Description.

See Du et al. 2017.

Material examined.

China, Beijing City, Tongzhou District, Majuqiao Wetland Park , 39 ° 46 ' 12 " N, 116 ° 37 ' 12 " E, on the disease branches of Cotinus coggygria var. cinereus , 2 May 2023, Y. Y. Wu, BJFC - S 1931 , living culture CFCC 70746 .

Notes.

Aplosporella ginkgonis was first reported in Gansu Province, China, causing canker and dieback disease in Ginkgo biloba and Morus alba ( Du et al. 2017) . Zhu et al. (2018) and Li et al. (2023) discovered the species on Rhus typhina and Zanthoxylum bungeanum , respectively, extending its host range. In the present study, one isolate ( CFCC 70746 ) was identified as A. ginkgonis based on the phylogenetically highly supported clade with 99 % MP, 95 % ML, and 0.94 BYPP values (Fig. 2 ) and morphological characteristics. This is the first report of A. ginkgonis on Cotinus coggygria var. cinereus .

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.
