摘 要：
以翠云廊古柏树上采集到的拟黄薄孔菌(Antrodia subxantha)为材料,经戴玉成和贺新生教授通过形态观察分析将其命名为:拟黄薄孔菌(Antrodia subxantha Y.C.Dai&X.S.He.)。为了进一步证明其是否为新的树木病原菌物种,和与其它物种的亲缘关系,首次对此真菌采用形态分析和构建ITS序列系统发育树进行分子生物学分析,发现该物种被单独的聚类成为一个种,与其最新发现的西加薄孔菌(Antrodia sitchensis)同源相似度为94%,并结合形态学上的差异,结果证明其是四川古柏树上的一种新病原菌,它能够引起古柏树树根和树干褐腐病,最终导致树木枯死。

摘 要：
Antrodia subxantha was collected on the dead wood of the ancient cupressus funebri trees growing along the Cuiyun Gallery.It was identified as a new species named for Antrodia subxantha on morphology by professors He Xinsheng and Dai Yucheng.In order to prove it as a new species,for the first time,the morphology analysis and molecular techniques annlysis were adopted to establish ITS sequences.As a result,Antrodia subxantha was discovered to be able to be clustered as a new species,and its homologous similarity was 94% with Antrodia sitchensis.Finally,It was further proved as a new species on the ancient cupressus funebri trees in Sichuan,could cause the roots and trunk brown rot,eventually and led the trees to become dead.
