Description.

See Pan et al. 2021.

Material examined.

China, Beijing City, Tongzhou District, Hougezhuang Plain Forest , 29 ° 50 ' 24 " N, 116 ° 54 ' 00 " E, on the dead branches of Forsythia suspensa , 8 April 2023, C. M. Tian, S. J. Li & Y. Y. Wu, BJFC - S 1948 , living culture CFCC 70755 ; China, Beijing City, Tongzhou District, Majuqiao Wetland Park , 39 ° 46 ' 12 " N, 116 ° 37 ' 12 " E, on the dead branches of Ginkgo biloba , 2 May 2023, Y. Y. Wu, BJFC - S 1949 , living culture CFCC 70760 ; ibid. on the dead branches of Syringa oblata, BJFC - S 1950 , living culture CFCC 70761 .

Notes.

Based on phylogenetic analyses (Fig. 3 ), three isolates in this study clustered with Dothiorella acericola and formed a clade with 99 % MP, 100 % ML, and 1.00 BYPP values. Dothiorella acericola is reported to be associated with the canker disease of Acer palmatum in China ( Phookamsak et al. 2019). Pan et al. (2021, 2023) found that Do. acericola infests Ziziphus jujuba and Koelreuteria paniculata branches. The fungus was also recorded on dead branches of Euonymus japonicus ( Lin et al. 2023 b) . This is the first discovery of this fungus in the host families Oleaceae and Ginkgoaceae .

Figures

Figure 3. Phylogram generated from RAxML analysis based on ITS, tef 1 - α, and tub 2 sequence data of Dothiorella isolates. The tree was rooted in Neofusicoccum luteum (CBS 562.92) and Neofusicoccum parvum (CMW 9081). 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.
