Tricholoma giganteum, belongs to Tricholomataceae of Tricholoma, is also well-known as the medicinal mushroom in Taiwan. "Backryon" was the first variety developed by intra-specific crossing in Korea. It was improved with hybridization between monokaryotic strain derived from MKACC50852 and MKACC 50853. The optimum temperature of mycelial growth and fruiting body development were $25{\sim}30^{\circ}C$ and $20{\sim}25^{\circ}C$, respectively. The color of fruitingbody was pure white and cap type was umbrella. It suggested that 'Backryon' was new commercial variety for small-sized cultivator during the summer season.
