The optimal conditions for mycelial growth of P. linteus ASI 26011 were 25-30°C and pH 6.0, respectively. The mycelial growth of p. linteus was excellent on MCM medium. In case of carbon sources, the mycelial growth of P. linteus was best on the culture media that were contained with sucrose,k mannose and glucose. Potassium nitrate and sodium nitrate were good for the mycelial growth of p. lingeus as a nitrogen source. For comparison of the mycelial colonization of P. linteus on logs, several techniques of inoculation were tested; the sterilized short log inoculation, drilling inoculation and log-end sandwich inoculation. The mycelial colonization of p. linteus on logs was good in the treatment of sterilized short log inoculation, but poor in the traditional methods such as drilling inoculation and log- end sandwich. The initial mycelial growth and the full cycelial colonzation of p. linteus were the best on 20cm logs under the condition of 42% of moisture content in log. Also the initial mycelial growth of P. linteus was accelerated over 12 hours of sterilization. Burying method of logs after 5-6 months of incubation was the best for formation of basidiocarp of p. linteus. The formation of fruiting body of P. linteus was quite good in the cultivation house at the 31-35°C and over 96% of relative humidity.
