Wang, culture YCW 2118.</p> <p>Notes.</p> <p> <i>Didymella sinensis</i> is closely related to <i>D. pomorum</i>. It can be observed from different host plants in a wide range, such as <i>Cerasus pseudocerasus</i> (Rosaceae), <i>Dendrobium officinale</i> (Orchidaceae) and Urticaceae. The sexual morph was characterised by ascomata aggregated, globose to irregular, brown, small and papillate. Asci were bitunicate, clavate to short cylindrical; Ascospores were biseriate, ellipsoidal, straight to slightly curved, hyaline, apex obtuse, medianly 1 - septate (Chen et al. 2017). In the present study, eight isolates from healthy tea plant leaves phylogenetically grouped with <i>D. sinensis</i> with high statistical support (Fig. 2). This is the first report of <i>D. sinensis</i> isolated from <i>C. sinensis</i>.</p>Published as part of <i>Wang, Yuchun, Tu, Yiyi, Chen, Xueling, Jiang, Hong, Ren, Hengze, Lu, Qinhua, Wei, Chaoling & Lv, Wuyun, 2024, Didymellaceae species associated with tea plant (Camellia sinensis) in China, pp. 217-251 in MycoKeys 105</i> on pages 217-251, DOI: 10.3897/mycokeys.105.11953

Under the current circumstance of Didymellaceae, it belongs to <i>Didymella</i>. <i>Didymella segeticola</i> can develop abundant aerial mycelium and black pycnidia on oatmeal agar (OA) plates (Chen et al. 2015 b). Zhao et al. (2018) first reported that <i>D. segeticola</i> can cause tea leaf spot in the tea plantations in Guizhou Province, which results in leaf fall and a huge loss of tea leaves. In the present study, 171 isolates from diseased tea plant leaves formed a monophyletic subclade, closely related to <i>D. bellidis</i> with high statistical support (Fig. 2).</p>Published as part of <i>Wang, Yuchun, Tu, Yiyi, Chen, Xueling, Jiang, Hong, Ren, Hengze, Lu, Qinhua, Wei, Chaoling & Lv, Wuyun, 2024, Didymellaceae species associated with tea plant (Camellia sinensis) in China, pp. 217-251 in MycoKeys 105</i> on pages 217-251, DOI: 10.3897/mycokeys.105.11953

It was first isolated from seedlings of <i>Acca sellowiana</i> in Italy (Chen et al. 2017) and reported in the dairy setting (Rodríguez et al. 2023). In addition, this species significantly reduced both leaf area of soybean consumed aboveground by caterpillars and number of cysts produced belowground by nematodes (Rivera-Vega et al. 2022). In the present study, one strain was isolated from healthy tea plant leaves. This is the first report of <i>E. italicum</i> isolated from <i>C. sinensis</i>.</p>Published as part of <i>Wang, Yuchun, Tu, Yiyi, Chen, Xueling, Jiang, Hong, Ren, Hengze, Lu, Qinhua, Wei, Chaoling & Lv, Wuyun, 2024, Didymellaceae species associated with tea plant (Camellia sinensis) in China, pp. 217-251 in MycoKeys 105</i> on pages 217-251, DOI: 10.3897/mycokeys.105.11953

Pycnidia were black-brown and mostly spheroid and conidia were ellipsoidal to oblong, aseptate and hyaline (Chen et al. 2017; Li et al. 2023). It was first discovered from <i>Acer palmatum</i> (Aceraceae), <i>Camellia sinensis</i> (Theaceae), <i>Podocarpus macrophyllus</i> (Podocarpaceae) and <i>Vitex negundo</i> (Verbenaceae) (Chen et al. 2017). As a phytopathogen, it can cause leaf spot, leaf blight and stalk rot on many plants (Xu et al. 2022; Li et al. 2023; Wang et al. 2023). In the present study, three strains were isolated from healthy tea plant leaves.</p>Published as part of <i>Wang, Yuchun, Tu, Yiyi, Chen, Xueling, Jiang, Hong, Ren, Hengze, Lu, Qinhua, Wei, Chaoling & Lv, Wuyun, 2024, Didymellaceae species associated with tea plant (Camellia sinensis) in China, pp. 217-251 in MycoKeys 105</i> on pages 217-251, DOI: 10.3897/mycokeys.105.11953
