, 8.2–14.6 μm in diameter. Conidiophores macronematous, simple or branched at apical regions, thin-walled, swollen at the base, subhyaline to pale yellow, arising from basal cells of setae or from separate, 32–69 × 4–6 µm. Conidiogenous cells polyblastic, integrated, determinate, terminal, geniculate, denticulate, cylindrical, oblong, hyaline to subhyaline, smooth, 12–29 × 3.8–9.3 μm (av. = 19.74 ± 5.82 × 6.32 ± 1.95 μm). Conidia simple, dry, straight, thin-walled, turbinate to obpyriform, rostrate to pointed at proximal end, rounded at distal end, hyaline to subhyaline without a hyaline transverse band, aseptate, 22.3–26.1 × 5.1–8.2 μm (av. = 23.94 ± 1.09 × 6.23 ± 0.78 μm). Culture characteristics. Colonies on PDA at 25 ° C in darkness, occupying an entire 90 mm Petri dish in 14 d. Surface greyish white, flat, dense, concentric rings. Reverse cream-colored or pale brown concentric rings. Materials examined. China • Hainan Province, Ledong Li Autonomous County, Jianfeng Town, on decaying leaves, 11 April 2023, Q. Y. Liu, (HSAUP 3709-1, new host and locality record), living cultures SAUCC 3709-1. GeneBank numbers. SAUCC 3709-1: ITS = PQ 351213, LSU = PQ 351429, RPB 2 = PV 420885, TEF 1 - α = PV 420892. Notes. Phylogenetic analysis showed that our isolate (SAUCC 3709-1) was closely related to Beltraniella jiangxiensis (CGMCC 3.23486 and LC 15868) (Fig. 1). There are no nucleotide position differences between our isolate (SAUCC 3709-1) and Be. jiangxiensis (CGMCC 3.23486 and LC 15868). Morphologically, our isolate (SAUCC 3709-1) fits well with the description of Beltraniella jiangxiensis (CGMCC 3.23486) in having similar setae, conidiophores, conidiogenous cells, and conidia (Liu et al. 2024). Based on the high morphological similarity and no nucleotide differences, we considered our isolate (SAUCC 3709-1) as Be. jiangxiensis. Be. jiangxiensis (CGMCC 3.23486 and LC 15868) were discovered on Camellia sinensis in Jiangxi Province, China (Liu et al. 2024). Based on morphological characteristics and phylogenetic analysis, we report our isolate (SAUCC 3709-1) as Be. jiangxiensis, and this study is the first report of Be. jiangxiensis on decaying leaves and the first recorded in Hainan Province, China.
