Material examined:— CHINA Shaanxi Province: Yulin, Jichang East Road , 38°19’21.16” N, 109°39’54.73” E, 1124 m asl., on stems of Salix psammophila , collected by X. L. Fan, 1 Aug 2013 ( BJFC-S975 ) GoogleMaps ; living culture, CFCC 89629 ; Yulin, Hongshi Gorge , 38°19’40.83” N, 109°42’37.98” E, 1092 m asl., on stems of Salix psammophila , collected by X. L. Fan, 29 Jul 2013 ( BJFC-S978 ) GoogleMaps ; living culture, CFCC 89630 .

Notes: Cytospora chrysosperma is the most commonly recorded Cytospora species with a wide host range ( Deng 1963; Tai 1979; Wei 1979; Chen 2002; Zhuang 2005; Adams et al. 2006). In the current study, the isolates CFCC 89629 and CFCC 89630 were shown to be C. chrysosperma based on phylogenetic analysis and morphological characters. This is the first record of this species on Salix psammophila worldwide.

Cytospora chrysosperma has not been epitypified and therefore we treat BJFC CGHs 10 as an authentic specimen ( Fan et al. 2014). This has proved as consistent results from several other authors without epitypification ( Adams et al. 2005, 2006; Fotouhifar et al. 2010). It makes sense to epitypify this here for further study. Thus fresh collections of Cytospora chrysosperma are needed for epitypification.
