Description.

See Lin et al. 2023 a.

Material examined.

China, Beijing City, Tongzhou District, Central Green Forest Park, 39 ° 52 ' 16 " N, 116 ° 42 ' 04 " E, on the dead branches of Acer truncatum, 12 April 2023, C. M. Tian, Y. M. Liang, C. Peng, Y. Hu & Y. Y. Wu, BJFC - S 1943, living culture CFCC 70743 ; ibid. BJFC - S 1944, living culture CFCC 70738 .

Notes.

Aplosporella yanqingensis was first discovered on the branches of Platycladus orientalis in Beijing (Lin et al. 2023 a). In this study, the two isolates (CFCC 70738 and CFCC 70743) from Acer truncatum formed a clade with 100 % MP, 100 % ML, and 1.00 BYPP values in the multi-locus phylogenetic tree with A. yanqingensis (Fig. 2). Compared with the description of Lin et al. (2023 a), this study has shorter conidia and thinner conidiogenous cells (11.0–16.5 × 6.0–9.0 µm vs. 16.0–21.5 × 6.0–9.5 µm and 5.0–20.5 × 1.0–2.0 µm vs. 6.0–13.5 × 2.0–3.0 µm). Thus, these isolates were identified as A. yanqingensis, and herewith we are providing a new host record for A. yanqingensis, Acer truncatum .
