Cytospora sophoriopsis X. L. Fan & C. M. Tian , Persoonia 45: 39 (2019).

Description.

See Fan et al. (2020).

Materials examined.

China • Xinjiang Uygur Autonomous Region, Altay Prefecture, Altay City, Alahake Town, Haxionggou , from branches of Betula pendula , 7 October 2024, Rong Ma, Caixia Wang & Hailong Lu ( XJAU 4048 , cultures CFCC 71679 , CFCC 71680 , CFCC 71681 and CFCC 71682 ) .

Notes.

Cytospora sophoriopsis was introduced on cankered branches of Styphnolobium japonicum ( Fan et al. 2020) . This fungus was later confirmed as poplar and willow canker pathogens in China ( Lin et al. 2022, 2023). In this study, we firstly discovered this species from Betula pendula in XUAR (Fig. 3 ).
