    We carried out a general survey of current situations of P. intermedius S. Y. Chen. Results show that P. intermedius S. Y. Chen is distributed in Dongkeng Township, Jingnan Township and Yanxi Township. It covers an area of 262.51 hm2. The distribution areas are narrow and limited. What’s worse, it suffers from serious destruction and has been withered in large areas. Besides, according to current introduction test, it is difficult to survive in other places. In accordance with Exploring the Criteria for Endangered Categories of Bamboo Species from China put forward by Ma Naixun et al from the Research Institute of Subtropical Forestry of Chinese Academy of Forestry (RISFCAF), we propose incorporating P. intermedius S. Y. Chen into vulnerable species for protection

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
