This study was carried out to find a useful mushroom at Chungnam Agricultural Research And Extention Service. Twenty materials used were collected from domestic and exotic area. These races were compared bontanical characteristics to leading varieties by PCR-RAPD methods. Mycelial growth temperature of Chongpung and Myongwol were at 20 to 25 $^{\circ}C$ and 25 to 30 $^{\circ}C$ at PDA medium, respectively mycelial growth of these varieties were similiar at pH 6.5 to 7.5. In case of mushroom cultivation temperature ranges, Chongpung was at 5 to 26$^{\circ}C$ and Myongwol was at 7 to 28$^{\circ}C$, but the optimum temperature range of these were appeared at 15 to 19$^{\circ}C$. Culture temperature of these was 23$^{\circ}C$ and period of mycelial culture was needed 23 to 24 days under 850cc/pp, while was needed 11 to 12 days at waste cotton medium. Cap color of these at first inducing mushroom was all dark blue, but at late growing stages Chongpung was shown as grey, and Myongwol was shown as dark grey. Yield of Chongpung was appeared as 46kg/3.3$m^2$ and that of Myongwol was 41kg /3.3$m^2$, while Chunchu No2 as check was 40kg/3.3$m^2$. Results from PDA medium and PCR-RAPD analysis two of these were different from others.

Rice hull was used as a additive in order to find the effect for incresing of mushroom growth and yield in Chungnam Provincial techinical institution. 1 Treatment of 80% rice hull in small Neutaribeosut mycelial grow duration is shorter about 11 days and yield increased about 7% than conventional culture. 2. In case of Chongpung Neutaribeosut bottle culture, mycelial growth duration is shorter about two to three days in additive of 30 to 80% rice hull compared to conventional but yield similar to conventional. 3. Treatment of 30% rice hull in Agrocybe aegerita bottle culture, mycelial growth and yield increased 6days and 6% than convrntional, respectively 4 Treatment additived of 30% to 40% rice hull in Ganoderma lucidum bottle culture, similar to 454ays demand in mycelial grow duration and 38g yield/bottle in conventioal culture methods.

Rice hull was used as an additive in order to determine the its effect on increse of mushroom growth and yield in Chungnam Provincial techinical institution. In the treatment of 80% rice hull in small Neutaribeosut, mycelial growth duration was shown to be shorter about 11 days and yield increased about 7oie than those of conventional culture. In the case of Chongpung Neutaribeosut bottle culture, mycelial growth duration was shorter about 2 to 3 days in additive of 30 to 80% rice hull compared to conventional, but yield was similar to that of conventional. In the treatment of 30% rice hull in Agrocybe aegerita bottle culture, mycelial growth and yield increased 6 days and 6% than those of convrntional, respectively. In the treatment of 30% to 40% rice hull in Ganoderma lucidum bottle culture, mycelial grow durations were similar 45 days and 38 g/bottle.
