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 View Figure 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.
