Analysis and Identification of a New Pathogenic Fungus (Antrodia subxantha) Growing on the Ancient Cupressus funebris Trees

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.
