    Abstract:
    Through the comparative study on the appearance characters and internal structure of cultivated and wild Ganoderma lucidum in Huoshan,this paper provides a reference for the further study of G. lucidum. In this study,the similarities and differences between cultivated G. lucidum " Huozhi No. 1" and wild G. lucidum in Huoshan were compared by means of character observation,optical microscopy and scanning electron microscope( SEM). The results showed that the pileus color of " Huozhi No. 1" was yellowish brown and thicker,while that of wild G. lucidum was mainly reddish brown,the context was thinner,and there were gravel and rotten wood at the bottom of the stipe. A clear skeletal hyphae and binding hyphae were observed in cultivated and wild G. lucidum,but there was no significant difference. The shell layer,context layer,mediostratum layer and spores of cultivated and wild G. lucidum were observed by SEM,and the results showed that there was no significant difference. It was found that the mediostratum of " Huozhi No. 1" was thin and irregular,while the mediostratum of wild G. lucidum was neat and compact. There were two types of spores in wild G. lucidum,one of which retained the outer wall of spore type Ⅰ,with tiny pores on the surface. The other is type Ⅱ spores with many spinous processes on the surface,which may be formed by type Ⅰ spores falling off the outwall. In this study,the appearance characters and internal structure of cultivated and wild G. lucidum in Huoshan were systematically observed and compared,which provided theoretical basis and reference for the identification and quality evaluation of cultivated and wild G. lucidum.
