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 .

Figure 2. Phylogram generated from RAxML analysis based on ITS with tef 1 - α sequence data of Aplosporella isolates. The tree was rooted in Alanomyces indica (CBS 134264). The MP, ML (≥ 50 %), and BI (≥ 0.9) bootstrap supports are given near the nodes, respectively. Isolates from this study are marked in blue, and ex-type strains are marked in bold.
