Cystoderma list of the species found in Korea is composed of 6 species(Lee & Lee 2000). Cystoderma in Korea is Cystoderma amiaanthinum, Cystoderma carcharias, Cystoderma fallax, Cystoderma granulosum, Cystoderma japonicum and Cystoderma terreii. As the member of Lepiotaceae, Cystoderma belongs under Eumycotina, Basidiomycotina, Eubasidimycotina, Hymenomycetidiae, and Agaricales. Its outer pileus of Cystoderma is serrate radially, a small scale is scattered its peridium. And stipe has a small annulus attached to it. spores is subspore or fusiform, white and it has pseudoamyloid. Each shape, size, shine and quility of fruiting body of Cystoderma is different in the breed and it is important sources of a classification of Cystoderma. Especially, the shapes and colors of various scaly which are on the surface of the fungus are important to the external classification.

This study was conducted to research the effect of Cryptomeria japonica sawdust and branch on the Production of Fruiting body of Pleurotus eryngii. Quantity of fruit body was lower in 5.2things/ bottle but yield of fruit body was higher in 3.5things/ bottle about big fruit body than Douglas-fir sawdust medium on C. japonica sawdust medium, so yield of fruit body was more 45g than Duglas-fir sawdust medium. But in the C. japonica branch sawdust medium, both quantity of fruit body and yield of fruit body was remarkably lower 13.3things/bottle, 42.8g/bottle respectively than Duglas-fir sawdust medium.
