‘Yeoreumhyang1ho’—a new variety of Flammulina velutipes, light brown in color and adaptable to high temperature—was bred by mating two monokaryons isolated from ‘Garlmoe’ and ‘Konkuk1ho’. It exhibited better quality compared to ‘Geumhyang’ and ‘Garlmoe’ under conditions where temperature was maintained at 16oC, without exposure to low temperature (4oC), during the cultivation period. Bottle cultivation at 16oC required 22, 6, and 10 days for mycelial growth, primordia formation, and growth of the fruit body, respectively. The total cultivation period for ‘Yeoreumhyang1ho’ was observed to be 38 days, which is 3 and 7 days shorter than that for ‘Geumhyang’ and ‘Garlmoe’, respectively. The primordia formation showed remarkable uniformity and the pileus color was observed to be light brown, an intermediate between yellowish ivory of ‘Geumhyang’ and medium brown of ‘Garlmoe’. The yield was 138 g per 850 ml bottle, which was 10% higher than that of ‘Geumhyang’.
