A new variety of Pleurotus eryngii which is named 'Gonji No. 8' was bred by mating monokaryotic strain isolated from E085D2 and a monokaryotic strain 'aerini No.3' obtained from the Mushroom Research Institute, Gyeonggi-Do A.R.E.S. The characteristics of the new variety 'Gonji No.8' is as follows. The optimum temperature for mycelium growth was from $23^{\circ}C$ to $26^{\circ}C$ on potato dextrose agar (PDA) medium. For the primodia formation and the growth of fruit bodies, the optimum temperature was from $14^{\circ}C$ to $16^{\circ}C$. The period of spawn running was around 30 days at $22^{\circ}C$ and the days taken after the removal of the spawn layer to initiate primodia was seven days. The hardness value of fruit body was $8,432{\pm}2,193$ $g/cm^2$, which was two times more than that of 'Keunneutari No.2'. The yield of 'Gonji No.8' was about 133 g per bottle(900cc) and it was same as 'Keunneutari No.2'.
